While in a cold shutdown condition, during the conduct of a review of plant systems to satisfy the requirement of NRC Bulletin 79-02, it was determined that the Reactor Building Cooling System Supply and Return Lines to the Drywell Equip-ment Drain Sump did not have a seismic stress analysis performed. At this time it has not been determined, with certainty, if a seismic stress analysis is re-quired for the 1 1/2" Cooling Water Supply and Return Lines associated with the sump cooler.

If the investigation indicates that a seismic analysis should have been performed this event will be an example of failure to implement administrative or procedural instructions that are required by Technical Specification Appendix A, Paragraph 6.9.A.4.2.c.

When the investigation has been completed a follow-up to this interim report will be submitted.
