REQUEST FOR ADDITIONAL INFORMATION REGARDING THE 4th INTERVAL INSERVICE INSPECTION PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNIT 1 AND 2 DOCKET NOS. 50-282 AND 50-306 Please provide your written response to the following Nuclear Regulatory Commission staff questions:
- 1. The NRC staff accepted Code Case OMN-9, with the condition that (1) when the repair, replacement, or routine servicing of a pump may have affected a reference curve, the licensee must determine a new reference curve, or reconfirm an existing reference curve, in accordance with Section 3 of Code Case OMN-9; and (2) if it is necessary or desirable, for some reason other than that stated in Section 4 of Code Case OMN-9, to establish an additional reference curve or set of curves, the licensee must determine the new curves in accordance with Section 3 of Code Case OMN-9. Please discuss how these conditions will be implemented when utilizing Code Case OMN-9 as requested in Relief Requests 6, 7, and 8? Please verify that the comprehensive pump test will be performed within plus or minus 20 percent of pump design flow as required by ISTB.
- 2. Relief Request #11 states the valves will be disassembled, manually stroke exercised and inspected once each fuel cycle. Will the valves be inspected each cycle on a refueling outage frequency (i.e., 18 months)? Please provide a qualitative or quantitative discussion of the risk associated with testing the check valves on line versus during an outage. Please provide an overview of the program controlling on line maintenance. Please provide a time estimate to perform the valve inspection and the technical specifications allowed outage time. If the inspection is to be performed in conjunction with other maintenance activities please provide a time estimate to perform the other maintenance activities and discuss whether the valve inspection will impact the work window duration.
