Fast Breeder Reactors

Pro-nukers should be celebrating, Russia is claiming success developing fast breeder reactors.

No nuclear waste: Fuel of future produced at Russia's high-tech underground plant

Nuclear bonds: Russia supplies fuel for China Experimental Fast Reactor

Quote:“The cooperation in the field of fast reactor technologies, including the fuel cycle, bears a strategic importance as it aims at the creation of dual-component nuclear power system in the future.”

Will the MOX fuel increase nuclear proliferation risks? Liquid metal sodium coolant was the failure point in earlier attempts to use fast breeder reactors. The coolant is highly corrosive and flammable. While it sounds like a good way to use up spent nuclear fuels, I wonder when we'll have another nuclear accident as they test the technology with increased production.

Canada 2018

Just weeks after its success in being selected as a winner in the UK government’s Advanced Modular Reactors competition, Moltex is delighted to announce that it has also been selected by New Brunswick Energy Solutions Corporation and New Brunswick Power to progress development of its SSR-W (Stable Salt Reactor - Wasteburner) technology in New Brunswick, with the aim of deploying its first SSR-W at the Point Lepreau nuclear reactor site before 2030.

The agreement provides $5m of financial support to Moltex for its immediate development activities and Moltex will open its North America headquarters in Saint John and build its development team there.

“The Moltex stable salt reactor technology is a perfect fit for New Brunswick’s power needs,” said Moltex CEO Stephen Haighton. “It uses spent nuclear fuel, which could help solve the province’s future spent-fuel disposal challenge. It is a physically small modular reactor but is able to store energy, so can double or triple its output at peak demand times during the day. Most importantly, the stable salt reactor technology produces very low-cost, clean energy and can reduce the cost of electricity to consumers while achieving low-carbon targets. We are very excited to join our new partners and establish our North American headquarters in New Brunswick.”

TOKYO -- The French government has informed Japan it will halt joint development of advanced nuclear reactors, Nikkei has learned, dealing a blow to the fuel cycle policy underpinning much of the East Asian country's energy plans.

France is expected to halt research from next year into the Advanced Sodium Technological Reactor for Industrial Demonstration project, or Astrid, and stop setting budgets for the fast breeder reactors from 2020.

French President Emmanuel Macron revealed plans Tuesday to cut France's nuclear reliance to 50% from the current 70%. Under that plan, the Astrid project, which has faced ballooning construction costs and cutbacks, appears to have been viewed as less urgently needed.

The French government denied it has made an official decision on the matter, according to Reuters. But the consideration comes at a time when tensions between Tokyo and Paris are mounting over the arrest of former Nissan Chairman Carlos Ghosn, and Renault's control over the Japanese automaker.

Japan viewed Astrid as a keystone of its plans to recycle spent nuclear fuel. The country pulled the plug in 2016 on its own prototype fast breeder reactor. That reactor, known as Monju, encountered a great deal of trouble and incurred heavy costs over its decades-long history.

TOKYO/PARIS (Reuters) - France’s state-run nuclear agency said on Thursday it had presented options on a new generation of fast-breeder nuclear reactors to the French government and talks were underway but dismissed reports in Japan that it had taken a decision.

The Nikkei business daily reported that France had informed Japan it would halt research into the ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) project in 2019, with no plans to allocate a budget from 2020.

A spokesman for the CEA nuclear agency said one option it had discussed was to reduce ASTRID’s capacity to a 100-200 megawatt (MW) research model from the commercial-sized 600 MW originally planned.

Japan’s Chief Cabinet Secretary Yoshihide Suga said on Thursday he had not been informed about any French plans to freeze the project and that nothing has been decided.
...
...In theory, breeders could turn utility EDF’s nuclear waste into fuel and make France self-sufficient in energy for decades. Their potential is part of the reason why France recycles spent fuel from EDF’s reactors, separating out plutonium in state-owned Orano’s reprocessing plant in La Hague.

Could be a lot more interesting then Fukushima explosion I suppose.. /SARC

sry, it's a lot of work and battery draining to make such a simple post on a phone but to show I'm trying lol

" The coolant is highly corrosive and flammable. While it sounds like a good way to use up spent nuclear fuels, I wonder when we'll have another nuclear accident as they test the technology with increased production"

I can't copy and paste from the last link but I wanted to highlight the failure

All good DUDe, the youtube video of the Fuku explosion shows the start of another nuclear disaster we were told would never happen.  Again and again radioactive contamination spreads around the globe.  Always declared safe and always covered up, people don't know what nuclear technology has already cost us.  The expense is obscene and health consequences are patently ignored so as not to affect the bottom line.  Lives don't matter when there's money to be made.  Here's a choice quote from your wiki link.  

Quote:An accident in December 1995, in which a sodium leak caused a major fire, forced a shutdown. A subsequent scandal involving a cover-up of the scope of the accident delayed its restart until May 6, 2010, with renewed criticality reached on May 8, 2010.[4] In August 2010 another accident, involving dropped machinery, shut down the reactor again. As of June 2011, the reactor has only generated electricity for one hour since its first testing two decades prior.[5] As of the end of 2010, total funds spent on the reactor amounted to ¥1.08 trillion. An estimated ¥160–170 billion would be needed to continue to operate the reactor for another 10 years.[6]

As of 2014, the plant had cost ¥1 trillion ($9.8 billion).[7]

The hopes for this technology run high because it closes the fuel cycle and could be used to recycle spent fuel.  Many previous designs of fast breeder reactors have failed.  The nuclear industry proudly proclaims, this time will be different, new and improved, economical and safe.  Yeah, right.

Excactly Horse, i remember "we never thought this could happen" in hindsight..after every living being has been "oeps-ed"

Thanks for the quote!
