SUBJECT:

SCHEDULAR RELIEF REQUEST RELATED TO NRC BULLETIN 88-11

" PRESSURIZER SURGE LINE THERMAL STRATIFICATION", ITEM 1.b (TACNOS.72155AND72156)

The purpose of this letter is to inform you of 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 4 westinghouse Owners Group (WOG) during an April 11, 1989 meeting.

By letter dated March 3,1989, Wisconsin Electric Power Company 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, takir.g into account the effects of thermal stratification. Your proposed schedule for completion of Item 1.b (2 years from the date of the Bulletin) was consistent with the alternate schedule proposed by the Westing-house Owners Group (WOG) program.

During an April 11, 1989 meeting between the staff and the WOG, the staff expressed that the alternate schedule as originally proposed by the WOG was unacceptable.

Based upon 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 1.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 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 (1 year from receipt oftheBulletin). The staff found these proposals to be acceptable.

analysis, to which your plant-specific variables (you with a " generic" bounding It is our understanding that the WOG will provide 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.
