SUBJECT:

LICENSEE CONFIRMATION OF ITS RESPONSE TO NRC BULLETIN 88-08:

THERMAL STRESSES IN PIPING CONNECTED TO REACTOR COOLANT SYSTEMS (TAC 69636)

By letters dated September 20,1987andJune 30, 1989, Connecticut Yankee Atomic Power Company (licensee) on behalf of Haddam Neck, responded to NRC Bulletin 88-08: Thermal Stresses in Piping Connected to Reactor Coolant Systems. In their responses, the licensee confirmed that analyses to address the issues discussed in the Bulletin have been performed and the_ actions necessary to resolve this Bulletin will be perf rmed during the current refueling outage.

In addition, depending on the results of the actions taken 3

during the outage an Intergrated Safety Assessment Program evaluation will be conducted to determine the need and schedule for any necessary work to eliminate valve leakage, modify the piping to withstand thermal stresses, or-prevent the upstream piping from exceeding'RCS pressure.

By copy of this memorandum, Region I is advised of the licensee's position on this matter. The date of this memorandum is considered the closecut date for the TAC number.
