Dear Mr. Davis:

This special report is being submitted in accordance with Technical Specification 3.7.10 action a, to inform you that the following four fire suppression components have been inoperable longer than allowed by Technical Specification 3.7.10 action a.

Fire detection in the Unit Two CD Emergency Diesel Generator Room was declared inoperable on January 29, 1990 due to a failed circuit board in the A.C.

inverter which supplies the detection circuit.

Replacement parts for the inverter are no longer available. A plant modification has been initiated to replace the old inverter with an available equivalent circuit. It is anticipated that the plant modification will be'ompleted and the detection restored to operability by April 24, 1990.

A fire watch, as required by Technical Specification 3.7.10 action a, will be maintained while the fire detection is inoperable.

lj) Fire Door 391 was declared inoperable on February 2, mU 1990 due to the door being removed for replacement.

(ci(QA

-OL Rc It was restored to operability on February 15, 1990. A fire watch, as required by Technical GG au~~

gwG Specification 3.7.10 action a, was maintained while the door was inoperable.

GQ GI-I Fire Dampers 1-HV-AC-FD-l, 1-HV-AC-FD-2, 1-HV-AC-FD-3, iNK 2-HV-AC-FD-1, 2-HV-AC-FD-2, and 2-HV-AC-FD-3,

('s located in the Unit One and Unit Two P-250 Computer GK op Rooms were declared inoperable on February 8, 1990 o.k0) when they failed to automatically close during 0

U.S. Nuclea gulatory Commission March 8, 199 Page 2 of 2 surveillance testing. An engineering evaluation is being performed to determine the reason for the failures and,the proper repairs or replacements, necessary. We will inform you via a follow up if report when the engineering evaluation is complete and the dampers have been restored to operability.

A fire watch, as required by Technical Specification 3.7.10 action a, is being maintained while the dampers are inoperable.

Fire Damper 1-HV-AQT-W2, located in the Unit One Reactor Cable Tunnel Quadrant 2 was declared inoperable on February 15, 1990 when it failed to fully close during a surveillance test. Repair activities on the damper have been temporarily suspended due to the inaccessability of the damper operating mechanism. A plant modification has been initiated to install a service port on the ventilation ductwork associated with the damper to allow repair activities to continue. We will inform you through a follow-up report when the plant modification is complete and the damper has been declared operable.

The damper will be maintained in a closed position until repair activities have been completed.
