Nuclear Energy, Power Plant, and Reactor Sourcebook: NRC Modeling Potential Reactor Accident Consequences, Report on Security Inspection Program, A Day in the Life of an NRC Resident Inspector

This is a print replica reproduction of several important documents from the Nuclear Regulatory Commission (NRC): 2012 NRC Report: Modeling Potential Reactor Accident Consequences, the 2014 Report to Congress on the Security Inspection Program, and A Day in the Life of an NRC Resident Inspector. Two bonus documents are also included: Citizen’s Guide to U.S. Nuclear Regulatory Commission Information and 2016 Congressional Budget Justification.

The State-of-the-Art Reactor Consequence Analyses (SOARCA) research project to estimate the potential health effects from the unlikely event of a commercial nuclear power plant accident releasing significant quantities of radioactive material into the environment. This project modeled a set of important accident scenarios for two plants, Peach Bottom and Surry, which represent two of the most common types of plants licensed in the United States. SOARCA considers plant design and operational changes not reflected in earlier assessments. The project also takes into account NRC’s development of rigorous oversight processes and use of operating experience along with improvements in operator training and emergency preparedness. We’ve also incorporated decades of national and international research into the tools that NRC used to perform this study.

Results were as follows: When operators are successful in using available onsite equipment during the accidents analyzed in SOARCA, they can prevent the reactor from melting, or delay or reduce releases of radioactive material to the environment. SOARCA analyses indicate that all modeled accident scenarios, even if operators are unsuccessful in stopping the accident, progress more slowly and release much smaller amounts of radioactive material than calculated in earlier studies. As a result, public health consequences from severe nuclear power plant accidents modeled in SOARCA are smaller than previously calculated. The delayed releases calculated provide more time for emergency response actions such as evacuating or sheltering for affected populations. For the scenarios analyzed, SOARCA shows that emergency response programs, if implemented as planned and practiced, reduce the risk of public health consequences. Both mitigated (operator actions are successful) and unmitigated (operator actions are unsuccessful) cases of all modeled severe accident scenarios in SOARCA cause essentially no risk of death during or shortly after the accident. SOARCA’s calculated longer term cancer fatality risks for the accident scenarios analyzed are millions of times lower than the general U.S. cancer fatality risk.
