Risk-Informed Decision Making: Application in Nuclear Power Plant Design & Operation

摘要

Generally, a risk-informed analysis will involve a relatively broad spectrum of disciplines and realistic engineering analysis as required in NRC guidance. Traditionally, engineering analysis in commercial nuclear power applications has lacked detailed uncertainty analysis and quantification. Instead, "worst case" or credible extremes are evaluated separately. Where uncertainty has been evaluated , it is not clearly related to risk or scenario importance. Quantification of risk and uncertainty is a basic need in a risk-informed regulatory paradigm.
