Ministers Will Relax Rules To Build Small Nuclear Reactors
The title of this post is the same as that of this article in The Times.
This is the sub-heading.
Britain’s five nuclear power stations, which generate about 6GW in total, powering 13 million homes, are all nearing the end of their lives
These first three paragraphs indicate the reasons why, the government wants to relax the rules.
Ministers are preparing to relax planning rules to make it easier to build mini nuclear power plants in more parts of the country in order to hit green energy targets and boost the industry.
They are also examining whether it is possible to streamline the process for approving the safety of new nuclear power plants as a way to reduce construction delays.
At present rules state that only the government may designate sites for potential nuclear power stations, of which there are eight, severely limiting where they can be built.
The article includes a vote and surprisingly to me, the vote embedded in the article, shows 92 % in favour of relaxing the rules and only 8 % against.
I must admit these figures surprise me, as I’d have thought more would have been against.
Certain Words Frighten The Public
It is because nuclear is one of those words, that I felt that the vote in favour would have been much lower.
Regular readers of this blog will know, that in the 1960s,, I worked for ICI doing itinerant computing and instrumentation tasks, in my first job after leaving Liverpool University with a degree in Control Engineering.
I can now classify the experience as a superb apprenticeship, where I learned a lot that has been useful to me in later life.
For a time, I was working on nuclear magnefic resonance or NMR scans. ICI Mond Division in Runcorn had one of the best installations for analysing chemicals using this technique, which is described in this Wikipedia entry, which starts with these sentences.
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are disturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca. 20 tesla, the frequency is similar to VHF and UHF television broadcasts (60–1000 MHz).
One day, the Senior Scientist, who ran the machine came in to work and announced that the property of nuclear magnetic resonance would be replacing X-rays, as the technology had just been used to give a three-dimensional image of something like the tail of a mouse.
Now fifty-five years later, many if not most of us have had MRi scans.
The Wikipedia entry for Magnetic Resonance Imaging or MRi, explains, what happened to the dreaded N-word.
MRI was originally called NMRI (nuclear magnetic resonance imaging), but “nuclear” was dropped to avoid negative associations.
Perhaps, it would be easier to build nuclear power stations, if the level of science teaching in the UK was better.
The Three Paragraphs In Detail
Earlier, I copied three paragraphs from The Times, into this post.
I shall now look at each in detail.
Paragraph 1
Ministers are preparing to relax planning rules to make it easier to build mini nuclear power plants in more parts of the country in order to hit green energy targets and boost the industry.
I was in Suffolk, when the planning of Sizewell B was undertaken.
There appeared to be little strong opposition, but the general feeling was what there was from second home owners, who were worried that the value of their holiday home would decline.
Employment and commerce created by Sizewell B was certainly good for the area in lots of ways.
At the time, my late wife; C was practicing as a family barrister in chambers in Ipswich. She believed that the building of Sizewell B had had a good effect on the area, as it had injected work and money, which had created the finance to allow a couple to end a marriage, that had long since died. She stated a couple of times, that Sizewell B was good for her practice.
Paragraph 2
They are also examining whether it is possible to streamline the process for approving the safety of new nuclear power plants as a way to reduce construction delays.
My worry about streamlining the process for approving safety, is that we approve nuclear power stations so rarely, do we have the qualified personnel to replace elapsed time with people. I would suggest that we don’t.
But we could have.
- We have some excellent universities, where Nuclear Engineering can be studied.
- How many personnel leave the Royal Navy each year, who could be trained as nuclear safety inspectors?
- If say Rolls-Royce and/or Hitachi are building several small modular nuclear reactors a year in the UK, then nuclear engineering will become fashionable, as electronics was for my generation of engineers and it will attract the brightest students.
Perhaps an established university, with access to the needed skills should be funded to set up a Nuclear Safety Institute
Paragraph 3
At present rules state that only the government may designate sites for potential nuclear power stations, of which there are eight, severely limiting where they can be built.
I can envisage new small modular nuclear reactors being built in the UK, where there is a need for lots of electricity to support developments like.
- Offshore wind farms
- Data centres
- Green steelmaking
- Metal refining
- Hydrogen production.
Rolls-Royce have said that their small reactors will be around 470 MW, so I could imagine power stations of this size being placed on disused coal-fired power station sites to boost power in an area. I have already suggested building some on Drax in The Future Of Drax Power Station.
In some locations, the choice could be between a small modular nuclear reactor and some form of energy storage.
Powering Germany
But there is one controversial area, where we can take advantage.
- The Germans are very short of electricity because of their reliance on coal and Russian gas that needs to be replaced.
- The 1.4 GW NeuConnect interconnector is being built by European and Japanese money between the Isle of Grain and Wilhelmshaven.
- The AquaVentus hydrogen system could be extended to Humberside to link with UK hydrogen production and storage.
- A couple of small modular nuclear reactors could be built on Humberside to back up hydrogen production, when the wind isn’t blowing.
But Rolls-Royce and other companies have been putting small nuclear reactors close to the sea bed safely for decades, so why no design an offshore reactor that can be placed at a safe distance offshore?
We would need to solve the Putin and friends problem first, but I can see the UK exporting a lot of electricity and hydrogen produced by nuclear energy.
Could Liverpool Develop A Massive Zero-Carbon Data Centre?
There is an article in The Sunday Times today, which is entitled Google Signs Nuclear Deal To Power AI Data Centres.
These are the first three paragraphs of the article.
Google has struck a deal with a nuclear power start-up to provide low-carbon energy for its data centres and AI operations, marking a world-first in the tech industry.
The California-based company said the agreement to buy energy from multiple small modular reactors developed by Kairos Power could help spur a nuclear revival in America.
The first reactor is scheduled to come online in America by 2030, followed by additional deployments through 2035.
I am not against nuclear-powered data centres, but could Liverpool build a massive zero-carbon data centre?
