T11 Evolution of External Hazard Risks for U.S. Plants
Sponsored by the Office of Nuclear Reactor Regulation
In the 10 years since the accident at the Fukushima Dai-ichi nuclear power plant in Japan, the NRC and the nuclear industry have dedicated significant effort to reassessing external hazards at U.S. plants, including using probabilistic risk assessment methods. These evaluations have led to safety improvements at a number of U.S. plants. The understanding of the risk posed to nuclear power plant operations from external hazards has also improved among internal and external stakeholders. The improved understanding is supported by increased capability to model such risks. Various regulatory activities have demonstrated that it is important to consider the risks from external hazards. The purpose of this session is to communicate perspectives on the evolution of external hazard risks as well as the latest research in this area.
