This is an August 2022 update of an article first published in November 1996 and updated in February 2019. The first update was stimulated by discussions associated with DOD’s issuance of an RFI for mobile, modest power output atomic power systems. That RFI resulted in Project Pele, which has now selected BWXT to build a…
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…
Seventy one years ago — on December 2, 1942, at 3:25 pm — Enrico Fermi and his team achieved the first controlled, man-made, self sustaining chain reaction in a simple reactor. In recognition of that historical event, several of my nuclear colleagues refer to December 2 as “Critmass” (short for critical mass). The first nuclear…
Almost exactly 50 years ago today, President John F. Kennedy, Jr. visited Hanford, Washington to give a speech about the importance of electrical power and the role that he expected nuclear technology would play in the future. (HT to the TriCity Herald for posting the video provided by the Department of Energy and to Martin…
Mitsubishi Heavy Industries (MHI), the supplier that sold four new steam generators to Southern California Edison (SCE) for the San Onofre Nuclear Generating Station (SONGS), has issued a redacted version of its root cause analysis of the u-tube failures that have kept both of the station’s 1100 MWe units shut down since January 31, 2012….
Ted Rockwell has been an active participant in the development of nuclear energy production in the United States since the very earliest days of the technology. He started his nuclear career as an engineering troubleshooter in 1943 at the site that is now Oak Ridge National Laboratory during the Manhattan Project. He was one of…
I’m doing a little history reading today and came across a passage worth sharing. The source is Glenn Seaborg’s “The Atomic Energy Commission Under Nixon” St. Martin’s Press, NY 1993 pg 101-102. In December 1965, the management of Northern States Power Company (NSP) reached an internal decisions that a new generating unit in the 500-electrical-megawatt…
On Sunday, December 2, 2012, I gathered together a group of nuclear professionals to talk about the impact to human history of the construction and operation of Critical Pile 1 (CP-1). That simple assembly of graphite, uranium, and uranium dioxide was built in about 6 weeks. When measurements taken during construction indicated that the system…
In the summer of 2012, Argonne National Laboratory recorded the first hand memories of two members of the group of 49 engineers, scientists and students who were present when mankind first proved that it could control a fission chain reaction. Just imagine – you can watch a very recently recorded account from people who were…
Reed College is perhaps best known among technologists as the place where Steve Jobs learned about calligraphy – among a number of other useful topics. It is also the only liberal arts college that owns a research reactor that is operated primarily by undergraduates. I hope you enjoyed Will and Norm’s visit to the Reed…
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…
Kirk Sorensen is the founder of Flibe Energy. He has been prospecting in libraries for years to learn more about a path not taken (yet). He is convinced that the way forward for energy in the United States and around the world is the molten salt thorium reactor that can produce an almost unlimited amount…