This Google Map shows Liverpool Bay, which is a vast expanse of water that stretches along the North Wales coast to Anglesey and all the way to the Isle of Man.
Note.
- The Isle of Man in the North-West corner.
- Liverpool, Birkenhead and the River Mersey in the South-East corner.
- Anglesey in the South-West corner.
- Blackpool with Morecambe Bay to its North in the North-East corner.
Liverpool Bay could be one of Europe’s zero-carbon energy powerhouses.
Wind Farms In Liverpool Bay
At the present time, these wind farms are producing electricity or planned in Liverpool Bay.
- Barrow – 90 MW – Commissioned in 2006
- Burbo Bank – 90 MW – Commissioned in 2007
- Burbo Bank Extension – 258 MW – Commissioned in 2017
- Gwynt y Môr – 576 MW – Commissioned in 2015
- North Hoyle – 60 MW – Commissioned in 2003
- Ormonde – 150 MW – Commissioned in 2012
- Rhyl Flats – 90 MW – Commissioned in 2009
- Walney – 367 MW – Commissioned in 2010
- Walney Extension – 659 MW – Commissioned in 2018
- West if Duddon Sands – 389 MW – Commissioned in 2014
- Awel y Môr – 500 MW – Planned
- Morecambe – 480 MW – Planned
- Mona – 1500 MW – Planned
- Morgan – 1500 MW – Planned
Note.
- 2509 MW has been commissioned.
- 3980 MW is being planned.
- That is a total of 6489 MW
I suspect more space in Liverpool Bay could be developed with wind farms.
Mersey Tidal Power
The Mersey Tidal Power project has a web site.
If it is built, it will probably be built by the South Korean company; K-Water and use some of the design principles of the Sihwa Lake Tidal Power Station.
It will likely have an output of around 1 GW and take ten years to build.
In the 1970s, I did some project management consultancy for Frederick Snow and Partners, and they showed me their plans for a Severn Barrage.
Their futuristic vision for the Severn Estuary was never built, as the Prime Minister of the time; Harold Wilson, felt coal was the future. See Last Of The Many!
I suspect that the Mersey Tidal Power project will be another variation on a proven theme.
Morecambe Bay Bridge And Tidal Barrage Proposal
In the Wikipedia entry for Morecambe Bay, there is a proposal for a bridge and tidal barrage across the bay, where this is said.
In 2004, a proposal was made to build a bridge across the bay flanked by wind turbines and using tidal power. Proposals from Northern Tidal Power Gateways in 2019 outlined a tidal barrage with a road running along on top.
If the Mersey Tidal Power project is a success, then why wouldn’t one across Morecambe Bay, be one too?
500 MW of zero-carbon tidal power would do nicely!
Nuclear Sites At Calder Hall, Heysham And Wylfa
These three nuclear stations have supplied electricity to the North-West of England.
- Calder Hall was the original Magnox site, which the Wikipedia entry says had a nameplate capacity of 240 MW and was decommissioned in 2003, after running for 47 years.
- Heysham is a powerful site which the Wikipedia entry says has a nameplate capacity of 2452 MW and will be decommissioned in 2028.
- Wylfa is an older, smaller Magnox site which the Wikipedia entry says had a nameplate capacity of 1190MW and was decommissioned in 2015.
As the sites are cleared, I am sure that we’ll see more nuclear power stations built on the sites.
How Much Electricity Does A Data Centre Use?
I found this paragraph in an NESO document.
Regardless of this, if we were to use existing market data and modelling projections, this could point to annual data centre electricity consumptions of between 3.6 TWh in 2020 to as much as 35 TWh by 2050.
Dividing by the hours in a year, indicates that an individual data centre could use between 0.4 and 4 GW of electricity.
Using my rough figures here from wind, tidal and nuclear, I suspect that the power on the Mersey will generate enough power for at least one data centre.
Liverpool Is On The Right Side Of The Country For Cables To North America
Cables will go straight out of Liverpool Bay, pass to the North of Ireland and across the Atlantic to somewhere like Puget Sound.
Liverpool has a superb location for a Transatlantic data centre, that connects to networks on both sides of the pond.
Could Underwater Data Centres Be Developed In Liverpool Bay?
This page on the Microsoft web site is entitled Microsoft Finds Underwater Datacenters Are Reliable, Practical And Use Energy Sustainably
These three paragraphs detail the research.
Earlier this summer, marine specialists reeled up a shipping-container-size datacenter coated in algae, barnacles and sea anemones from the seafloor off Scotland’s Orkney Islands.
The retrieval launched the final phase of a years-long effort that proved the concept of underwater datacenters is feasible, as well as logistically, environmentally and economically practical.
Microsoft’s Project Natick team deployed the Northern Isles datacenter 117 feet deep to the seafloor in spring 2018. For the next two years, team members tested and monitored the performance and reliability of the datacenter’s servers.
I would assume that Microsoft have continued the research, as with something like this you can’t be too careful.
But it would appear, that data centres and their servers could be submerged under the waters of Liverpool Bay.
London And Liverpool Will Be Under Two Hours By Train Within A Year
New Class 807 trains, which will be delivered within a year, will improve the train service between the two cities.
- Train times will be brought to around or even below two hours.
- , The extra trains will allow a second hourly service to be added.
- The extra service will additionally stop at Liverpool South Parkway station, for the airport.
- High Speed Two is claiming one hour and fifty minutes, between London and Liverpool.
Liverpool already has one of the best rail terminals in the North of England, as these pictures show.
With these service improvements, it will have a service to London and the South, that will be second to no other Northern station.
Liverpool Has A Refurbished Partly-Underground Suburban Railway With New Trains
Liverpool’s Metro is one of the best in Europe for a medium-sized city.
The Metro is also expanding with new routes and stations.
These pictures show the new Headbolt Lane station, which is swerved by the UK’s first battery-electric trains.
