Subject:
Duke Energy Corporation McGuire Nuclear Station, Units 1 and 2 Docket Numbers 50-369 and 50-370 Technical Specifications Amendment Request for Additional Information (RAI)
Implementation of 10 CFR 50, Appendix J, Option B for Type B and C Testing
Reference:
Letter from Mr. H.B. Barron to NRC dated December 7, 2001 (MB3565 and MB3566)
This letter provides additional information that was requested by the NRC staff on June 24, 2002. Attached you will find the excel spreadsheets which contain the ten year historical data for the McGuire penetration leakage rate testing of the containment purge valves associated with the recent License Amendment Request (LAR) . The only significant leakage in the last four and a half years has been during the outage after stroking the valves. In these cases the leakage tests are not really surveillance tests, but are functional verifications that the valves are sealed before relying on them for containment isolation during the next fuel cycle.
A new T-ring design implemented for all containment purge valves over several outages has resolved the chronic leakage problems. After implementing the modifications, acceptable valve leakage has been maintained during the following successive cycle until valves are again stroked
U.S. Nuclear Regulatory Commission July 22. 2002 Page 2 in the next outage. The most recent non-outage leakage test failure (Unit 1, 1/29/98) was caused by gasket sealant dripping down onto the valve disc seating surfaces causing non-uniform deformation of the T-ring to seat seal. After diagnosing and resolving the issue, this problem has not recurred.
Leakage testing results of these containment purge valves for the last three cycles has demonstrated acceptable performance. These valves are maintained closed during modes 1 to 4 with power removed and no benefits are realized from on-line leakage testing. Therefore, it is only necessary to perform leakage testing of the containment purge valves during the refueling outages as requested in the LAR.
If you have any questions with respect to this matter, please call Norman T. Simms of Regulatory Compliance at 704-875-4685.
Sincerely yours, H.B. Barron Attachments
