Fire Probabilistic Risk Assessment (PRA) and Probabilistic Safety Assessment (PSA): NFPA standards and Regulatory Guide 1.189

A1204

For utilities that have decided to retain their 10CFR50, Appendix R licensing basis, NRC Regulatory Guide 1.189 has provided a path to use specific performance-based tools to evaluate and mitigate risks within the plant. Based on the NRC guidance, Fire Probabilistic Risk Assessment (Fire PRA) methodology can be used to mitigate circuit issues, such as Multiple Spurious Operations (MSOs).