Liverpool Has Easy Access To Two International Airports
There are two international airports close by; Liverpool John Lennon and Manchester International.
- For Liverpool Airport, it’s a bus from Liverpool South Parkway station or an express bus from Liverpool city centre.
- For Manchester Airport, it’s a train from Lime Street station.
I am fairly sure, that a hydrofoil could connect Liverpool’s Waterfront and the Tidal Barrier to the airport.
North-West England Has A Rich University Tradition
Liverpool, Manchester and the surrounding area has several world-class universities and research establishments.
Some like The Pandemic Institute would be able to find uses for all the computing power and artificial intelligence on offer at a powerful data centre.
Liverpool Is A World City
Liverpool is a World City, where there is plenty of sport, entertainment and things to do.
Conclusion
Liverpool is installing the power infrastructure for a very large data centre, that will be able to handle the world’s largest and most difficult problems.
Hinkley Point C Fish Protection Plans Attacked By Environmental Organisations
The title of this post, is the same as that of this article on New Civil Engineer.
This is the sub-heading.
Revised plans to protect fish from water intake tubes for the Hinkley Point C nuclear power plant on the Severn Estuary have come under fresh criticism from environmental organisations.
These three paragraphs outline the story.
EDF recenrly proposed plans to create a saltmarsh at the Somerset nuclear plant site as an alternative to an acoustic fish deterrent. This followed the Environment Secretary having ruled in 2021, in line with Environment Agency recommendations, that the plant should install an acoustic fish deterrent.
The plant is scheduled to circulate 120,000l of water per second from the Bristol Channel to the nuclear power station through 8km underground tunnels to provide cooling for the power station’s systems.
A group of environmental non-governmental organisations (eNGOs) issued a statement coordinated by Somerset Wildlife Trust saying Hinkley Point C “will have a significant impact on marine and migratory fish including already vulnerable Atlantic salmon, twaite shad and European eel over its lifetime”.
This Google Map shows Lake Michigan, which was where I came across another tale of fish and nuclear power.
Note the red arrow, which marks the DC Cook Nuclear Power Plant.
This second Google Map shows a close-up of the plant.
The power plant sits on the shores of Lake Michigan, from which it gets its cooling water.
In the early 1980s, after the Three Mile Island accident in 1979, I was given a tour of two nuclear power stations of which this plant was one and Shippingport or Beaver Valley was the other. Both were Artemis customers and one of the projects they were using the software on, was to plan and document all the Three Mile Island modifications or TMIs.
But it’s the Cook power plant that I remember.
- I’d turned up at Benton Harbor Airport on a very cold, snowy evening and I remember that the Hertz representation had got all the cars running so customers could drive away in the warm.
- DC Cook was impressive and very well run, and it was a very good customer visit.
- The fishy tale, I heard there was that the warm water from the power station attracted the fish and that some locals in the winter took to fishing through the ice of Lake Michigan. Occasionally, they fell through the ice.
- I was told, that some locals felt that the plant should be shut because of this, but it’s still running forty years after my visit.
- Lunch was interesting, as we went to a Michigan version of the famous Rook restaurant in the Two Ronnies. Except that every dish on the menu had something to do with beans, as that is the area of the US, where navy (baked) beans are grown. They even had a bean savoury for afters!
This article from the Huron Daily Tribune is entitled Fish Force Michigan Nuke Plant Shut Down, where these are the first two paragraphs.
Officials shut down a nuclear power plant on the eastern shore of Lake Michigan on Thursday after a large number of fish swam into the plant’s cooling-water system.
The two reactors at Donald C. Cook Nuclear Plant were idled as workers removed the fish and monitored the cooling system. It wasn’t clear when the reactor would be restarted, owner and operator American Electric Power Co. Inc. said in a statement.
It does appear that Cook was suffering from fish in the system.
I hope this doesn’t predict more delays for Hinckley Point C.
Wylfa: UK Government In Talks To Buy Nuclear Site – Report
The title of this post, is the same as that as this article on the BBC.
This is the sub-heading.
The UK government is reportedly in talks to take control of a site in north Wales where a planned nuclear project was scrapped in 2019.
These paragraphs outline the story.
State-owned Great British Nuclear is “in early discussions” with Hitachi, which owns the land at Wylfa, on Anglesey, the Financial Times reported.
A government spokesman said Wylfa was one of many “potential sites” that could host nuclear projects.
Hitachi abandoned its plans there in January 2019.
An unnamed minister told the FT that “tentative negotiations” with Hitachi had already begun, but said a deal might not be reached until after a general election expected later this year.
Tom Greatrex, chief executive of the Nuclear Industry Association and Virginia Crosbie, MP for Ynys Môn both welcomed the talks.
These are my thoughts.
Where Is Wylfa?
This Google Map shows Anglesey.
Wylfa power station is near Wylfa Head at the top of the map, where they are indicated by the cluster of red arrows.
This Google Map shows the power station to a larger scale.
Note.
- The red arrow named Magnox marks the decommissioned Magnox power station.
- The topmost red arrow marks Wylfa Head.
- The rightmost red arrow marks Porth y Wylfa, which looks like a small harbour.
- On some maps the square building to the East of the power station is marked as Wylfa sub-station.
- There certainly appears to be an overhead transmission line leading South from the power station complex.
Virginia Crosbie, MP for Ynys Môn, also said this according to the BBC article.
The nuclear industry is unanimous that Wylfa is the best site in Europe for large-scale nuclear,” she said, adding that it would be “the largest inward investment” in Welsh history and “transformational” for the people of north-west Wales.
But I do wonder, if when you have cleared the Wylfa site leaving the sub-station, that it could be a site where renewables could come ashore and be fed into the grid.
Why Is Wylfa The Best Site In Europe For Large-Scale Nuclear?
