Pioneering nuclear fusion power plants are to be fast tracked through the planning process and supported with taxpayer money as Britain attempts to become a world leader in the technology.

Under new proposals by the Government, commercial fusion reactors will be exempt from the usual planning rules governing nuclear power stations.

One of the major changes will be to class nuclear fusion reactors as nationally significant infrastructure projects, with ministers deciding if they should go ahead and preventing local authorities from scrutinising them.

It means companies planning fusion reactors can avoid the years of red tape blocking current nuclear power stations.

Why not do that with fission plants?

The UK has a stockpile of plutonium and uranium big enough to power every household in the country for six years, or up to a century if it continues to be re-processed, according to the Adam Smith Institute (ASI).

The think tank is urging the Government to draw on these reserves as a source of clean energy, while liberalising the “sclerotic” planning system to accelerate Britain’s nuclear development.

Some countries, including France and Japan, already recycle their nuclear waste to make fuel. Britain also used to be a world leader in re-processing, but only used the technique recommended by the ASI on a relatively small scale.

Of course, entirely true.

The think tank said fuel can be made from nuclear waste by mixing plutonium and uranium compounds, turning the blend into small pellets and heating these in a sintering furnace at 1,700C for 36 hours. The pellets are then inserted into a fuel tube, welded shut and put into a reactor. With 140 tonnes of plutonium at the Sellafield nuclear site in Cumbria, of which 100 can be used for this purpose, and thousands of tonnes of uranium in the UK, the ASI estimates that Britain has the resources to create enough fuel to power every household for six years.

MOX, great stuff, the only reason not to use it is interminable reguilation. Something that government can solve – if it wishes to.

Five workers were cleaning pipes at the system filtering wastewater for release into the sea when two were splashed after a hose came off accidentally, according to a spokesperson for operator Tepco.

Two others were contaminated when they were cleaning up the spill, the spokesperson added.

The radiation levels in the two hospitalised men were at or above 4 becquerels per square centimetre, the threshold which is considered safe.

“We’ve been told the condition of the two workers being hospitalised is stable,” the Tepco spokesperson said.

Actually, perhaps we should start using “the Conrwall” as our measure of radioactivity. If someone who knows their maths – as all know, I do not – would care to produce a little table for us? This water at Fukushima in Cornwalls, natural uranium in Cornwalls, a thermonuclear bomb in Cornwalls…..

The Fukushima Daiichi plant, on Japan’s north-eastern coast, was hit by a massive tsunami caused by a 9.0-magnitude earthquake, the strongest in Japan’s recorded history.

More than 18,000 people died in the tsunami, but no one was recorded as having been directly killed by the nuclear meltdowns,

Even George Monbiot is on board with this. Absolutely, entirely, the worst happened and no one was killed at all.

Makes Mutti look more than a little silly using it as an excuse to turn off the German reactors really……

The controversial release of more than a million tonnes of water from the wrecked Fukushima Daiichi nuclear plant will begin in the northern spring or summer, Japan’s government has said – a move that has sparked anger among local fishing communities and countries in the region.

The decision comes more than two years after the government approved the release of the water, which will be treated to remove most radioactive materials but will still contain tritium, a naturally occurring radioactive form of hydrogen that is technically difficult to separate from water.

We’ll not in fact be able to tell. If we test the Pacific Ocean now, then test it again after the release, we’ll simply not be able to show that the release happened.

All the screaming about this is total pish. Political pish at that.

So, the Met would tell me exactly what uranium they’d found at Heathrow. And yes, I did talk to them. So I can’t in fact give an opinion on what was being smuggled, or it was a mistake, or what. Because I don’t know what the scrap was, nor what type of uranium it was.

We can make one assumption, it was scrap moving by air. So, the scrap was worth more than $5 or so a kg. Not steel therefore, not unless it was a high stainless. Other than that, dunno.

If it was zirconium tubing contaminated – ie, a smearing or some powder – with U then that’s evidence of someone playing naughty games with U concentration etc. But not dangerous at this end. If it’s a chunk of depleted U then who knows? Bit off a helicopter rotor? Some tank scrap from a firing range?

Shrug?

If it were xyz scrap with a chunk of U sitting in the middle, well, maybe someone smuggling the U.

He told The Telegraph: “If you were to use depleted uranium in a ‘dirty bomb’, like any isotope it would cause a contamination issue – but there are a lot more radioactive isotopes out there that would be easier to get hold of and would have a much greater effect.

“It’s definitely a possibility that this could have been some form of reconnaissance or dry run to test how the security was operating during the industrial action.”

Mr Ingram said that while the discovery of the uranium was concerning, there was some comfort to be found in the fact that even a small amount had been successfully identified during routine checks at Heathrow.

