NIA submitted a public comment on Nuclear Regulatory Commission Draft Regulatory Guide DG-1443 Comprehensive Risk Metrics and Associated Risk Performance Objectives for Commercial Nuclear Plants.
NIA supports the reasonable approach outlined in the DG-1443 Comprehensive Risk Metrics and Associated Risk Performance Objectives for Commercial Nuclear Plants and encourages NRC to continue to work with stakeholders as the guidance is implemented. The outlined approach is aligned with NIA’s previous work. In particular, in our Comprehensive Risk Metrics for Nuclear Reactor Regulation report, NIA had recommended a flexible, predictable, self-consistent, and
implementable process for applicants to put forward, and for NRC to approve, these risk metrics. Under DG-1443, NRC describes three different approaches that applicants could use. DG-1443 is also responsive to NIA's call for NRC to provide guidance regarding the implementation of the new comprehensive risk metrics.