Given the protests about putting new power transmission lines across Norfolk and Suffolk, I feel that Wylfa’s largest asset could be its high capacity connection to the UK’s grid.
According to the Wikipedia entry for Wylfa power station, this is said about Wylfa B.
Horizon Nuclear Power, originally an E.ON and RWE joint venture, bought by Hitachi in 2012, announced in 2009 intentions to install about 3,000 MWe of new nuclear plant at Wylfa. Horizon planned to build two advanced boiling water reactors (ABWRs) at a site to the south of the existing Wylfa station.
It would seem that the high capacity connection to the UK’s grid, is capable of handling a 3 GW power station at Wylfa, which could be very useful in the grand scheme of things.
This is also said in the Wikipedia entry for Wylfa power station.
On 4 April 2017, Horizon submitted a Site Licence Application to the Office for Nuclear Regulation. The scheme was extended to include a tunnel under the Menai Strait to carry the power cables to protect the conservation worth of the Strait and the Area of Outstanding Natural Beauty.
Horizon certainly seemed to try hard to get Wylfa B under construction.
As I said earlier, the Wylfa site could be an ideal site to connect offshore renewables to the grid.
Teesside Private SMR Nuclear Power Station To Be Built
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
An agreement has been reached to build a privately financed nuclear power station in Teesside.
These are the first three paragraphs.
Community Nuclear Power (CNP) has announced plans to install four small modular reactors (SMRs) in North Tees.
CNP said it aims to be up and running in ten years’ time and will supply “roughly a gigawatt of energy”.
With other similar power stations planned, hundreds of jobs are expected to be created in the north-east of England.
A CNP spokesperson said the four North Tees reactors will generate clean, always-on energy which will be used to help develop a green energy and chemical hub, also within the North Tees Group Estate, on the north bank of the River Tees near Stockton.
These are my thoughts.
The Westinghouse AP300™ SMR
This SMR has its own web page.
This is the sub-heading.
Only SMR based on Licensed, Operating & Advanced Reactor Technology
These paragraphs introduce the reactor.
The Westinghouse AP300™ Small Modular Reactor is the most advanced, proven and readily deployable SMR solution. Westinghouse proudly brings 70+ years of experience developing and implementing new nuclear technologies that enable reliable, clean, safe and economical sources of energy for generations to come.
Our AP1000® reactor is already proving itself every day around the globe. Currently, four units utilizing AP1000 technology are operating in China, setting performance records. Six more are under construction in China and one AP1000 reactor is operating at Plant Vogtle in Georgia while a second nears completion.
Our AP300 SMR leverages that operating experience, as well as tens of millions of hours on AP1000 reactor development.
Gain the benefits of the record-setting Westinghouse AP1000 PWR technology in a smaller power output to augment the backbone of your community energy system.
The AP300 SMR complements the AP1000 reactor for a cleaner energy mix, energy security, and grid flexibility and stabilization.
Westinghouse seem to have taken a very professional and scientifically correct approach and downsized something that works well.
Where Will The Reactors Be Built?
This is a paragraph from the BBC article.
Small reactors, built in a factory by the American power giant Westinghouse, will be transported to Seal Sands near Billingham, coming on stream in the early 2030s and going some way to providing part of the big rise in nuclear capacity the UK government wants to see by 2050.
This Google Map shows the mouth of the River Tees.
Note.
- The red arrow at the bottom of the map indicates the location of North Tees Group Estate.
- Follow the river to the North and a capitalised label indicating the position of Seal Sands can be seen.
This second Google Map shows the Seal Sands area in a larger scale.
There seems to be several spaces, where the reactors could be located.
Would It Be Safe To Locate A Nuclear Reactor Or Reactors In a Cluster Of Oil Refineries And/Or Chemical Plants?
Consider.
- In the 1970s, when I worked at ICI, there were companies like Westinghouse advocating nuclear steelmaking.
- We did discuss the concept a couple of times over coffee but no one, I worked with, ever looked at it officially or seriously, as far as I know.
- In addition to requiring large amounts of electricity, oil refineries and chemical plants often use a lot of steam.
- Nuclear reactors generate steam to produce electricity, so some could be diverted to oil refineries or chemical plants
- To decarbonise some processes might switch to hydrogen.
- In Westinghouse And Bloom Energy To Team Up For Pink Hydrogen, I talk about how to use a nuclear reactor to efficiently produce pink hydrogen.
It looks like for efficiency, building the various plant close together could be a good thing.
But is it safe?
I suspect the level of safety will be that of the least safe plant.
So provided all plants are designed to the highest standards, it should be OK, as nuclear plants, oil refineries and chemical plant don’t regularly explode.
The Donald C Cook Nuclear Plant
The Donald C Cook Nuclear Plant in Michigan is a 2.2 GW nuclear plant, that was built by Westinghouse and commissioned in the mid-1970s.
They were clients for Artemis, the project management system that I wrote.
Soon after the Three Mile Island accident on March 28th, 1979, I visited the Donald C Cook Nuclear Plant to see how they were coping with the aftermath of the accident.
I remember being told by the operators of the plant, who were American Electric Power, that as it was their only nuclear plant, they were going to do everything by the book and Artemis was helping them to do that.
Reading about the plant, which is now licenced to operate until 2034 for one reactor and 2037 for the other, it seems to have performed impeccably so far for nearly fifty years.
It is a credit to both Westinghouse, who built it and American Electric Power who own it.
Now that is what I call high-class engineering and I’d be happy to have a cluster of SMRs to the same standard in my back yard.
Sizewell B
I used to live a few miles from Sizewell B, which is another Westinghouse reactor.
- This is the Wikipedia entry for the power station.
- Sizewell B was based on a proven Westinghouse design.
- It seems to have performed well since it was commissioned in 1995.
It looks like it will be operating until 2055, which will make its working life similar to those of the reactors at the Donald C Cook Nuclear Plant.
Westinghouse And Hinckley Point C Compared
Consider.
