UK Space Agency And NNL Work On World’s First Space Battery Powered By British Fuel
The title of this post, is the same as that of this press release from the UK Government.
This is the sub-title.
The UK Space Agency and the National Nuclear Laboratory (NNL) are to collaborate on the world’s first space battery powered by Americium-241.
And these three paragraphs outline the project.
This work, commissioned and funded by the UK Space Agency from NNL, will be delivered in a new £19 million laboratory in Cumbria equipped with next-generation equipment and technology. It will deliver a sovereign supply of fuel for space batteries in the context of a global shortage, enabling the UK and its partners to pursue new space science and exploration missions.
Creating new highly-skilled jobs in the North West of England, it will drive innovation in radiochemistry and separations science and open a new market for the UK space sector.
Atomic space batteries, also known as Radioisotope Power Systems (RPSs), release heat as the radioactivity within them decays. The heat can be used directly to prevent spacecraft from freezing and it can be converted into electricity to power onboard systems. The batteries go on working for decades, without need for maintenance over the many years in which a spacecraft could be travelling.
These two paragraphs explain, why there is a need for a new type of atomic space batteries.
Considered ‘mission critical technologies’ by space agencies in the UK and around the world, all the Apollo missions had an atomic battery in tow, as has every rover that has gone to Mars. Until now, these have been powered by Plutonium-238, a radioisotope produced only in the US, where supply is limited, and Russia, so an alternative is urgently needed.
NNL, the UK’s national laboratory for nuclear fission, has been working on this endeavor since 2009, when its researchers first discovered that Americium-241, an alternative to Plutonium-238, is produced during the radioactive decay of used fuel from nuclear reactors and that it emits power for over 400 years.
With the supply plentiful – the new laboratory is being opened at NNL’s flagship Central Laboratory on the Sellafield site, home to the largest resource of Americium-241 available for extraction in the world – the new collaboration will turn a proven scientific concept into a fully-realised technology. It will be operational within the next four years and is expected to be first used on the European Space Agency’s Argonaut mission to the Moon and for future missions into deep space.
It would appear that Americium-241 has several advantages over Plutonium-238.
- Plutonium-238 has supply problems
- Who in their right mind, would buy a product like this from Russia or China?
- The batteries have a life of 400 years.
- There is plenty of suitable nuclear waste at Sellafield, from which Americium-241 can be extracted.
It looks like the first batteries could also be available in four years.
Aunt Margery
My late wife; C’s Aunt Margery was a lady, who needed a pacemaker. I seem to remember that after several of her pacemakers had run out of power and were replaced, and eventually she was fitted with a nuclear-powered pacemaker in the 1970s or 1980s.
This page on the Stanford University web site is entitled The History Of Nuclear Powered Pacemakers. It was written by Matthew DeGraw.
Many of these pacemakers in the 1960s and 1970s, were powered by Plutonium-238.
The last paragraph is entitled The Rise Of Lithium Battery Pacemakers And Fall Of Nuclear Pacemakers, where this is said.
Despite the often longer life-expectancies, nuclear pacemakers quickly became a part of the past when lithium batteries were developed. Not only did the technology improve, allowing for lighter, smaller, and programmable pacemakers, but doctors began to realize that this excessive longevity of nuclear pacemakers was excessive. Lithium pacemakers often last 10-15 years allowing for doctors to check in on their patients and replace either the batteries or the pacemakers themselves with new and improved technology as it is develops in those 10-15 year spans. While there are still several remaining patients with nuclear-powered pacemakers functioning in their bodies, it is likely that in the next few decades as these patients pass away, so will the once promising nuclear pacemakers.
Would the use of Americium-241 to power a nuclear pacemaker transform the economics of these devices?
I wonder, if there’s a cardiologist out there, who by chance reads this blog, who could answer my question!
Funding Available For Rail Construction Innovation Projects
The title of this post, is the same as that of this article on Railway Gazette.
These are the two introductory paragraphs.
Innovators from across the UK are being invited to submit proposals for the Innovation in Railway Construction Competition, which is making £7·44m available for ideas which could be tested at the Global Centre of Rail Excellence in South Wales.
The competition is being run by Innovate UK with GCRE and the Department for Business, Energy & Industrial Strategy.
£7.44m doesn’t seem much, but it is only for feasibility studies, as the article explains.
Entries for the first phase close at 12.00 on December 14, with funding available for feasibility studies of up to £25 000. This would be followed by an invite-only phase two, with successful first phase projects able to develop and demonstrate their innovations.
As Innovate UK keeps coming up with these competitions, they must be judged to be worthwhile.
Do they use the same technique in areas like Health and the NHS? If not, why not!
I Can Now See Why A Big Pharma Company Liked My Software Daisy
Yesterday, I went to a seminar about medical research.
There was a presentation, where data in several dimensions was shown and the data was crying out for a Daisy Chart.
A Daisy Chart
This chart is a very simple presentation of telephone data, but I can imagine arcs showing factors like Dose, Blood Pressure, Sex, Patient Satisfaction etc.
Note.
- This chart is what I call a Day of the Week/Hour of the Day chart, which is a powerful way of looking at any time-based data, like faults or A & E arrivals.
- You can click on the nodes and links of the chart to access the data underneath. So if you wanted all female patients with high blood pressure in a separate Excel spreadsheet, this is possible with a couple of clicks.
- The charts can also be clipped from the screen and inserted into reports.
Daisy was used by one Big Pharma company twenty years ago and after yesterday’s presentation, I can understand, why they used it.
The seminar changed my mind about my attitude to Daisy and I got rather fired up about its possibilities.
China Covid: Chinese TV Censors Shots Of Maskless World Cup Fans
The title of this post, is the same as that of this article on the BBC.
