How Did the MOX Project Get So Expensive?

Over the past week or so, I’ve engaged in a “root cause analysis” project to determine why the US is having so much difficulty implementing a plan to take 34 metric tons of nearly pure plutonium 239 — a fissile isotope with virtually the same energy value as uranium 235 — out of our nuclear…

Sad-ending story of EBR-II told by three of its pioneers

During the period between 1961 and 1994, an extraordinary machine called the Experimental Breeder Reactor 2 (EBR-II) was created and operated in the high desert of Idaho by a team of dedicated, determined, and distinguished people. In 1986, that machine demonstrated that it could protect itself in the event of a complete loss of flow…

Integrating six decades of learning about fast reactors

I learned some important new concepts yesterday from two of the leaders of the Integral Fast Reactor (IFR) project – John Sackett and Yoon Chang. Among other things, they informed me — as a member of a group of about 35 other attendees at a workshop titled Sustainable Nuclear Energy for the Future: Improving Safety,…

How do metal alloy fuel fast reactors respond to rapid reactivity insertion events?

Update: (Posted Feb 21, 2015 at 7:22) The title has been modified after initial discussion indicated it was incomplete. Other related updates are in blue font. Fast neutron spectrum reactors offer one answer to the trump question that is often used to halt informative discussions about using more atomic energy to reduce our excessive dependence…

Slowly accelerate fast reactor development

In one corner are people who are certain that breeder reactors that can effectively use the earth’s massive supply of fertile isotopes — thorium and uranium 238 — should be pursued as rapidly as possible with the assistance of prioritized government funding. In the other corner are people who are just as certain that those…

Russia continues sustained fast breeder reactor effort

On June 26, 2014, the 60th anniversary of the start of the 5 MWe Obninsk reactor that was the first reactor in the world to routinely supply electricity to a commercial power grid, Russia started up the latest in a series of sodium-cooled fast reactors, the BN-800. This new nuclear plant is an evolutionary refinement…

Reuters Breakout series focuses on China’s interest in thorium

Reuters is running a series titled Breakout: Inside China’s Military Buildout. Installment number 6 is titled The U.S. government lab behind Beijing’s nuclear power push. The title is misleading; it is not about China’s world-leading, multibillion-dollar program. That program includes 29 large commercial nuclear plants currently under construction. Instead, the article focuses on a $350…

Fantasy Crossfire debate: Ed Lyman versus Rod Adams on fast breeder reactors

CNN has done a masterful job of seizing the opportunity provided by Robert Stone’s thought-provoking Pandora’s Promise to generate a passionate discussion about the use of nuclear energy — a vitally important topic — at a critical time in American history. The decision makers at that somewhat fading network should be congratulated. Of course, generating…

Hydrocarbon-fueled establishment hates idea of plutonium economy

In the above clip from a recent interview on CNN’s Piers Morgan, Robert F. Kennedy, Jr. describes how Pandora’s Promise advocates that canceling the Integral Fast Reactor (IFR) project in 1994 was a mistake. RFK Jr., a man from an iconic family that has been a part of the US moneyed Establishment for the better…

Pursuing the unlimited energy dream – history of the Integral Fast Reactor

Note: Len Koch, whose participation in nuclear energy research started in the 1940s, wrote the below open letter to colleagues who are striving to restore interest in the progress that they made in research and development of the Integral Fast Reactor during the period from 1954-1994 the year that President Clinton and Hazel O’Leary, his…
