--------------------------------- HR-H2 Having a limited set of feasibility criteria and constraining their applicability only to recovery actions (i.e., a special case of post- initiator actions) may result in an incomplete feasibility assessment and Qualification Add the following two feasibility criteria: (f) there is a sufficient plan for command and control; and (g) there is a sufficient plan for communications. RG 1.247, Appendix A, Page A-19 Table A-7. Staff Position on ASME/ANS RA-S-1.4-2021, Technical Requirements for Human Reliability Analysis Index No. Issue Position Resolution assigning an HEP of less than 1.0 when the assigned value should be 1.0 (see the “Issue” column for HR-G1). Ensuring that there is sufficient command and control, and communications is important because NLWRs lack the operating experience and the NLWR PRA standard scope includes all radiological sources, all hazards, all POSs, and all levels of analysis.