- Sizewell B was built in approximately seven years.
- This compares well with the two units at the Donald C Cook Nuclear Plant, which took six and nine years respectively
- It looks like Hinckley Point C will take between twelve and fourteen years to build.
- Sizewell B and the two units at Donald C Cook Nuclear Plant seem to be looking at a sixty year operating lifetime.
- Sizewell has a rail connection and Hinckley Point does not.
- Sizewell B seems to have been signed off, when John Major was Prime Minister.
- Hinckley Pont C seems to have resulted from a government white paper when Gordon Brown was Prime Minister.
Westinghouse seem to design nuclear power stations, that can operate for a long period and can be built within a decade.
Westinghouse And Rolls-Royce
Consider.
- Rolls-Royce also have an SMR design.
- Rolls-Royce and Westinghouse are both world-class companies.
- Rolls-Royce have the advantage they are British.
- I also suspect, that both Westinghouse and Rolls-Royce will use the same subcontractors and sub-assembly manufacturers.
- The Rolls-Royce SMR has a power output of 470 MW.
- The Westinghouse SMR has a power output of 300 MW.
I suspect the choice between the two, will be like choosing between top-of-the-range British and American products.
Conclusion
I wonder why we ended up with an unproven new French design at Hinckley Point, when sitting in Suffolk was a traditional Westinghouse design, that was performing to its design specification?
But for the SMR, we need to buy the reactors, which are financially best for Britain. If Westinghouse choose to manufacture large sections in the UK, they could be the better bet, as I suspect, if SMRs are successful, we’ll be seeing exports from the UK.
South Korean Team To Develop SMR-Powered Ships
The title of this post is the same as that of this article on Neutron Bytes.
This is the introductory paragraph.
Nine South Korean organizations have signed a memorandum of understanding (MoU) to cooperate on the development and demonstration of ships and offshore systems powered with small modular reactors (SMRs). The partners will also develop marine systems and the production of hydrogen using molten salt reactors (MSRs).
These points are listed about nuclear-powered ships.
- Over 160 ships are powered by more than 200 small nuclear reactors.
- Most are submarines, but they range from icebreakers to aircraft carriers.
- In future, constraints on fossil fuel use in transport may bring marine nuclear propulsion into more widespread use.
- So far, exaggerated fears about safety have caused political restrictions on port access.
Note.
- When as a child, I used to watch the large container ships at Felixstowe, I thought then, that they could be nuclear-powered.
- One engineering lecturer at Liverpool University in the 1960s, was talking about nuclear-powered tunneling machines.
- Rolls-Royce to name just one company must have the reactor technology.
I just wonder, when the Korean President and his wife visited the UK, just before Christmas, that nuclear-powered ships were discussed.
RWE Acquires 4.2-Gigawatt UK Offshore Wind Development Portfolio From Vattenfall
The title of this post, is the same as that of this press release from RWE.
These three bullet points, act as sub-headings.
- Highly attractive portfolio of three projects at a late stage of development, with grid connections and permits secured, as well as advanced procurement of key components
- Delivery of the three Norfolk Offshore Wind Zone projects off the UK’s East Anglia coast will be part of RWE’s Growing Green investment and growth plans
- Agreed purchase price corresponds to an enterprise value of £963 million
These two paragraphs outline the deal.
RWE, one of the world’s leading offshore wind companies, will acquire the UK Norfolk Offshore Wind Zone portfolio from Vattenfall. The portfolio comprises three offshore wind development projects off the east coast of England – Norfolk Vanguard West, Norfolk Vanguard East and Norfolk Boreas.
The three projects, each with a planned capacity of 1.4 gigawatts (GW), are located 50 to 80 kilometres off the coast of Norfolk in East Anglia. This area is one of the world’s largest and most attractive areas for offshore wind. After 13 years of development, the three development projects have already secured seabed rights, grid connections, Development Consent Orders and all other key permits. The Norfolk Vanguard West and Norfolk Vanguard East projects are most advanced, having secured the procurement of most key components. The next milestone in the development of these two projects is to secure a Contract for Difference (CfD) in one of the upcoming auction rounds. RWE will resume the development of the Norfolk Boreas project, which was previously halted. All three Norfolk projects are expected to be commissioned in this decade.
There is also this handy map, which shows the location of the wind farms.
Note that there are a series of assets along the East Anglian coast, that will be useful to RWE’s Norfolk Zone development.
- In Vattenfall Selects Norfolk Offshore Wind Zone O&M Base, I talked about how the Port of Great Yarmouth will be the operational base for the Norfolk Zone wind farms.
- Bacton gas terminal has gas interconnectors to Belgium and the Netherlands lies between Cromer and Great Yarmouth.
- The cable to the Norfolk Zone wind farms is planned to make landfall between Bacton and Great Yarmouth.
- Sizewell is South of Lowestoft and has the 1.25 GW Sizewell B nuclear power station, with the 3.2 GW Sizewell C on its way, for more than adequate backup.
- Dotted around the Norfolk and Suffolk coast are 3.3 GW of earlier generations of wind farms, of which 1.2 GW have connections to RWE.
- The LionLink multipurpose 1.8 GW interconnector will make landfall to the North of Southwold
- There is also the East Anglian Array, which currently looks to be about 3.6 GW, that connects to the shore at Bawdsey to the South of Aldeburgh.
- For recreation, there’s Southwold.
- I can also see more wind farms squeezed in along the coast. For example, according to Wikipedia, the East Anglian Array could be increased in size to 7.2 GW.
It appears that a 15.5 GW hybrid wind/nuclear power station is being created on the North-Eastern coast of East Anglia.
The big problem is that East Anglia doesn’t really have any large use for electricity.
But the other large asset in the area is the sea.
- Undersea interconnectors can be built to other locations, like London or Europe, where there is a much greater need for electricity.
