Attochment 1 Specification LCO 4.10.2 - Halon Fire Suppression System, Three Room Control Complex, Limiting Condition for Operation The Halon Fire Suppiassion system for the control room, auxiliary electric room, and the 480 volt switchgear room shall be operable during reactor power operation. If the Halon system becomes inoperable and cannot be made operable within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, the reactor shall be shutdown in an orderly manner.
Basis for Specification LCO 4.10.2 The Halon system provides fire suppression capability for the control roon, auxiliary elettric room, and the 480 volt switchgear room. Halon is a non-toxic, halogsnated c emical fire suppressant. The Halen system is a total flooding extinguishing system divided into three sections. One section supplies the 480 volt switchgear room, the second section supplies the control room, and the third the auxiliary electric toom. Total flooding of these areas with halon will extinguish an active fire without requiring abandonment of the area.
The auxiliary electric room Halon System Section is automatically initiated by the simultaneous actuation of a detector in zone #2 and #3 of Table 4.10-3; the 480 volt room Halon System Section is automatically initiated by the simultaneous actuation of a detector in fire detection zone #5 and #6 of Table 4.10-3.
The Halon System Section for the 480 volt switchgear room may be manually initiated by a switch located just outside the door of the room. The Halon System for the auxiliary electric room may be manually initiated by a switch .
located just outside of the room. The Halon System Section of the control room is manually initiated by a switch located in the control room. In the event ,
that electrical power is not available to initiate Halon System operation, each Halon storage bottle is provided with a manually operated release mechanism i
which will release the bottle contents when operated.

Attachment 2 Specification LCO 4.10.3 - Smoke Detectors and Alarms for Three Room Control Complex and Congested Cable Areas, Limiting Condition for Operation The reactor stall not be operated at power unless the minimum number of smoke detectors for each of the zones listed in Table 4.10-3 are operable.
If the minimum number of detectors of each zone are not operable, the following actions shall be taken:
An individual shall.be designated to inspect the area or areas with inoperable detectors once per hour.
The inoperable detectors shall be made operable within thirty (30) days or the reactor shall be shut down in an orderly manner.
~
Basis for Specification LCO 4.10.3 The smoke d'etection and alarm system provides detection and alarm capa-bility for the control room, auxiliary electric room, the 480 volt switch gear room, the congested cable areas located at the "G" and "J" column rows and selected reactor building HVAC return air ducts in various areas which are not normally manned.
In addition the system will automatically initiate operation of the Halon
- fire suppression system in the auxiliary electric room or the 480 volt switch- .
gear room upon actuation of a detector in both of the zones in each room.
The system alerts the operator to the possibility of a fire in the con-gested cable areas and to the necessity of investigation of conditions in these areas.

If the spray systems become inoperable and cannot be made operable within 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br />, the reactor shall be shut down in an orderly manner.
Basis for Specification LCO 4.10.5 The fixed water spray systems provide backup fire suppression in the congested j cable areas. In the 480 volt switchgear room and the auxiliary electric room, the systems are a backup to the installed Halon system. If the fixed water spray systems were inoperable, the smoke detectors and alarm system of LCO 4.10.3 would be available for detection and alarm of a fire. In all areas where it is installed the fixed water spray system is a backup to normal fire fighting techniques.
