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.

Ørsted’s Earnings from Operational Offshore Wind Farms Up 20 Pct

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

Ørsted has reported 2024 earnings from its operational offshore wind farms of DKK 23.8 billion (approximately EUR 3.2 billion), up by 20 per cent compared to 2023.

And this is the introductory paragraph.

The global offshore wind developer said on 6 February the increase was mainly due to the ramp-up of generation at Greater Changhua 1 and 2a offshore wind project in Taiwan, South Fork in the US, and Gode Wind 3 in Germany, as well as higher wind speeds, higher pricing of the inflation-indexed CfDs and green certificates. The increase in 2024 was dampened by lower availability, according to the company.

I don’t think Trummkopf would get those sort of returns, if he invested any of his own money in his plan for the “Riviera of the Middle East”.

Although my American friend ; Jack and his family enjoyed themselves in the Lebanon in the 1960s, when he lectured at the American University of Beirut.

On the other hand this article in The Times is entitled Trump’s Gaza Plan Watered Down Amid Backlash From Allies.

Show Me The Way To Motspur Park

A few days ago, I saw on a web site, that Motspur Park station had been made step-free.

I tried to go yesterday, but I made a big mistake – I started from Moorgate station and intended to use the Waterloo and City Line to get to Waterloo station, from where I could get a direct train.

But after taking forever to walk between the Northern and Waterloo and City Line at Bank station, I arrived at Waterloo station, too late to get to Motspur Park station before dark.

Today, I looked up Transport for London’s Journey Planner and it told me to do the following.

  • Walk to Newington Green Road, which is rather a long walk for my 77-year-old legs.
  • Get a 341 bus to Manor House Station.
  • Get a Piccadilly Line train to Finsbury Park station.
  • Get a Victoria Line train to Vauxall station. This is a cross-platform interchange.
  • Walk to Vauxall National Rail station.
  • Get a South Western Railway train to Motspur Park station.

Note.

  1. Normally, I would use a variation of this route and take a 141 bus from the corner of my road to Manor House station.
  2. But due to road works, the 141 is not stopping near my house, so I have no easy way to get to Manor House station.
  3. But in some ways to start a journey to the South-West, by going North to Manor House station is a bit silly.
  4. This detour is caused because neither the Victoria or Piccadilly Lines have an exchange station with the Lizzie Line.

If the 141 bus were running, I’d take that to Moorgate, then take Lizzie to Bond Street and the Jubilee Line to Waterloo for a train to Motspur Park.

I would have taken this route yesterday from Moorgate, but I was advised otherwise by a station guy at Moorgate.

In the end today, I took a bus to King’s Cross and got the Victoria Line from there.

I took these pictures of the elderly Class 455 train en route.

Although at forty, it was still in good condition.

I took these pictures of the new bridge at Motspur Park station.

Note.

  1. The two-button lift controls. Would they be faster if single-button?
  2. I am surprised that solar roofs weren’t fitted as at Denmark Hill station.
  3. The station must be the only station in London with an island platform and three lifts. See Picture 6.
  4. PPicture 6 also clearly shows a ticket machine on the platform, which serves both entrances.

It certainly looks to be a comprehensive job well done.

The Future Of Drax Power Station

Drax power station is not liked by a lot of environmentalists.

I have been thinking about the future of the power station and the public company that owns it.

Drax power station has a nameplate capacity of around 2.5 GW running on biomass.

It also will be the Southern end of EGL2, which will be an undersea electricity 2 GW superhighway distributing Scottish wind power from Peterhead in Scotland. So the dreaded biomass hated by certain groups will be relegated from the Premier League of electricity generation and replaced by Scottish wind.

As reported in various publications, Drax has signed a deal in the US, so that the biomass can be used for the production of sustainable aviation fuel (SAF)

To my mind, the Drax site could be an ideal one for one or more small modular nuclear reactors.

  • The large Drax site has been producing electricity for 52 years.
  • In 1986, the site produced nearly 4 GW of electricity.
  • I would suspect that the substations on the site could be enlarged to distribute 4 GW of electricity.
  • EGL2 will bring in 2 GW of Scottish wind-generated electricity.
  • The site has excellent rail connections.
  • The site has twelve cooling towers and is encircled by the River Ouse.
  • Could all this water be used for cooling the small modular nuclear reactors.

I believe that perhaps three small modular nuclear reactors could be built on the Drax site to backup EGL2 and bring a reliable source of sustainable power to Yorkshire.

Drax is also only about forty miles from the vast hydrogen stores at Aldbrough and Rough, so if Drax needed, if could use excess electricity to create hydrogen for storage.