- In addition, the UK Government has backed a consortium, who have the idea of storing energy by using pressurised sea-water in 3D-printed concrete hemispheres under the sea. I wrote about this development in UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind.
A proportion of Russian gas in Europe, will have been replaced by Norfolk wind power and hydrogen, which will be given a high level of reliability from Suffolk nuclear power.
I have some other thoughts.
Would Hydrogen Be Easier To Distribute From Norfolk?
A GW-range electrolyser would be feasible but expensive and it would be a substantial piece of infrastructure.
I also feel, that placed next to Bacton or even offshore, there would not be too many objections from the Norfolk Nimbys.
Hydrogen could be distributed from the site in one of these ways.
- By road transport, as ICI did, when I worked in their hydrogen plant at Runcorn.
- I suspect, a rail link could be arranged, if there was a will.
- By tanker from the Port of Great Yarmouth.
- By existing gas interconnectors to Belgium and the Netherlands.
As a last resort it could be blended into the natural gas pipeline at Bacton.
In Major Boost For Hydrogen As UK Unlocks New Investment And Jobs, I talked about using the gas grid as an offtaker of last resort. Any spare hydrogen would be fed into the gas network, provided safety criteria weren’t breached.
I remember a tale from ICI, who from their refinery got a substantial amount of petrol, which was sold to independent petrol retailers around the North of England.
But sometimes they had a problem, in that the refinery produced a lot more 5-star petrol than 2-star. So sometimes if you bought 2-star, you were getting 5-star.
On occasions, it was rumoured that other legal hydrocarbons were disposed of in the petrol. I was once told that it was discussed that used diluent oil from polypropylene plants could be disposed of in this way. But in the end it wasn’t!
If hydrogen were to be used to distribute all or some of the energy, there would be less need for pylons to march across Norfolk.
Could A Rail Connection Be Built To The Bacton Gas Terminal
This Google Map shows the area between North Walsham and the coast.
Note.
- North Walsham is in the South-Western corner of the map.
- North Walsham station on the Bittern Line is indicated by the red icon.
- The Bacton gas terminal is the trapezoidal-shaped area on the coast, at the top of the map.
ThisOpenRailwayMap shows the current and former rail lines in the same area as the previous Google Map.
Note.
- North Walsham station is in the South-West corner of the map.
- The yellow track going through North Walsham station is the Bittern Line to Cromer and Sheringham.
- The Bacton gas terminal is on the coast in the North-East corner of the map.
I believe it would be possible to build a small rail terminal in the area with a short pipeline connection to Bacton, so that hydrogen could be distributed by train.
There used to be a branch line from North Walsham station to Cromer Beach station, that closed in 1953.
Until 1964 it was possible to get trains to Mundesley-on-Sea station.
So would it be possible to build a rail spur to the Bacton gas terminal along the old branch line?
In the Wikipedia entry for the Bittern Line this is said.
The line is also used by freight trains which are operated by GB Railfreight. Some trains carry gas condensate from a terminal at North Walsham to Harwich International Port.
The rail spur could have four main uses.
- Taking passengers to and from Mundesley-on-Sea and Bacton.
- Collecting gas condensate from the Bacton gas terminal.
- Collecting hydrogen from the Bacton gas terminal.
- Bringing in heavy equipment for the Bacton gas terminal.
It looks like another case of one of Dr. Beeching’s closures coming back to take a large chunk out of rail efficiency.
Claire Coutinho And Robert Habeck’s Tete-a-Tete
I wrote about their meeting in Downing Street in UK And Germany Boost Offshore Renewables Ties.
- Did Habeck run the RWE/Vattenfall deal past Coutinho to see it was acceptable to the UK Government?
- Did Coutinho lobby for SeAH to get the contract for the monopile foundations for the Norfolk Zone wind farms?
- Did Coutinho have a word for other British suppliers like iTMPower.
Note.
- I think we’d have heard and/or the deal wouldn’t have happened, if there had been any objections to it from the UK Government.
- In SeAH To Deliver Monopiles For Vattenfall’s 2.8 GW Norfolk Vanguard Offshore Wind Project, I detailed how SeAH have got the important first contract they needed.
So it appears so far so good.
Rackheath Station And Eco-Town
According to the Wikipedia entry for the Bittern Line, there are also plans for a new station at Rackheath to serve a new eco-town.
This is said.
A new station is proposed as part of the Rackheath eco-town. The building of the town may also mean a short freight spur being built to transport fuel to fire an on-site power station. The plans for the settlement received approval from the government in 2009.
The eco-town has a Wikipedia entry, which has a large map and a lot of useful information.
But the development does seem to have been ensnared in the planning process by the Norfolk Nimbys.
The Wikipedia entry for the Rackheath eco-town says this about the rail arrangements for the new development.
The current rail service does not allow room for an extra station to be added to the line, due to the length of single track along the line and the current signalling network. The current service at Salhouse is only hourly during peak hours and two-hourly during off-peak hours, as not all trains are able to stop due to these problems. Fitting additional trains to this very tight network would not be possible without disrupting the entire network, as the length of the service would increase, missing the connections to the mainline services. This would mean that a new 15-minute shuttle service between Norwich and Rackheath would have to be created; however, this would interrupt the main service and cause additional platforming problems. Finding extra trains to run this service and finding extra space on the platforms at Norwich railway station to house these extra trains poses additional problems, as during peak hours all platforms are currently used.
In addition, the plans to the site show that both the existing and the new rail station, which is being built 300m away from the existing station, will remain open.
. As the trains cannot stop at both stations, changing between the two services would be difficult and confusing, as this would involve changing stations.
I feel that this eco-town is unlikely to go ahead.
Did RWE Buy Vattenfall’s Norfolk Zone To Create Green Hydrogen For Europe?
Consider.
- Vattenfall’s Norfolk Zone is a 4.2 GW group of wind farms, which have all the requisite permissions and are shovel ready.
