James Lovelock: Why are we so afraid of nuclear power?

[moon]

Because radical Leftists, like Moon for example, are not just anti-science, they are imbeciles incapable of even beginning to understand how nuclear power actually works.

Anti BAD SCIENCE, dumbass.

Climate Deniers are the same people who were pandemic deniers and peddle the lie that nuclear pollution is good for us.


Haw, haw..............................haw.

There's a huge difference between "climate deniers" and people who are skeptical of the single-source theories that CO2 is the problem. This is particularly true as there is good, even excellent, science on the effects of methane, water vapor, aircraft contrails, etc., that people like you ignore out of political expediency wanting your preferred solutions regardless of science.

Whirligigs and sunshine cannot power the industrial world. It's that simple. It's scientific illiterates like you that cannot grasp reality and science.

There are many components, true- and it's dumbasses who REFUSE to change their lifestyles and alter the direction of ' progress ' that are threatening the rest of us. They are the enemy- and must be treated as such.

Biden's new IRA law will extend the lives of our remaining nuclear power plants, and incentivize building new nuclear power plants. trump talked about doing something, but did nothing... And proposed doing real damage to nuclear power. Biden has actually done some good.

MSRs, like thorium, don't seem to be very common.

"Why don't we use molten salt reactors?
These problems remain relevant. Even today, no material can perform satisfactorily in the high-radiation, high-temperature, and corrosive environment inside a molten salt reactor.Jun 20, 2022

Thorizon raises funds for MSR development
23 August 2022

Thorizon of the Netherlands has raised EUR12.5 million (USD12.4 million) for the development of a thorium molten salt reactor (MSR). Thorizon is a spin-off from the Nuclear Research and Consultancy Group (NRG), the organisation that operates the High Flux Reactor in Petten.

Thorizon said the investors "are a strong team of private and public sector parties". The private investors are venture capital fund Positron Ventures (lead investor), impact investor Invest-NL, one private investor, and the company Huisman which not only invests but will also become an industrial supplier. The public sector investors are the two provincial funds PDENH (lead investor) and Impuls Zeeland.

The company said it has been working on a thorium molten salt reactor "for several years". Its design uses a mixture of existing long-lived waste and the abundant metal thorium, whereby "a large amount of the long-lived waste can be turned into short-lived waste and CO2-free energy".

The EUR12.5 million investment, it said, will fund essential tests and research to complete the design of a first prototype. Thorizon aims to construct a pilot reactor system before 2035.

For the development of this technology, Thorizon will collaborate closely with several parties, such as France's Orano and NRG, the Dutch producer of medical isotopes and operator of nuclear research infrastructure. Together with EPZ, operator of the Borssele nuclear power plant, Thorizon will investigate the possibility of building the first reactor on the plant site. A broader consortium of research institutions including TU Delft and DIFFER, component suppliers and industrial service providers are supporting this development.

"What started as a good idea several years ago has developed into a very promising reactor design, we are very happy with the confidence of our investors and partners," said Thorizon co-founder Lucas Pool.

MSRs use molten fluoride salts as primary coolant, at low pressure. They may operate with epithermal or fast neutron spectrums, and with a variety of fuels. Much of the interest today in reviving the MSR concept relates to using thorium (to breed fissile uranium-233), where an initial source of fissile material such as plutonium-239 needs to be provided. There are a number of different MSR design concepts, and a number of interesting challenges in the commercialisation of many, especially with thorium.

The salts concerned as primary coolant, mostly lithium-beryllium fluoride and lithium fluoride, remain liquid without pressurisation from about 500°C up to about 1400°C, in marked contrast to a pressurised water reactor which operates at about 315°C under 150 atmospheres pressure.

The main MSR concept is to have the fuel dissolved in the coolant as fuel salt, and ultimately to reprocess that online. Thorium, uranium, and plutonium all form suitable fluoride salts that readily dissolve in the LiF-BeF2 (FLiBe) mixture, and thorium and uranium can be easily separated from one another in fluoride form. Batch reprocessing is likely in the short term, and fuel life is quoted at 4-7 years, with high burn-up.

THE WORLD
NUCLEAR WASTE
REPORT 2019

With reactors across the world approaching the end of their lives, decommissioning and dismantling of nuclear power plants will become increasingly important. This process will produce even more radioactive waste. In absence of final disposal sites, most of the high-level waste and spent nuclear fuel must be stored for many decades, challenging the safety requirements for storage facilities and causing much higher costs than previously estimated.

Secret nuclear waste disposal sites revealed

The highly sensitive shortlist of 12 sites where the UK nuclear industry wanted to dispose of its dangerous radioactive waste has been unveiled after being kept a closely guarded state secret for more than 15 years.

https://www.newscientist.com/article...ites-revealed/

NUCLEAR WASTE I: FINAL DISPOSAL SITE - THE OCEANS

The US demonstrated very early on how to quickly and cost-effectively dispose of nuclear waste: In 1946, the US put radioactive waste in 200-liter barrels and dumped them into the Pacific Ocean near the Farallon Islands, about 50 kilometers off the coast of California. As a result, the ocean became a nuclear waste dump. Decades later, the US government admitted to the International Atomic Energy Agency (IAEA) that up until 1970, the country had disposed of 90,000 barrels at different locations in the Pacific and the North Atlantic.

The Dutch, eh. I'm glad they are researching it. I assume a commercial plant will cost Billions?

Here's an article I'd like to hear your opinion on. Yes, it's anti nuke.



"Anti-nuclear campaigner Peter Karamoskos goes further, dismissing a 'dishonest fantasy' perpetuated by the pro-nuclear lobby.

Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – 'so these are really U-233 reactors,' says Karamoskos.

This isotope is more hazardous than the U-235 used in conventional reactors, he adds, because it produces U-232 as a side effect (half life: 160,000 years), on top of familiar fission by-products such as technetium-99 (half life: up to 300,000 years) and iodine-129 (half life: 15.7 million years).Add in actinides such as protactinium-231 (half life: 33,000 years) and it soon becomes apparent that thorium's superficial cleanliness will still depend on digging some pretty deep holes to bury the highly radioactive waste."

Well first things first, the article is over 11 years old and it's the Guardian!

Thorium reactors like all others needs fissile material to get started. Thorium itself is a neutron poison and needs to be irradiated by neutrons, it is referred to as fertile rather than fissile like uranium or plutonium. The key advantage of thorium fuel is it allows breeding with slow neutrons, hence using far less fissile material than you'd need in a fast breeder reactor.

Thorium can in fact be used in many types of reactor, seven to be precise, not just MSRs. This article explains that in detail.
