RESPONSE TO VERBAL REQUEST FOR ADDITIONAL INFOR.'* TION ON TECHNICAL ,

SPECIFICATION CHANGE REQUEST - STATION BATTERY SERVICE TEST NRC Staff review of Consumers Power Company submittal dated December 22, 1986 verbally requested additional information to complete the review. Attachments I to this letter provide the requested information.

Our submittal dated December ?2, 1986 requested a change to the Big Rock Point Technical Specifications to resolve a contradiction described in LER 86-004, j Since that submittal the station battery has been replaced due to age. Exide

  • EA-13 cells are now used as a replacement for the Exide EHGS-17 cells. A change was also made to the two hour service profile at that time to permit ,

leaving the DC Turbine Lube Oil Pump on for two hours instead of 30 minutes.

Attachment 1 to this letter provides a copy of the design calculations used to

support this change. The DC Turbine tube 011 Pump was not left on for the r full 121 uinutes of the duty cycle. Adding the additional minute would have required the next larger size cell and additional DC system changes.

a l To ensure that the needed battery capacity is retained to restore station  !

I power, procedural steps are still retained to require removing the DC 011 Pump 4

from service after turbine coastdown. Attachment 2 provides a copy of off-normal procedure 2.36 "Loss of Station Power" which provides this guidance. ;

The current revision still specifies 30 minutes; however, a change is in progress which will state two hours.
