SUBJECT:
PALISADES PLANT - EVALUATION OF UNRESOLVED FIRE PROTECTION INSPECTION ISSUES RELATED TO THE ADEQUACY OF TURBINE BUILDING FIRE AREA BARRIERS (TAC NO. M94148)
Dear Mr. Bordine:
On November 3, 1995, Consumers Energy Company submitted a method and a schedule for addressing unresolved fire protection issues that were identified in NRC inspection report (IR) 255/95004 dated May 19, 1995. The unresolved issues were related to (1) the adequacy of the west wall of the turbine lube oil storage room to provide 3-hour fire resistive protection for safety-related equipment located in the turbine building, and (2) the adequacy of the common turbine building/component cooling water (CCW) pump room wall with respect to protecting the CCW pumps in the event of a turbine building fire.
Consumers Energy provided an analysis and response for these unresolved fire protection issues to the NRC on February 2, 1996. The staff conducted an onsite review on February 12 and 13, 1996. During the onsite review, Consumers Energy stated that it would enhance the west wall of the turbine lube oil storage room and would provide additional sprinkler protection in the turbine building in the area of the turbine building/CCW pump room wall. By letters dated April 1, and December 9, 1996, Consumers Energy revised its submittal to incorporate the fire protection enhancements it had proposed during the staff's onsite review.
Our evaluation of the IR 255/95004 unresolved fire protection issues is enclosed. On the basis of our review, we have concluded that (1) the west wall of the turbine lube oil room, as modified by Consumers Energy, provides reasonable assurance that a fire in the lube oil room will not adversely impact safety-related/post-fire safe shutdown equipment located in the turbine building, and (2) the fire protection features provided in the vicinity of the
\\"\\ fo \\
common turbine building/CCW pump room wall, with the additional automatic sprinkler
~!J protection and other factors described in the enclosed safety evaluation (SE), provide
\\
reasonable assurance that a fire in the turbine building will not adversely affect the CCW f
pumps and will not adversely affect the plant's ability to achieve and maintain post-fire
~
As noted in the enclosed SE, during its review of the unresolved inspection items, the staff could not determine what level of fire damage to the hogging air ejector was assumed by
~~- Cons~mers in its_ analysis or the level of repairs needed to restore its\\°perability. Because (

October 14, 1997 the hogging air ejector is relied upon for continued secondary side heat removal and to transition the plant to cold shutdown, the* staff considers this to be a potential post-fire safe shutdown vulnerability which will be evaluated further in a future NRC inspection.
