Joseph M. Farley Nuclear Plant Response to NRC Request for Additional Information on License Amendment Request for Technical Specification Table 3.3.1-1 in Response to Westinghouse NSAL 09-01, "Rod Withdrawal at Power" RAI1 The staff is requesting information about the bounding allocation time for the PFRT function for Farley, Units 1 and 2. Note that the WCAP-13632-P-A, Revision 2, "Elimination of Pressure Sensor Response Time Testing Requirements," allows users to estimate response time allocation times, using the specific channel card string for the protective function. Please indicate whether that is SNC's practice in this regard. If a different practice or approach is used to derive the allocation time, please include a specific explanation in your response.
SNC Response The allocation times (from WCAP 14036-P-A, Rev. 1 "Elimination of Periodic Channel Response Time Tests"), Table 8-1, are as follows:
NIS PR HIGH FLUX - LO SUM AMP + BISTABLE: 65ms Input + Logic + UV: 20ms NIS PR HIGH FLUX - HI SUM AMP + BISTABLE: 65ms Input + Logic + UV: 20ms These values were previously provided via email to the NRC staff reviewer.