- Bacton Gas terminal has gas pipelines to Europe.
- Sizewell’s nuclear power stations will add security of supply.
- Extra wind farms could be added to the Norfolk Zone.
- Europe and especially Germany has a massive need for zero-carbon energy.
The only extra infrastructure needing to be built is the giant electrolyser.
I wouldn’t be surprised if RWE built a large electrolyser to supply Europe with hydrogen.
Is Sizewell C Needed?
I am generally pro-nuclear, but I am not sure if building a large nuke at Sizewell is the right action.
Consider.
- East Anglia has 3114 MW of offshore wind in operation.
- East Anglia has 6772 MW of offshore wind under construction, with Contracts for Difference or proposed.
- Vattenfall are considering abandoning development of their large wind farms off the Norfolk coast, which are proposed to have a capacity of 3196 MW.
- If the two Vattenfall wind farms don’t get built, it is likely that East Anglia will have around 6700 MW of offshore wind capacity.
- Sizewell C has a proposed nameplate capacity of 3260 MW. Some might argue, that to back up East Anglia’s offshore wind power, it needs to be larger!
- Norfolk and Suffolk no large electricity users, so are Vattenfall finding they have a product no one wants to buy.
- National Grid is developing four interconnectors to bring power from Scotland to the Eastern side of England, which will back up wind power in the East with the massive Scottish pumped storage, that is being developed.
- National Grid and their Dutch equivalent; TenneT are developing LionLink to connect the UK and the Netherlands to clusters of wind farms between our countries in the North Sea.
- Kent and East Anglia have several gas and electric interconnectors to Europe.
- Sizewell is well-connected to England’s grid.
These are my thoughts.
Energy Storage At Sizewell
Consider.
- Sizewell is well connected to the grid.
- It has the sea on one side.
- It could easily be connected to the large offshore wind farms, thirty miles out to sea.
If large energy storage could be built on the Sizewell site or perhaps under the sea, then this energy could be recovered and used in times of low wind.
Perhaps the technology of the STORE Consortium, which I discussed in UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind, could be used.
In this system, energy is stored in 3D-printed concrete hemispheres under the sea.
A Small Nuclear Reactor Cluster At Sizewell
Rolls-Royce are proposing that their small modular reactors will have a capacity of 470 MW.
Perhaps a cluster of seven small modular reactors at Sizewell, with a building schedule matched to the need to back up wind farms would be better and easier to finance.
I also feel a cluster of SMRs would have less risk and would be less likely to be delayed.
Where Is Generating Capacity Needed In The UK?
These areas already have large amounts of offshore wind in operation or proposed to be built before 2030.
- Celtic Sea
- North Wales
- Liverpool Bay
- Cumbria
- Scotland
- Scotland’s Offshore Islands
- North East England
- Humberside
- Lincolnshire
- East Anglia
- Thames Estuary
- Kent
- Sussex
Amongst the back up for these wind farms, there are only two modern nuclear stations; Sizewell B and the still-to-open Hinckley Point C.
If you look at a map of England and its power generation, there is a tremendous gap of capacity South of a line between Hinckley Point and Brighton, with little or no offshore wind and no nuclear.
There is probably a need for a large nuke near Weymouth.
Alternatively, perhaps several SMRs could be built underneath places like Salisbury Plain, Dartmoor and Exmoor!
Conclusion
We probably need the nuclear electricity from another Hinckley Point C-sized nuclear power station, so that we have adequate back-up for offshore wind.
But I am not sure that Sizewell is the right place to build it.
Ultra Safe Nuclear, Hyundai Engineering, SK Ecoplant Sign MOU For Clean Hydrogen Production
The title of this post, is the same as that of this press release from Ultra Safe Nuclear Corporation.
These are the first two paragraphs.
Ultra Safe Nuclear Corporation, the U.S.-based global leader in the deployment of fourth-generation gas-cooled microreactors, Hyundai Engineering (Representative Director Hong Hyun-sung) and SK ecoplant (Representative Director Park Kyung-il) are teaming up to conduct research and development for carbon-free hydrogen production. The three companies signed an MOU on Thursday, April 20th for the construction of a “Hydrogen Micro Hub” at the SK ecoplant headquarters in Seoul’s Jongno-gu.
The “Hydrogen Micro Hub” is a facility that produces hydrogen by applying a high-temperature electrolysis process of solid oxide electrolysis cells (SOEC) to the electricity and high-temperature steam generated by USNC’s Micro-Modular™ Reactor (MMR®). This is a carbon-free hydrogen production method that extracts hydrogen by decomposing water with electricity generated from nuclear power.
Ultra Safe Nuclear Corporation has a web site.
- Ultra Safe Nuclear Corporation, is a U.S. corporation headquartered in Seattle.
- Canada appears to be deeply involved.
- Innovate UK appears to have dished out a grant.
- They appear to have sold five of their MMRs.
The company could be a serious competitor in the market for small modular nuclear reactors.
Low Carbon Construction Of Sizewell C Nuclear Power Station
Sizewell C Nuclear Power Station is going to be built on the Suffolk Coast.
Wikipedia says this about the power station’s construction.
The project is expected to commence before 2024, with construction taking between nine and twelve years, depending on developments at the Hinkley Point C nuclear power station, which is also being developed by EDF Energy and which shares major similarities with the Sizewell plant.
It is a massive project and I believe the construction program will be designed to be as low-carbon as possible.
High Speed Two is following the low-carbon route and as an example, this news item on their web site, which is entitled HS2 Completes Largest Ever UK Pour Of Carbon-Reducing Concrete On Euston Station Site, makes all the right noises.
These three paragraphs explain in detail what has been done on the Euston station site.