SSE is consulting on a 1+ GW hydrogen power station at Keadby, so perhaps Drax should have a similar hydrogen power station on its site?

Are Rolls-Royce Converting The World To Sussainable Fuels?

Rolls-Royce are certainly up to something.

  • Versions of all their diesel and aero engines appear to be able to or will be able to run on hydrogen, SAF, HVO and other exotic zero or low-carbon fuels.
  • They are replacing the engines on the USAF B 52s with new American-built Rolls-Royce engines, that can run on hydrogen.
  • They are working with easyJet on zero-carbon engines.
  • They are developing the UltraFan, which promises to be the most frugal turbofan engine ever. Will all long-distance wide-bodies end up Rolls-Royce powered?
  • They have developed a frugal engine for business jets that can run on any fuel.
  • Rolls-Royce have also developed a 2.5 MW electric generator based on the engine of a Super Hercules. This level of power is what you need for a railway locomotive.
  • Are they building a retrofit for all the diesel-electric railway locomotives of the world, which runs on hydrogen?

Some of these developments could be moving from diesel, jet-fuel and SAF to hydrogen. Others will just reduce the amount of fuel needed.

I just can’t get the image of an iconic B 52, with RR on the side of the engines out of my mind.

But all of these developments seem to have one aim in mind. – To reduce the amount of aircraft and other large vehicles that have to run on standard jet fuel, diesel, SAF or HVO.

This will mean that long-distance air travel, which will be the most difficult to decarbonise will be able to use SAF and other exotic fuels made from renewable sources.

UK Wind Risks ‘Exponentially Rising’ Curtailment Without Energy Storage

The title of this post, is the same as that of this article on Recharge.

This is the sub-heading.

UK liquid battery pioneer Highview Power is working with renewable energy giant Orsted on plan to store excess power from its Hornsea offshore wind projects

This is the introductory paragraph.

The UK wind sector faces “exponentially” increasing curtailment of assets without a rapid rollout of energy storage, says the chief of liquid battery pioneer Highview Power, which is working with Orsted on a project to store excess offshore wind power.

The article also states that according to Octopus Energy, this cost could have been as high as a billion pounds last year.

In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I described how Ørsted were planning to build a large BESS near the Swardeston substation in Norfolk, where the Hornsea 3 wind farm will connect to the grid.

Have Ørsted  decided to put a Highview Power battery on the Swardeston site, as it can be a bigger battery, as Highview Power talk about 200MW/2.5GWh capacity batteries on the projects page of the web site?

Highview also say this about co-operation with Ørsted on that page.

Highview Power and Ørsted’s joint study shows that the co-location of LAES with Ørsted’s offshore wind offers a step forward in reducing wind curtailment, and helping to move to a more flexible, resilient zero carbon grid.

The words are accompanied by pictures of a smart gas storage site, which shows four of the largest tanks, that might be used to store LNG.

In Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?, I estimated that one of the largest LNG tanks could hold about a GWh of energy.

So Highview Power’s visualisation  on their project page would be a 4 GWh battery.

ZeroAvia Receives FAA G-1 For 600kW Electric Propulsion System

The title of this post, is the same as that of this press release from ZeroAvia.

This is the sub-heading.

Issue paper confirms basis of certification and provides clear pathway to certification of the company’s first commercial product

These are two introductory paragraphs.

ZeroAvia today announced that it has reached consensus on the Certification Basis relating to its 600kW electric propulsion system (EPS) with the Federal Aviation Administration (FAA), having received a G-1 Issue Paper (stage 2) and formally confirmed agreement with its contents.

The G-1 represents a key milestone on the journey towards final certification of the company’s EPS with the U.S. regulator, and also on its path to certifying its first full hydrogen-electric powertrain (of which the EPS is a core system) with the UK Civil Aviation Authority. The issue paper designates the applicable airworthiness regulations specific for ZeroAvia’s EPS, allowing the company to validate its design requirements.

Zero-carbon aviation just got a little bit closer, as when it is certified, the 600 KW electric propulsion system (EPS) will be able to be retrofitted to aircraft like the Cessna Caravan.

This is a Cessna Grand Caravan, that I flew in on holiday in Kenya.

I can see a lot of zero-carbon Caravans flying around the tropics on hydrogen generated by a nifty piece of hydrogen gubbins powered by the sun.

Especially, as over three thousand have been built.

I’ve Just Come Across Avnos

I feel we should take into account any possibilities of second use of oil or gas structures, that once held hydrocarbons.

