UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 Docket Nos. 50-272/311 Mr. Steven E. Miltenberger Vice President and Chief Nuclear Officer Public Service Electric & Gas Company Post Office Box 236 Hancocks Bridge, New Jersey 08038
Dear Mr. Miltenberger:
May 16, 1989
SUBJECT:
SCHEDULAR RELIEF REQUEST RELATED TO NRC BULLETIN 88-11, "PRESSURIZER SURGE LINE THERMAL STRATIFICATION", ITEM 1.b (TAC NOS. 72161/72162)
RE:
SALEM GENERATING STATION, UNIT NOS. 1 AND 2 The purpose of this letter is clarify the information provided to you in our letter dated May 2, 1989, on the implementation schedule for Item 1.b of NRC Bulletin 88-11, "Pressurizer Surge Line Thermal Stratification" that was mutually agreed upon between the NRC staff and the Westinghouse Owners Group (WOG) during an April 11, 1989 meeting. This information supersedes the information in the May 2, 1989 letter.
By letter dated March 6,_1989, Public Service Electric and Gas Co. proposed an alternate schedule for the completion of the bounding analysis required by Item 1.b of NRC Bulletin 88-11 regarding the design adequacy of the pressurizer surge line, taking into account the effects of thermal stratification. Your proposed schedule for completion of item l.b (two years from receipt of the Bulletin) was consistent with the alternate schedule proposed by the WOG program.
During the April 11, 1989 meeting between the staff and the WOG, the staff stated that the alternate schedule as originally proposed by the WOG was unacceptable. Based on additional discussion, the WOG agreed to notify its membership that licensees of plants in operation over 10 years should, by the end of May 1989, complete and have available for NRC audit, their bounding analysis as related to Item l.b of the Bulletin, and submit to the NRC, a Justification for Continued Operation (JCO) in the event the results of the bounding analysis do not confirm the adequacy of the plant pressurizer surge line for the design life of the plant. Licensees of plants in operation less than 10 years would be notified that they were required to complete the required actions of Item 1.b within the originally stated period (one year from receipt of the Bulletin). The staff found these proposals to be acceptable.

It is our understanding that the WOG will provide you with a "generic" bounding analysis, to which your plant specific variables (e.g., seismic and thermal loadings) will need to be added and incorporated. Your analysis should assess all aspects of thermal stratification and thermal striping, including bounding evaluations on stresses and fatigue, based on currently available information.
Based upon your participation in the WOG program regarding this issue and absent any other justification, your proposed alternate schedule of completing Item l.b is not approved.
It is our expectation that your efforts will be accelerated to meet the completion dates as connnitted to by the WOG.
