SUBJECT:
NRC BULLETIN NO. 88-11, "PRESSURIZER SURGE LINE THERMAL STRATIFICATION 11 EVALUATION OF WESTINGHOUSE OWNERS GROUP BOUNDING ANALYSIS, SALEM GENERATING STATION, UNITS 1 AND 2 (TAC NOS.
72161 AND 72162)
By letter dated May 31, 1989, Public Service Electric and Gas Co. responded to Item l.b of NRC Bulletin No. 88-11, 11Pressurizer Surge Line Thermal Stratification.
11 The letter stated that a bounding analysis performed by the Westinghouse Owners Group (WOG) for Salem 1 and 2 is applicable and indicated that the pressurizer surge line (PSL) may not satisfy the ASME Section III Code criteria for the life of the plant, taking into account the effects of thermal stratification. The analysis did, however, state that the integrity of the PSL was adequate to justify continued operation of the facility for several 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 additional heatup/cooldown 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.
