SUBJECT:

RELIEF FOR HYDROSTATIC TESTING AFTER NUCLEAR SERVICE WATER SYSTEM MODIFICATIONS - MCGUIRE NUCLEAR STATION, UNITS 1 AND 2 RELIEF REQUESTS 88-05 AND 89-02 (TAC 68972, 68973, 72215 and 72216)

By letters dated June 27, 1988, and February 16, 1989, you requested relief from the hydrostatic pressure testing requirement of Section XI of the ASME Boiler and Pressure Vessel Code,1980 Edition through Winter 1980 Addenda, IWA-4400 and IWB-5000. The requests (Nos. 88-05 ano 89-02, respectively) are associated with modifications to the Nuclear Service Water System for McGuire Nuclear Station, Units 1 and 2. Specifically, the modifications are those identified by your following nuclear station modification (NSM) numbers:

hSM MG-12233, Revision 0 NSM MG-52128, Revision 0 NSM MG-22233, Revision 0 NSM MG-12107, Revision 0 NSM MG-12243. Revision 0 NSM MG-22107 Revision 0 NSM MG-2224 2evision 0 NSM MG-12129, Revision 0 NSM MG-22130, Revision 0 NSM MG-22129, Revision 0 In lieu of the required hydrostatic test, you proposed non-destructive exam-ination consisting of dye penetrant or magnetic particle examination of the welds and inservice leak tests.

The staff agrees that the specific requirements of Section XI of the ASME Boiler and Pressure Yessel Code,1980 Edition through Winter 1980 Addenda, are impractical in these cases, so that relief from the inservice hydrostatic tests required by Section XI is justified. Your alternative non-destructive examination and inservice leak testing will provide an acceptable level of structural integrity. Our Satety Evaluation is enclosed, m
