- Abstract
- The Nuclear Regulatory Commission (NRC) has instituted an initiative for regulatory improvement to focus licensee and NRC resources on risk-significant activities, and to decrease the prescriptiveness of its regulations through performance-based methods that allow licensees increased flexibility in implementing NRC regulations. The NRC has identified risk-informed methods utilizing insights from probabilistic risk analysis (PRA) as a major tool for achieving its goal for regulatory focus. The issue of fire protection requirements has been identified as a regulatory area in which NRC will pursue regulatory improvement. This report presents a technical review and analysis of risk-informed, performance-based methods that are alternatives to those in current prescriptive fire protection requirements or guidance that could allow cost-effective methods for implementing safety objectives, focusing licensee efforts, and achieving greter efficiency in the use of resources for plant safety. A technical analysis of the usefulness of the results andinsights dervied from these methods (including accounting for the uncertainties in the results) in improving regulatory decision making is represented.
