Evaluation of Severe Accident Risks: Quantification of Major Input Parameters.Experts' Determination of Containment Loads and Molten Core Containment Interaction Issues

摘要

The Severe Accident Risk Reduction Program (SARRP) has completed a revisedcalculation of the risk to the general public from severe accidents at five nuclear power plants: Surry, Sequoyah, Zion, Peach Bottom and Grand Gulf. The emphasis in this risk analysis was to determine the distribution of risk, and to discover the uncertainties that account for the breadth of the distribution. Off-site risk initiated by events, both internal to the power station and external to the power station was assessed.