These two paragraphs outline China’s censorship of the World Cup.
The phrase “football is nothing without fans” has become so accepted as to be cliché among some commentators. But Chinese state TV has been testing that assumption to its limit throughout the World Cup.
On Monday, as Ghana beat South Korea in a classic World Cup clash, subtle changes to China’s coverage of the match ensured viewers were not exposed to images of maskless supporters – and to a world moving on from Covid restrictions.
Autocratic regimes who act like China and Russia are doing now, have always come to a sticky and violent end.
When will these idiots ever learn?
Beware Of Getting Hospital Appointments Wrong
On Monday, I had an appointment for an ultrasound examination on my liver at the local hospital at 09:40.
The appointment had been arranged by telephone and I also had a text which included the phrase “Please refer to your letter for pre-attendance advice and instructions.” I had been given basic instructions over the telephone, but I did not receive the letter. This is not the hospital’s fault, as I have received many letters in the past from the hospital and its Trust.
But my post has been very erratic these last few weeks and I suspect the letter is delayed somewhere.
As it happened, it didn’t matter, as the basic instructions sufficed and the ultrasound was a success all round.
Perhaps, in these days of problems with the Royal Mail, it may be prudent to include minimum instructions in the text message reminder.
University Of Manchester And National Grid Team Up To Develop SF6-Free Retrofill Solution For Electricity Network
The title of this post, is the same as that of this press release from National Grid.
This is the introductory paragraph.
National Grid and the University of Manchester are to collaborate on a four-year project to develop a full-scale demonstrator at the Deeside Centre for Innovation, designed to test at scale how the UK can retrofill sulphur hexafluoride (SF6) across its network of high-voltage equipment.
Note.
- Sulphur hexafluoride (SF6) is a gas commonly used in the power industry to provide electrical insulation and arc interruption.
- Eighty percent of sulphur hexafluoride is used in the electricity industry.
- According to Wikipedia, sulphur hexafluoride has several important applications, including a medical one in eye surgery.
- But sulphur hexafluoride is a is a potent greenhouse gas with a global warming potential that is 25,200 times greater than CO2.
It certainly looks to be a good idea to see if the sulphur hexafluoride can be eliminated from electrical equipment and other uses, that may release the gas into the atmosphere.
These paragraphs from the press release outline the project.
The £1.9m project will see experts at Manchester help determine how National Grid can develop a retrofill solution to replace SF6 with an environmentally friendlier alternative without having to replace or otherwise modify the existing equipment.
This solution – to be demonstrated at National Grid’s test facility the Deeside Centre for Innovation – will mean National Grid can avoid the environmental impact and cost of replacing equipment otherwise fit for many more years’ service.
It is not the first time National Grid and the University of Manchester have teamed up on a project exploring SF6 alternatives – a previous initiative which concluded in 2020 is now up for an IET Engineering & Technology magazine innovation award for ‘Best Innovation in Net Zero and Sustainability’.
The press release also says this about the Deeside Centre for Innovation.
National Grid’s Deeside Centre for Innovation in North Wales is the first of its kind in Europe, where electricity network assets can be tested under real life conditions, 24 hours a day, seven days a week.
It certainly seems that National Grid and Manchester University are on top of the problem and have the resources to achieve success in the project.
The Russian Attack On Ukraine
You may wonder what this has got to do with improving transformers and switchgear in Manchester and Wales.
Recently, the Russians have been targeting the Ukrainian electricity network. Are Ukrainian transformers and switchgear insulated with sulphur hexafluoride and if they are how of this potent global warming gas has been released into the atmosphere?
Rescued By A B12 Injection
Last week, I wasn’t feeling too well, as I wrote in The Hour Change Has Completely Knocked Me Out.
I had a whole raft of symptoms.
- Not being able to get dressed.
- Sleeping all the time.
- Poor hand-eye co-ordination.
- Dizziness, which got me to hospital.
Then on Tuesday, this week, I had my three-monthly B12 injection.
And all the symptoms disappeared.
The Hour Change Has Completely Knocked Me Out
Last Saturday, the 29th of October, the clocks went back and I’ve not had a totally good week.
On Tuesday, I couldn’t get dressed, as my gammy left arm and hand didn’t work.
- I also felt a bit unsteady, as if I’d had a couple of whiskies. But then, I never drink anything more alcoholic, than 0.0% real ale.
- As there was no-one else, I dialled 999.
- An ambulance came and took me to the Royal London Hospital, where nothing was found.
- But as my body responded to the hospital’s superb air-conditioning, I was allowed to go home.
- T think the hospital thought I took a taxi, but in reality I took the Overground to Dalston Junction station.
They had suggested, that I should take my planned trip to Doncaster. Which I did!
- I took a Hitachi Class 800 train to the North.
- And I took an InterCity225 train home.
Both have air-conditioning that only affects me positively, unlike Class 390 trains, which have put me in hospital before.
On Thursday, I wrote up my trip, or at least the ticketing in An Affordable Trip To Doncaster.
On Friday, I fell asleep on the floor and missed a friend bringing round my washing.
On Saturday, I woke late, went out for lunch and then watched the television.
In the evening, I was tired so went to bed at nine, which is unusual for me.
I got up at nine and did my trip on the Elizabeth Line, which I wrote about in Taking A Train Between Abbey Wood And Ilford Stations On The Lizzie Line.
As a Control Engineer, I tend to believe that the loss of the hour a week ago, has been the cause of my erratic sleeping.
- I should also note, that as a child, I dreaded the clock changes.
- I was also a strong supporter of the Daylight Saving Bill and wrote a post called An Open Letter to my MP About Changing to Central European Time.
I’ve also got a strange skin that I wrote about in My Strange Skin.
