New generation of nuclear reactors consume radioactive waste as fuel

A generation of "fast" nuclear reactors could consume Britain's radioactive waste stockpile as fuel, providing enough low-carbon electricity to power the country for more than 500 years, according to figures confirmed by the chief scientific adviser to the Department of Energy and Climate Change (Decc).

Britain's large stockpile of nuclear waste includes more than 100 tonnes of plutonium and 35,000 tonnes of depleted uranium. The plutonium in particular presents a security risk as a potential target for terrorists and will cost billions to dispose of safely. The government is currently considering options for disposing of or managing it.

Burning energy questions – ERoEI, desert solar, oil replacements, realistic renewables and tropical islands

Posted on 19 January 2012 by Barry Brook

Late last year, Tom Blees, I and a few other people from the International Award Committee of the Global Energy Prize answered reader’s energy questions on The Guardian’s Facebook page. The questions and answers were reproduced on BNC here. Now we’re at it again, this time for the website Eco-Business.com (tagline: Asia Pacific’s sustainable business community). My section is hosted here (Part I), and Tom’s here (part III).

Part II, which I don’t reprint, answered by Iceland’s Thorsteinn Sigfusson, covered the relationship between large-hydro and climate change, and why solar conversion isn’t used more extensively.

Two scientist revolutionaries get their due

The dilemma of providing abundant energy to humanity while avoiding the seemingly inescapable environmental, social, economic and political pitfalls associated with energy production and distribution is arguably one of the most vexing problems of modern times. In order to encourage advancements in energy research and recognise potentially revolutionary energy advancements, a group of Russian scientists, politicians and leaders of industry established the Global Energy Prize in 2002. Widely seen as an energy research equivalent of a Nobel Prize, it has been awarded to deserving researchers annually since 2003.

Disposal of UK plutonium stocks with a climate change focus

Response to a consultation on the management of the UK’s plutonium stocks

June, 2011

In the 1950s, following World War II, the United Kingdom and a handful of other nations developed a nuclear weapons arsenal. This required the production of plutonium metal (or highly enriched uranium) purpose-built facilities. ‘Civil’ plutonium was also produced, since the facilities for separation existed and it was thought that this fissile material would prove useful in further nuclear power development. Fifty years on, the question of what to do with the UK’s separated plutonium stocks is an important one.

Tom Blees, President, of The Science Council for Global Initiatives, explores answers to the question, " "Do you agree that it is not realistic for the Government to wait until fast breeder reactor technology is commercially available before taking a decision on how to manage plutonium stocks?" I strongly disagree, and I hope that you’ll take the time to read this and consider the fact that the fast reactor option is far more imminent than you might have heretofore believed. Not only that, but it is arguably the best option by far.

Current Fast Reactor Development

Worldwide there are well over 300 reactor-years of experience with fast reactors. Russia’s BN-600 fast reactor has been producing commercial electricity for over 30 years, and Russia is beginning to build BN-800 reactors both for their own use and for China. India’s first commercial-scale fast reactor is about to be finished within a year or two. South Korea has already built a sizeable pyroprocessing facility to convert their spent LWR fuel into metal fuel for fast reactors, and have only refrained from starting it up because of diplomatic agreements with the USA that are due to be renegotiated in the near future. China is building a copy of the Experimental Breeder Reactor II (EBR-II) that was the mainstay of the Integral Fast Reactor (IFR) development program at Argonne National Laboratory in the USA. Japan has reopened their Monju fast reactor to continue that research, though it should be noted that Toshiba and Hitachi contested the wisdom of that decision, favoring instead the metal-fueled fast reactor design as exemplified by the EBR-II.

The advantages of metal fuel in fast reactors is difficult to overstate. Rather than attempt to explicate the details here, I would refer the reader to the following URL: http://tinyurl.com/cwvn8n This is a chapter from a book that deals at length with the Integral Fast Reactor (IFR). The advantages of this system in safety, economics, fuel utilization, proliferation resistance and plutonium breeding or burning far outstrip any of the other options mentioned in the consultation document.