Well, yes, except depleted U wouldn’t normally be detected in the usual sort of radioactive sensors. Someone runs a Feuss over it then it’s obvious, obviously.

It is understood the uranium was contained within metal bars, and experts have said it is “pretty much unheard of” to ship scrap metal around the world by air freight because of the cost.

Depends which metal. But as at the top, fair point except for some real funnies.

Oh, and as to dirty bombs, he’s quite right. You’d not, by preference use U anyway. One of the medially used isotopes would be far preferable. The stuff made by a U fusion explosion that is, not the U itself – or something close at least.

Will anything be banned from entry? “Bananas!” Barberio exclaims. Rich in potassium, they are slightly radioactive.

Saskatchewan and Ontario have each chosen GE-Hitachi as the supplier of small modular nuclear reactors (SMRs), which could be deployed in the Prairie province by the 2030s and in Ontario by 2018.

Ontario has a time machine now.

Boris Johnson’s plans for a nuclear energy revolution are facing a fresh hurdle after the Austrian government officially raised concerns about the safety of a new reactor design.

In a letter to the Business Department, Austria’s energy ministry raised the spectre of “severe accidents with high releases” at the Sizewell C plant to be built in Suffolk.

The warning, made under the Espoo convention in which nearby countries are allowed to comment on nuclear projects, raises the prospect of legal action to derail Sizewell and will be considered by the Government as part of a planning decision in coming months.

We spent 5 years rolling through the design. 5 sodding years. At which point the Austrian Greens – and they’re terrible, really – stick their oar in again. Sigh. Just build the damn things.

Recall that old Sellafield thing? So:

If Northvolt is going to succeed in its plans to build Europe’s biggest battery factory, it and its host city need to convince thousands of people to move to the edge of the Arctic Circle, to a region where snow cover is constant from November to April and where the winter sun shines for no more than four hours a day.

Leukaemia is, oddly, something that can be caught. Large mixtures of people from many different places seems to cause outbreaks. Thus the Sellafield cluster – all those workers from all over.

I predict the same here. Without, of course the insistence that it’s all because nucular. Indeed, I predict it’ll never be mentioned.

said Edwin Lyman, director of nuclear power safety with the Union of Concerned Scientists science advocacy nonprofit….(…)…“Honestly I don’t understand the motivation,” Lyman said. “There are some people who are just strong advocates for it and they’ve sort of won the day here by convincing Bill Gates that this is a good technology to pursue.”

Re liquid sodium nuclear plants.

As a motivation, how about the idea that civilisation rather likes the idea of reliable power supplies?

A nuclear power plant in China owned by the companies developing new power stations in the UK has been shut down for “maintenance” after cracks were found in fuel rods.

China General Nuclear (CGN) said the reactor at the Taishan plant, about 80 miles west of Hong Kong, was safe and under control, and the damage was within the “allowable range”.

The problem is more likely at the plant that made the rods than with the reactor……or with the design or operation of the reactor that is.

Not that I’d recommend eating these piggies but:

A genetic study found that wild boar cross-bred with domestic pigs escaped from local farms in areas deserted by humans after a tsunami and an earthquake triggered the 2011 crisis at Fukushima nuclear power plant and displaced 160,000 people.

For years, hunters have been tracking down radioactive boar, which number in their hundreds and registered levels of the radioactive element caesium-137 300 times higher than is safe.

If the boar are breeding and carrying on happily at 300x “safe” then our definition of safe is pretty restrictive……

Imagine a nuclear battery in a little box that uses decaying isotopes to generate cheap and clean electricity around the clock for decades with no combustion, fission, or noise. It just sits silently and emits constant power.

This far-fetched idea is becoming real. Vaulting advances in materials sciences are unlocking technologies that radically change the cost calculus of radioisotopes. Companies are springing to life with prototypes that could be on the market before the next general election.

As it happens, the UK is the world leader in the rarified field of isotope batteries. A British-Australian start-up with research operations in Cumbria has found a way to harness gamma rays from the radioactive decay of cobalt-60. Infinite Power thinks it can cut costs to levels that take your breath away. “It is the cheapest source of electricity on the planet,” says Robert McLeod, the chief executive.

I can’t actually imagine anyone allowing dispersed C-60 floating around the countryside.

We have had the occasional incident where a piece – from a cancer treatment machine – ends up in a scrap yard and kills people. It’s a gamma ray emitter which is why we use it as the radiation source to burn up cancers, also what makes the battery work. Whether it’s actually a good idea or not it’s just not gonna happen – public opinion just isn’t going to allow it in car battery chargers which is one of the suggested uses.

Depending on how countries classify waste, only about 0.2–3% by volume is high-level waste, according to the World Nuclear Association (WNA), a London-based industry group that promotes nuclear power.