The team constructing HS2’s new Euston station has undertaken the largest ever UK pour of Earth Friendly Concrete (EFC) – a material that reduces the amount of carbon embedded into the concrete, saving over 76 tonnes of CO2 overall. John F Hunt, working for HS2’s station Construction Partner, Mace Dragados joint venture, completed the 232 m3 concrete pour in early September.
The EFC product, supplied by Capital Concrete, has been used as a foundation slab that will support polymer silos used for future piling works at the north of the Euston station site. Whilst the foundation is temporary, it will be in use for two years, and historically would have been constructed with a more traditional cement-based concrete.
The use of the product on this scale is an important step forward in how new, innovative environmentally sustainable products can be used in construction. It also helps support HS2’s objective of net-zero construction by 2035, and achieve its goal of halving the amount of carbon in the construction of Britain’s new high speed rail line.
Note.
- Ten of these slabs would fill an Olympic swimming pool.
- I first wrote about Earth Friendly Concrete (EFC) in this post called Earth Friendly Concrete.
- EFC is an Australian invention and is based on a geopolymer binder that is made from the chemical activation of two recycled industrial wastes; flyash and slag.
- HS2’s objective of net-zero construction by 2035 is laudable.
- It does appear that this is a trial, but as the slab will be removed in two years, they will be able to examine in detail how it performed.
I hope the Sizewell C project team are following High Speed Two’s lead.
Rail Support For Sizewell C
The Sizewell site has a rail connection and it appears that this will be used to bring in construction materials for the project.
In the January 2023 Edition of Modern Railways, there is an article, which is entitled Rail Set To Support Sizewell C Construction.
It details how sidings will be built to support the construction, with up to four trains per day (tpd), but electrification is not mentioned.
This is surprising to me, as increasingly, big construction projects are being managed to emit as small an amount of carbon as possible. Sizewell C may be an isolated site, but in Sizewell B, it’s got one of the UK’s biggest independent carbon-free electricity generators a couple of hundred metres away.
The writer of the Modern Railways article, thinks an opportunity is being missed.
I feel the following should be done.
- Improve and electrify the East Suffolk Line between Ipswich and Saxmundham Junction.
- Electrify the Aldeburgh Branch Line and the sidings to support the construction or agree to use battery-electric or hydrogen zero-carbon locomotives.
Sizewell C could be a superb demonstration project for low-carbon construction!
Sizewell C Deliveries
Sizewell C will be a massive project and and will require a large number of deliveries, many of which will be heavy.
The roads in the area are congested, so I suspect rail is the preferred method for deliveries.
We already know from the Modern Railways article, that four tpd will shuttle material to a number of sidings close to the site. This is a good start.
Since Sizewell A opened, trains have regularly served the Sizewell site to bring in and take out nuclear material. These occasional trains go via Ipswich and in the last couple of years have generally been hauled by Class 88 electro-diesel locomotives.
It would be reasonable to assume that the Sizewell C sidings will be served in the same manner.
But the route between Westerfield Junction and Ipswich station is becoming increasingly busy with the following services.
- Greater Anglia’s London and Norwich services
- Greater Anglia’s Ipswich and Cambridge services
- Greater Anglia’s Ipswich and Felixstowe services
- Greater Anglia’s Ipswich and Lowestoft services
- Greater Anglia’s Ipswich and Peterborough services
- Freight services serving the Port of Felixstowe, which are expected to increase significantly in forthcoming years.
But the Modern Railways article says this about Saxmundham junction.
Saxmundham junction, where the branch meets the main line, will be relaid on a slightly revised alignment, retaining the existing layout but with full signalling giving three routes from the junction protecting signal on the Down East Suffolk line and two in the Down direction on the bidirectional Up East Suffolk line. Trap points will be installed on the branch to protect the main line, with the exit signal having routes to both running lines.
Does the comprehensive signalling mean that a freight train can enter or leave the Sizewell sidings to or from either the busy Ipswich or the quieter Lowestoft direction in a very safe manner?
I’m no expert on signalling, but I think it does.
- A train coming from the Lowestoft direction needing to enter the sidings would go past Saxmundham junction on the Up line. Once clear of the junction, it would stop and reverse into the branch.
- A train coming from the Ipswich direction needing to enter the sidings would approach in the wrong direction on the Up line and go straight into the branch.
- A train leaving the sidings in the Lowestoft direction would exit from the branch and take the Up line until it became single track. The train would then stop and reverse on to the Down line and take this all the way to Lowestoft.
- A train leaving the sidings in the Ipswich direction would exit from the branch and take the Up line all the way to Ipswich.
There would need to be ability to move the locomotive from one end to the other inside the Sizewell site or perhaps these trains could be run with a locomotive on both ends.
The advantage of being able to run freight trains between Sizewell and Lowestoft becomes obvious, when you look at this Google Map, which shows the Port of Lowestoft.
Note.
- The Inner Harbour of the Port of Lowestoft.
- The East Suffolk Line running East-West to the North of the Inner Harbour.
- Lowestoft station at the East side of the map.
I doubt it would be the most difficult or expensive of projects to build a small freight terminal on the North side of the Inner Harbour.
I suspect that the easiest way to bring the material needed to build the power station to Sizewell would be to do the following.
- Deliver it to the Port of Lowestoft by ship.
- Tranship to a suitable shuttle train for the journey to the Sizewell sidings.
- I estimate that the distance is only about 25 miles and a battery or hydrogen locomotive will surely be available in the UK in the next few years, that will be able to provide the motive power for the return journey.
In The TruckTrain, I wrote about a revolutionary freight concept, that could be ideal for the Sizewell freight shuttle.
In addition, there is no reason, why shuttle trains couldn’t come in from anywhere connected to the East Suffolk Line.
Zero-Carbon Construction
Sizewell C could be the first major construction site in the UK to use electricity rather than diesel simply because of its neighbour.
Conclusion
I shall be following the construction methods at Sizewell C, as I’m fairly sure they will break new ground in the decarbonisation of the Construction industry.