An article in a magazine called Carbon Herald pointed me to a company called Avnos, who are developing Direct Air Capture of carbon dioxide out of the atmosphere. If systems like that of Avnos do work, we may need somewhere to put the carbon dioxide.

 

Centrica are storing the hydrogen in the Rough gas field, which was previously used for storing natural gas and now some depleted gas fields are being used to store captured carbon dioxide.

 

On the subject of carbon capture, Avnos do it differently, in that for every tonne of CO2, they capture from the air, they capture five tonnes of distilled water. And they do it without using any heat.

This is their web site.

This is their mission statement on the front page of the web site. There is also a video.

Carbon Negative. Water Positive

Avnos is commercializing the most advanced technology in the Direct Air Capture of CO2

Our proprietary Hybrid Direct Air Capture (HDAC) solution inverts the water paradigm in DAC, producing water, eliminating heat consumption and reducing costs compared to other forms of DAC.

It sounds too good to be true!

But I have experience of the positive financial results of fluid dynamics in this area.

Thirty years ago, two guys approached me with an idea for an aerosol valve that used nitrogen as a propellant.

At the time, I lived in the house, where Osborne Reynolds, the great Victorian fluid dynamicist of Reynold’s number fame had been brought up.

The guys succeeded and the device was sold on to J & J.

They were then asked to develop a metered dose inhaler for asthma drugs, which is now sold as Respimat, which is sold by Boehringer Ingelheim.

Afterwards, I researched Reynolds at Manchester University, where he was the first Professor of Engineering and I found that he had done some marvelous things with fluids. He was a true genius and undergraduates are still taught on his Victorian apparatus.

I suspect that Avnos may have been exploring in the same area and are using another of Reynold’s useful properties.

Paddington And Minehead By Train

Two projects announced in the last six months may make this a possibility.

  • FirstGroup’s Paddington and Paignton Service
  • The West Somerset Tidal Lagoon

Neither project has the full permissions it needs, but if Lumo do stop at Taunnton and the West Somerset Tidal Lagoon is built, if could open up an interesting possibility.

In Thoughts On Lumo’s Proposed Paddington And Paignton Service, I stated that a train could take two hours between  Paddington and Taunton, if it went for a fast non-stop run to Bath Spar station.

In MP Pushes For Tidal Lagoon In Bristol Channel, I said this.

I believe that for the lagoon project to be complete, the West Somerset Railway needs to be turned into a fully-operational branch line between Minehead and Taunton to improve access for residents, visitors and workers to Minehead and other places in West Somerset.

Surely, with a quick change of train, passengers could be in Minehead thirty minutes after arriving at Taunton.

In recent years several new branch lines have open in the UK and been given time to attract new passengers.

  • The Borders Railway to Tweedbank
  • Merseyrail to Headbolt Lane
  • The Northumberland Line to Ashington
  • ScotRail to Leven.
  • The Dartmouth Line to Okehampton

None appear to be in any danger of being closed.

I very much feel, that if the West Somerset Railway, ran a full service between Minehead and Taunton, it would follow the same pattern.

British Buses For British Bottoms

Occasionally, I catch the 153 bus, as it goes between the Leon, where I often go for breakfast, and the William Harvey Heart Centre, where I volunteer as a lab-rat.

Lately, I’ve noticed that the route is being run by new Wrightbus GB Kite single-decker battery-electric buses.

This morning I had a ride.

Note.

  1. The buses are battery-electric.
  2. This page is the bus’s home page.
  3. This bus is the short 10.2 metre long version.
  4. It was certainly a well-built, smooth-riding and comfortable bus, that was approved by my sensitive British bottom.

This Press Release from Wrightbus is entitled Wrightbus Sets Sights On Further European Expansion After Hydrogen Buses Land In Germany.

This is the sub-heading.

Leading zero-emission bus pioneer Wrightbus has announced plans for further expansion into Europe following the arrival of a landmark hydrogen bus order into Germany.

These are the first three paragraphs.

All of the 31 buses for operator Regionalverkehr Köln Gmbh (RVK) are now in situ – the first ever Wrightbus vehicles on European soil – with testing underway before the fleet goes into service across the Cologne region.

Named the fastest-growing bus manufacturer in Europe, Wrightbus has enjoyed a remarkable year. Alongside further hydrogen bus deals for Saarbahn, Vestische, Cottbus and West Verkehr, and the opening of a new European service centre in Bruhl, Wrightbus is also hiring staff to supply buses to France and Benelux.

In October, it also signed a landmark deal worth up to half-a-billion pounds to supply more than 1,000 buses to operator Go-Ahead over the next three years – 90 per cent of which will be zero-emission.

The press release says that deals are possible in France and Benelux.
