FOIJLOWUP RESPONSE TO NRC BULLETIN 88 PRESSURIZER SURGE LINE THERMAL

'STRATIFICATION By letter dated March 2, 1989 Consumers Power Company submitted an initial response to NRC Bulletin 88-11, Pressurizer Surge Line Thermal Stratification.

In this response we informed the NRG that Consumers Power Company was a participant ih the CE Owners Group (CEOG) program to address pressurizer surge line thermal stratification concerns. The CEOG has completed a generic bounding analysis report, CEN-387-P, which has been submitted for NRC review by _the owners group. Palisades is covered by this report. The referenced report concludes the structural integrity of the pressurizer surge line is acceptable for the forty year life of the plant.

Consumers Power Company was required to* confirm that the Palisades pressurizer surge line* hanger travel is within the bounds assumed in CEN-387-P. Pressurizer surge line hanger travel was confirmed by engineering walkdown on November 1, 1989.

As required by the Bulletin, this submittal is to inform the NRC all of the Actions Requested which are applicable to Palisades have been completed. The results of our actions completed are available for NRC inspection.
