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.
- Normally, I would use a variation of this route and take a 141 bus from the corner of my road to Manor House station.
- 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.
- But in some ways to start a journey to the South-West, by going North to Manor House station is a bit silly.
- 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.
- The two-button lift controls. Would they be faster if single-button?
- I am surprised that solar roofs weren’t fitted as at Denmark Hill station.
- The station must be the only station in London with an island platform and three lifts. See Picture 6.
- 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.
