Risk-Informed License Amendment Reviews

PNNL supported NRC in development of its flagship risk-informed fire protection program.

Activities in which PNNL has been engaged include

  • Re-drafting of Regulatory Guide 1.205, "Risk-informed, Performance-Based Fire Protection for Existing Light-water Nuclear Power Plants" as well as Standard Review Plan (NUREG-0800) Section, "Risk-Informed, Performance-Based Fire Protection Program"
  • Development of the safety evaluation report template for risk-informed fire protection as defined in NFPA 805
  • Review of license amendment requests (LARs) for NFPA805-based programs
  • Review of LARs associated with NRC Initiative 4(b) and 5(b) for risk-informed technical specifications
