Overview of the HNP and FNP Emergency Plan Staffing Studies 13Emergency Plan Staffing Studies
- HNP and FNP Staffing Studies were updated based upon the SER approved Standard Emergency Plan.
- Performed in accordance with NEI 10
-05 to document the adequacy of shift staffing as required by 10 CFR 50 Appendix E.
- NRC staff guidance directs the scenarios that must be used to demonstrate the adequacy of on
-shift staffing to perform required functions for event mitigation, radiation protection response, firefighting, chemistry and Emergency Plan functions. Those scenarios include specific design basis accidents as described in the FSAR as well as specific scenarios defined in the Staff Guidance document.
- NEI 10-05 Appendix A events were either analyzed for HNP and FNP or reason provided that the events were not included in the study
- 9 of 14 events were analyzed for FNP
- 8 of 12 events were analyzed for HNP 14Emergency Plan Staffing Study Conclusion
- The minimum staff for FNP and HNP is adequate to respond to the scenarios identified in the regulations until relieved by the augmented ERO.
- The analysis showed that the number of on
-shift personnel are sufficient to respond to analyzed events until augmented by the ERO 75 minutes after event declaration and that no conflicts in responsibilities exist.
- NEI 12-01 staffing study (FLEX/BDB) was also updated concurrent with the NEI 10-05 update.
