mportant contributors to risk. SATISFY SRs of HLR HR-H, except where the requirements are not applicable. WPR-D8 through WPR-D10 ------------------------ No objection --------------------------------- WPR-D11 Failing to perform a feasibility assessment may result in some HEPs being assigned a value less than 1.0 when the assigned value should be 1.0. If an HFE that is not feasible is assigned an HEP value less than 1.0, but a feasibility assessment would otherwise demonstrate that the HFE is not feasible, the PRA model may underestimate the risk from that contributor. Qualification CC-I …When addressing feasibility, influencing factors, and the timing considerations in Requirements HR-G1, HR- G4, HR-G6, and HR-G8, INCLUDE the effect of high wind hazard on the control room and ex-control room human actions. CC-II …When addressing feasibility, influencing factors, and the timing considerations in Requirements HR-G1, HR- G4, HR-G6, and HR-G8… Table 4.3.12.3-6 WPR-E1 through WPR-E7 ------------------------ No objection ---------------------------------- Table 4.3.12.3-7 WPR-F1 through WPR-F3 ------------------------ No objection ---------------------------------- Section 4.3.12.4 Section 4.3.12.4.1 Section text ------------------------ No objection ---------------------------------- RG 1.247, Appendix A, Page A-58 Table A-13.
