Insights from a Risk-Informed Standardized Technical Specifications Pilot Project at San Onofre Nuclear Generating Station

摘要

San Onofre Nuclear Generating Station is a pilot plant in the implementation of a Risk-Informed Standardized Technical Specifications project. The objective of this project is to incorporate risk insights into several major elements of the Technical Specifications. As a pilot plant for this effort. San Onofre has performed a number of risk evaluations using its full power, shutdown and transition modes Probabilistic Safety Assessment model. Sensitivity studies have also been performed to demonstrate the applicability of the risk insights to other Pressurized Water Reactors. The results to date indicate that plant flexibility can be provided and public safety improved through the adoption of these changes.
