SUBJECT:

SAFETY EVALUATION FOR COMBUSTION ENGINEERING OWNERS GROUP REPORT CEN-387-P, REVISION 1, " PRESSURIZER SURGE LINE THERMAL STRATIFICATION EVALUATION" (BULLETIN 88-11) (TAC NOS. M72169 AND M72170)

By letters dated March 6, April 4, and July 31, 1989, you responded to NRC Bulletin 88-11 a'nd indicated that you were participating in the Combustion Engineering Owners Group (CE0G) effort to evaluate pressurizer surge line thermal stratification. The staff and its consultant, Brookhaven National Laboratory, have completed their review of the CEOG Report CEN-387-P,

" Pressurizer Surge Line Flow Stratification." The staff concludes that the CEOG analysis adequately demonstrates that the bounding surge line and nozzles meet ASME Code stress and fatigue requirements for the 40-year design life of the facility considering the phenomena of thermal stratification and thermal striping.

The staff's safety evaluation of CEN-387-P, Revision 1, is enclosed.

Action 1.d of Bulletin 88-11 required licensees to update their stress and fatigue analyses to ensure compliance with applicable Code requirements. The CEOG Report can be used to update plant-specific Code stress reports as required by Action 1.d.

Please verify the applicability of the CEOG bounding analysis in CEN-387-P, Revision 1 to St. Lucie Units 1 and 2.

In addition, please confirm that all actions required by Bulletin 88-11, including the updating of the plant-specific stress and fatigue analyses required by Action 1.d, have been completed. Your response is requested within 60 days of receipt of this letter.

j This request is covered by Office of Management and Budget Clearanco Number 3150-0011, which expires June 30, 1994. The estimated averaae number of sygam 4#
