| Expansion and Use of Risk-Informed Process for Evaluations |
|---|
| The Risk-Informed Process of Evaluations (RIPE) can be used to defer or eliminate compliance issues with a minimal safety impact using existing regulations. The Nuclear Regulatory Commission (NRC) approved this initiative that utilizes licensee’s previously approved risk-informed initiatives to inform licensing actions in January 2021. The initiative leverages current regulations and uses risk information to identify low safety significant issues that US licensees can use to submit plant-specific regulatory actions for issues that would support a streamlined review by the NRC using existing programs and processes that are consistent with Regulatory Guide 1.174, “An Approach for Using Probabilistic Risk Assessment In Risk-Informed Decisions On Plant-specific Changes to the Licensing Basis” (Agencywide Documents Access and Management System (ADAMS) Accession No. ML100910006). The NRC expanded the use of RIPE to include other risk-informed initiatives and to allow for Technical Specification changes. In addition, the first application using the RIPE process was submitted involving the diverse feedwater actuation requirement in the 10 Code of Federal Regulations 50.62 “Requirements for reduction of risk from anticipated transients without scram (ATWS) events for light-water-cooled nuclear power plants.” This paper will discuss the expansion of RIPE and the first use of the initiative and lessons-learned from that submittal. |
