(2) Feasible—an operator action that can be credited in RG 1.247, Appendix A, Page A-4 Table A-1. Staff Position on ASME/ANS RA-S-1.4-2021, NLWR Standard Introduction, Acronyms and Definitions, and Risk Assessment Application Process Index No. Issue Position Resolution is a continuous step in the human reliability analysis (HRA) process. Definitions related to feasibility are needed to eliminate ambiguous interpretation. a PRA model if the action has met all the feasibility assessment criteria (see supporting requirement HR-H2).
