REQUEST FOR ADDITIONAL INFORMATION RELATED TO RELIEF REQUESTS DATED NOVEMBER 22, 2002 NUCLEAR MANAGEMENT COMPANY, LLC MONTICELLO NUCLEAR GENERATING PLANT DOCKET NO. 50-263 On Page 2 of 6 of Attachment 5, of your November 22, 2002, Valve Relief Request No. VR-01, you requested alternative testing based on paragraph ISTC 4.5.4(c). This would allow valve testing to be performed in groups instead of each and every valve. You said that "All 121 check valves are identical in all essential respects and will be considered a single group for a similar sampling approach for exercise to the close position." ISTC 4.5.4(c) requires in part, the following:
(1) Grouping of check vales shall consider valve manufacturer, size, material of construction, orientation, and maintenance and modification history.
(2) At least one valve from each group shall be disassembled and examined at each refueling outage; all valves in each group shall be disassembled and examined at least once every 8 years.
(3) The details and bases of the sampling program shall be documented and recorded in the test plan (see ISTC 6.2).
It is unclear how your single grouping of 121 check valves address these requirements.
Therefore, please provide 1) justification for the single grouping in view of the ISTC 4.5.4(c) requirements, or 2) provide the appropriate grouping of all the 121 check valves instead of one group of 121 valves with one valve testing every refueling outage.