Mostly derived from civil reactor fuel, this is some of the most dangerous material known on Earth, remaining radioactive for tens of thousands of years. It requires cooling and shielding indefinitely and contains 95% of the radioactivity related to nuclear power generation.

Well, no, not really.

But the idea was boosted in December 2018 by French Nobel prize–winning physicist Gérard Mourou, who, in his acceptance lecture, said laser beams millions of times brighter than the surface of the sun in bursts that last a millionth of a billionth of a second had the potential to neutralise nuclear waste, reducing its half-life to a few years and its radioactivity to very little.

Largely speaking and not wholly and exactly the higher the radiation danger now the shorter the period of time for which it is dangerous. And vice versa. The not wholly is because plutonium is nastily poisonous without radioactivity etc. Thorium poses heavy metal poisoning dangers rather greater than its radioactivity etc.

Hitler was just a ferry-ride away from getting hold of a crucial ingredient needed for an atomic weapon to blow up London, a new documentary has discovered.

In the middle of a Norwegian lake, 100 miles from Oslo, naval historians and scientists have located the boat on which the Nazis were transporting barrels of heavy water for use in German nuclear reactors.

The Hydro ferry was sunk on Churchill’s orders in 1944, but until now nobody knew if the craft really was containing vital component that Hitler needed for his nuclear arsenal.

The reason the Nazis didn’t get the bomb is that they didn’t take getting the bomb seriously.

Getting it in the sort of timescale the Americans did would have required devoting the same sort of resources to it that the Americans did. Getting it by 1960 was trivial but not of a great deal of use when Berlin fell in 1945. Getting it by 1944 when it might – might note – have made a difference required rather more effort. Which they simply didn’t devote to it.

Sure, we can look at certain aspects, this heavy water for example. Or the raid on the Norwegian plant itself. But no, they weren’t going to get there, not the way they were doing it.

Nuclear waste could be stored under some of the most beautiful parts of the country prompting a row with rural campaigners.

A committee of MPs has controversially given the green light to Government plans which could see nuclear waste buried deep in vaults beneath England’s national parks.

The decision was condemned by campaigners who it put “our treasured landscapes under the threat of inappropriate and major development”.

No bugger’s allowed to do anything else with that land, is he? And it’s all being saved in perpetuity as well. What’s the hassle?

The dream of nuclear fusion is on the brink of being realised, according to a major new US initiative that says it will put fusion power on the grid within 15 years.

Well, maybe, and they do make the old joke. But this is nonsense:

The reaction also does not create greenhouse gases or produce hazardous radioactive waste of the sort made by conventional nuclear fission reactors.

You really wouldn’t want to stand around the chunks of steel which make up the reactor after it’s been on for long.

Russia reports radioactivity 986 times the norm after nuclear accident claim

Rather, they report levels of one specific radioactive isotope near 1,000 times normal.

Background radiation up to 1 k normal levels would be a crisis. 1 k normal levels of this type of Ruthenium are an interesting little puzzle we’d like to find the answer to but not a danger to anything in any manner.

An increase of 1,000 times in the amount of music being played would be a large change. An increase of 1,000 times in one specific single being played on the radio is something different, no?

For two decades, Alberto Rodriguez has worked in the same cavernous garage along the border between Queens and Brooklyn, surrounded by the clang of metal and the rumbling of engines awaiting repair.

It turns out that he has also been toiling amid potentially dangerous levels of radiation.

Mr. Rodriguez’s shop, Los Primos Auto Repair and Sale, is one of six businesses at the intersection of Cooper and Irving Avenues in Ridgewood, Queens, that have been targeted for demolition as part of a cleanup plan released recently by the Environmental Protection Agency. The businesses are within a Superfund site, the term for sites covered by a program that finances the cleanup of hazardous waste.

Ooooh, gosh!

Mr. Rodriguez’s shop sits atop land formerly occupied by the Wolff-Alport Chemical Company, which from the 1920s through the 1950s extracted metals from imported sand. In the process, the company produced waste containing two radioactive elements, thorium and uranium, which it disposed of by dumping the waste into sewers and perhaps also by burying it, according to the federal plan.

Well, OK, that’s not good practice, certainly. BTW, yes, they were producng rare earths, from monazite, which does indeed contain thorium and uranium. So, how dangerous is it?

If no further remediation were done at the site, a future resident would see an increased risk of cancer of about 0.005 percent, the plan predicted.

So, umm, nothing. And how much will it cost?

The projected cost of the government’s preferred plan for the Wolff-Alport cleanup is more than $39 million.

It’ll cost bundles. So, we’re to spend a lot to achieve nothing. It’s environmentalism gone mad I tell ‘ee!

I would wager that that risk is lower than moving across the Tamar into Cornwall…..and remember, the EU insists that Cornish pasties much actually be made in such a radioactive area these days.
