NOTICE OF DEVIATION The Cleveland Electric Illuminating License No. NPF-58 Company The following deviation was identified during an inspection conducted on October 12 through November 21, 1989:
Perry Nuclear Power Plant Updated Safety Analysis Report, Revision 1, dated March 1989, Section 9.2.2.3 stated that the Unit 2 emergency closed cooling system is used as the Seismic Category I backup cooling water supply to the fuel pool heat exchangers.
Further it was stated that:
(1) "The Unit 2 emergency closed cooling system will be available to provide fuel pool heat exchanger cooling water prior to Unit I refueling;" and (2) "Any time after the start of emergency closed cooling system operation, cooling may be restored to the fuel pool heat exchangers by remote-manual action from the control room."
Contrary to the above- (1) the Unit 2 emergency closed cooling system was notavailabletoprovIdefuelpoolheatexchangercoolingwaterpriorto Unit I ref t. iing, and (2) the system cross-connect from Unit 1 emergency service wat<. (current Seismic Category I backup) was not capable of being placed in service by remote-manual action from the control room.
As identified in System Operating Instructions (501)-G41, " Fuel Pool Cooling and Cleanup System," Revision 6, dated December 30,1988, and S01-P45/49,
" Emergency Service Water and Screen Wash Systems," Revision 0, dated August 22, 1989, the method utilized to provide a backup Seismic Category I source of fuel pool heat exchanger cooling was expected to take 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to implement.
In addition, those instructions required the selected Unit 1 emergency service water loop to be drained in order to remove " blind flanges." Draining of the selected Unit I emergency service water loop would make that loop incapable of performing other intended safety functions.
Please provide in writing within 30 days of the date of this Notice:
(1) the reason for the deviation; (2) the corrective steps which have been taken and the results achieved; (3) the corrective steps which will be taken to avoid further deviations; and (4) the date when your corrective action will be completed.
Where good cause is shown, consideration will be given to extending the response time.
