SUBJECT:
NRC BULLETIN NO. 88-11, " PRESSURIZER SURGE LINE THERMAL STRATIFICATION" - EVALUATION OF WESTINGHOUSE OWNERS GROUP BOUNDING ANALYSIS (TAC NO. 72136 AND 72145)
By letter dated June 2, 1989, Northeast utilities responded to Item 1.b of NRC Bulletin No. 88-11. " Pressurizer Surge Line Tnermal Stratification" (PSL).
The letter stated that a bounding analysis performed by the Westinghouse Owners Group (WOG).is applicable for Haddam Neck and Millstone Unit 3.
The analysis stated that the integrity of the PSL was adequate to justify continued operation of the facility for s weral years.
The staff has completed its review of the WOG bounding analysis and concludes that there are no short-term safety concerns associated with the thermal stratification effects for a duration of 10 fuel cycles of continued plant operation.
A copy of the evaluation which was sent to the WOG is enclosed for your information.
The staff will assess the conformance of the PSL to applicable Codes and regulatory requirements for 40 year plant life when the WOG report regarding Item 1.d of the Bulletin is submitted.
Sincerely,
/s/
