Radiation probes indicate NO melt through at Fukushima Unit 1

Tepco has recently released measurements that provide convincing evidence that virtually all of the corium in Fukushima Daiichi unit #1 remains safely stored inside an intact reactor pressure vessel. Despite all claims to the contrary, no substantial quantities of that material have melted through the pressure vessel to fall onto the concrete floor of the…

Conservative groupthink afflicts US nuclear energy industry

Though I have a deep and abiding respect for the vast majority of the people I have met who work in the nuclear energy industry, it is time for me to risk losing a few friends with some brutal honesty. Decision making has become unbalanced in the “conservative” direction to a point of a dangerous…

The Atomic Show #184 – Kirk Sorensen, Co-Founder Flibe Energy

Kirk Sorensen is the co-founder and chief technologist of Flibe Energy. He is a member of a tiny club of people who can honestly claim to be atomic entrepreneurs. He is a brilliant man – one of the few people who has been both a rocket scientist and a nuclear engineer. Kirk is best known…

Identifying antinuclear slants in Richard Martin’s “Superfuel”

Richard Martin’s new book titled Superfuel: Thorium, The Green Energy Source for the Future is a book that should come with a warning label. Though the author professes to be worried about climate change and fossil fuel depletion and wants to be seen as favoring new nuclear power development, that support comes with a very…

San Onofre (SONGS) owner updates public on cause of steam generator tube wear

The US Nuclear Regulatory Commission’s Augmented Inspection Team (AIT) held a public information meeting on June 18, 2012 to present findings from their investigation into the cause of the excessive steam generator tube degradation found in units 2 and 3 of the San Onofre Nuclear Generating Station (SONGS). Southern California Edison (SCE), SONGS owner and…

Pronuclear videos continuing to proliferate – The Nuclear Option

With a hat tip to Ben Heard at Decarbonize SA, I thought it might inspire you to see two videos side by side. These videos were created in geographic locations that are about as far apart as you can get and still be on Earth. As far as I can tell, neither creative team knew…

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…

Ontario’s CANDUs can be more flexible than natural gas and hydro

By: Donald Jones, P.Eng. There is a widely held belief that commercial nuclear-electric plants are only capable of baseload operation when in fact they can be more flexible than a natural gas-fired generating station. This belief has led the Ontario government to restrict nuclear generation to 50 percent of total demand, in its Long-Term Energy…

Pebble bed reactor safety demonstration test – ABC video from 2007

I spent about 15 years trying (unsuccessfully) to get a small modular reactor company off the ground. Our concept was based on an adaptation of the successful German pebble bed demonstration reactor called the AVR. In 2003, Tsinghua University in China completed the construction of the HTR-10, which was essentially a direct copy of the…

What do you do with the waste? – Kirk Sorensen’s answers

Gordon McDowell, the film maker who produced Thorium Remix, has released some additional mixes of material gathered for that production effort. One in particular is aimed at those people whose main concern about using nuclear energy is the often repeated question “What do you do with the waste.” Many people who ask that question think…
