Attachment I W3FI-2005-0080 NRC Bulletin 2003-01 RAI
Attachment I to W3F1-2005-0080 Page 1 of 1 NRC Request for Additional Information COA 5, "Refill of Refueling Water Storage Tank," you concluded that "this is currently covered under the SAMGs" without further explanation. Since the intent of the COA, as stated in WCAP-16204, Appendix A, is to include guidance in the EPGs/ERGs to ensure that "stating the prerequisites and line up for the refill will occur as soon as circumstances allow," and further, that for CE plants this guidance would be contained in the "LOCA Optimal recovery Guidelines(ORG) after step 21, LPSI Restart Criteria and in a similar location in the Functional Recovery Guideline," it is not understood how this guidance can be appropriately placed in the SAMGs. (FYI: for Westinghouse plants, the intent is stated another way - to be conducted when critical operator actions are completed but not until after transfer to recirculation).
Response
As documented in Waterford 3's letter W3F1 -2005-0058 dated 10/20/05, the refill of the RWSP is covered under the Severe Accident Management Guidelines (SAMGs).
Waterford 3 will put in procedures OP-902-002, Loss of Coolant Accident Recovery and OP-902-008, Functional Recovery Procedure, the requirement to line up and refill the RWSP as soon as critical operator actions are completed after a LOCA, but not until after switchover to recirculation.
