Lessons learned from severe accidents in nuclear reactors.
The International Atomic Energy Agency (IAEA) defines severe accidents as “Accident conditions more severe than a design basis accident and involving significant core degradation”. Fukushima-Daiichi, Chernobyl, and Three Mile Island are well known examples, but there have actually been at least 19 such accidents. The speaker has researched and summarized these events for the IAEA and in a report for the Electric Power Research Institute. This talk will give a short overview of these severe accidents and lessons learned..
Gary Johnson is an Independent Consultant (i.e., a retired guy who refuses to quit). His career included stents with the International Atomic Energy Agency, Lawrence Livermore National Laboratory, Portland General Electric Company, and the US Department of Energy, not to mention a short time as a visiting scholar in Berkeley’s Nuclear Engineering Department. Most of his work focused on the safety of nuclear power plants and plant instrumentation and control. He is still actively supporting IAEA training for newcomer countries, and the development of technical studies and standards for the IAEA, the Institute of Electrical and Electronic Engineers Nuclear Power Engineering Society, the International Electrotechnical Commission Subcommittee on Nuclear Facility Instrument, Control, and Electrical systems, the World Nuclear Association, and ANS.
