Proposed Approach for Staff Review of Plant Specific Modelling of Generation-III Shutdown Seals in License Amendment Requests (LARS)
Generation III Shutdown Seals (GIII-SDS) Modeled in PRA(s)
Used to Support LAR Was the GIII-SDS model in the PRA peer-reviewed? Case 1(Consistent with review of pee r-reviewed PRA)
Verify and review that the licensee:
1.Provided finding level F&Os and their resolution AND 2.Described how the staff SE on GIII-SDS is met, all the limitations and conditions (L&Cs) therein are satisfied, and justified any deviations. Did GIII-SDS modeling use a peer-reviewed WOG-2000 model as foundation? Case 3Verify and review that the licensee:
1.Demonstrated (on a plant-specific OR generic basis) why inclusion of GIII-SDS is not a PRA upgrade.
2.Described how the staff SE on GIII-SDS is met, all the L&Cs therein are satisfied, and justified any deviations. Case 4 Perform a detailed review of GIII-SDS modeling, alignment with staff SE, and L&Cs details via audit and RAIs OR Licensee either convenes peer-review or removes credit (follow approach for Case 1 or 2, as appropriate). Licensee chooses to not credit the GIII-SDS in the LAR? Case 2Verify and review that the licensee:
1.Demonstrated on the docket (via sensitivity) that the removal of credit for GIII-SDS does not affect the decision and insights. 2.Clarifies when, and if, the credit will be used.
