3.9.6 Inservice Testing of Pumps and Valves j

l The applicant for Seabrook Station submitted an inservice testing (IST) l program by letter dated December 31, 1985.

This submittal was reviewed by i

the staff and was the subject of a working meeting with the applicant on May 13 and 14,1986. Based on staff comments during the working meeting the applicant submitted Revision 1 to their IST program by letter dated June 4, 1986. Revision 1 was amended by letter from J. DeVincentis to V. S. Noonan dated June 18, 1986 and letters from G. S. Thomas to V.S.

Noonan dated June 23, 1986 and June 25, 1986. Revision I dated June 4, 1986 as amended by letters dated June 18, 23 and 25,1986 constitute the Seabrook IST program that has been reviewed by the staff.

The applicant's IST program is required by 10 CFR 50.55a(g) to comply with the ASME Boiler and Pressure Vessel Code,Section XI,1983 Edition through Summer 1983 Addenda. Pursuant to 10 CFR 50.55a (g)(5) the applicant for

}

Seabrook has requested relief from the ASME Code Testing requirements for specific pumps and valves where the Code requirements are impractical within the limits of design, geometry, and accessibility.

Each of the applicant's request for relief included an explanation and justification for the relief and a proposal for alternative t'est procedures.

The staff, with technical assistance from the Idaho National Laboratory (INEL), has reviewed the applicant's IST program and relief requests. A technical Evaluation Report (TER) prepared by INEL is included as an Appendix to this SER Supplement.

Based on this review the staff concludes that the applicant's IST program meets the requirements of 10 CFR 50.55a(g) and is therefore acceptable.

In addition, for each relief request the applicant's alternative IST procedure, basis for requesting relief, the staff evaluction of the request and staff conclusion are fully discussed in the Aprendix to this SER supplement. Based on review of the i

1 7

applicants request for relief, the staff concludes that the requirements of 10 CFR 50.55a(6)(1) are met and are therefore acceptable. Granting the relief requested by the applicant will not endanger life or property or the j

comon defense and is'otherwise in the public interest giving due 4

consideration to the burden on the applicant if the request were not granted.
