This is a print replica reproduction of an important document from the Nuclear Regulatory Commission (NRC): 2014 NRC Consequence Study of a Beyond-Design-Basis Earthquake Affecting the Spent Fuel Pool for a U.S. Mark I Boiling Water Reactor. Bonus documents are also included: Citizen's Guide to U.S. Nuclear Regulatory Commission Information, 2016 Congressional Budget Justification, Status Report on U.S. Nuclear Energy Program.U.S. nuclear power plants are required to be designed with appropriate consideration of the most severe natural phenomena (e.g. floods, earthquakes, tornadoes) historically reported for their location and surrounding regions, with sufficient margin, to ensure that important safety functions can be performed. As part of our mission to protect public health and safety, the U.S. Nuclear Regulatory Commission (NRC) uses advanced computer modeling and other techniques to study more severe, and highly unlikely, events that go beyond what the plant was designed to withstand to estimate risk to the public and to explore and ensure safety margins. On March 11, 2011, the Tohoku earthquake and subsequent tsunami in Japan resulted in significant damage to the site of the Fukushima Dai-ichi nuclear power station. Although the spent fuel pools and the used fuel assemblies stored in the pools remained intact at the plant, the event led to questions about the safe storage of spent fuel and whether the NRC should require the expedited transfer of spent fuel from pools to dry cask storage containers at U.S. nuclear power plants. This report documents the Office of Nuclear Regulatory Research’s consequence study that continues our examination of the risks and consequences of postulated spent fuel pool accidents. A spent fuel pool’s robust concrete structure and stainless steel liner keep more than 20 feet of water above the spent fuel stored within it ensuring ample cooling for the spent fuel and adequate radiation shielding for plant personnel. About every two years, some used fuel is removed from the reactor and placed into the spent fuel pool. The used fuel most recently removed from a reactor is radiologically and thermally “hot”. The hot fuel is distributed throughout the pool and is surrounded by older, cooler used fuel. After used fuel has cooled in the spent fuel pool for more than about five years, it has radiologically decayed such that it can be moved to dry storage casks for longer term storage. This study compared potential accident consequences from a pool nearly filled with spent fuel and a pool in which fuel that has cooled sufficiently has been removed. The staff first evaluated whether a severe, though unlikely, earthquake would damage the spent fuel pool to the point of leaking. In order to assess the consequences that might result from a spent fuel pool leak, the study assumed seismic forces greater than the maximum earthquake reasonably expected to occur at the reference plant location. The NRC expects that the ground motion used in this study is more challenging for the spent fuel pool structure than that experienced at the Fukushima Daiichi nuclear power plant from the earthquake that occurred off the coast of Japan on March 11, 2011. That earthquake did not result in any spent fuel pool leaks. In the small likelihood that such an extreme earthquake caused a leak, the staff then analyzed where the leak would be expected, the size of the leak, and how the spent fuel could overheat and potentially release radioactive material into the environment. Finally, the staff analyzed what the public health and environmental effects of a radiological release would be in the area surrounding the plant. In order to estimate the hypothetical consequences, the staff analyzed scenarios where some preplanned and improvised mitigative actions by the emergency response organization were either not successful or not implemented.Nuclear Energy, Power Plant, And Reactor Sourcebook: 2014 Nrc Consequence Study Of A Beyond-design-basis Earthquake Affecting The Spent Fuel Pool For A ...
