Applies to the control room air conditioning and filtering systems. l Objective To limit. the environmental conditions in the control room, under normal and post DBA conditions.

I Speci fic ations (1) If the ' control room air temperature reaches 1200F, immediate action shall be taken to reduce this temperature. If the temperature cannot be reduced to. below 1200F in f0ur hours ,

the reactor vill be placed in a hot shutdown condition.

(2) A thermemeter must be in the control room at all times.

(3) All areas of the plant which have safety related instrumentation vill be observed durin6 hot functional testing to determine local temperatures and monitored during operation if normal plant ventilation is not available.

(b) Frem and after the date that the control room air. treatment system is made or found to be inoperable for any reason, reactor operation is permissable only during the succeeding seven days unless such circuit is sooner made operable. If these conditions cannot be met, the reactor shall be placed in cold shutdown condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Basis The reactor protective system and the engineered safeguards system were designed for and the instrumentation was tested at 120 0F,

' herefore, if the temperature of the centrol room exceeds 1200F, thc reactor vill be shutdown and the conditions corrected to preclude failure of components in an untested environment.

r the centrol room air treatment system is found to be inoperable ,

there is no immediate threat to the control room and reactor opera-tion may centinue for a limited period of time while repairs are being made. If the system cannet be repaired within seven (7) days, the reactor is shutdown and brou6ht to cold shutdown within 2h hours.

Applies to the control room air conditioning and filtering systems, j Ob.iective To limit the environmental conditions in the control room, under normal  :

and post DBA conditions. '

Soecifications ,

i (1) If the control room air temperature reaches 120*F, immediate action  !

shall be taken to reduce this temperature. If the temperature cannot be reduced to below 120'F in four hours, the reactor will be placed in a hot shutdown condition.

(2) A thermometer must be in the control room at all times.

(3) All areas of the plant which have safety related instrumentation will be observed during. hot functional testing to determine local-temperatures and monitored during operation if normal plant ventilation is not available.

(4) With one control room air filtration system inoperable, restore the inoperable system to operable status within 7 days or be in at least ,

cold shutdown condition within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. '

Basis '

The reactor protective system and the engineered safeguards system were designed for and the instrumentation was tested at 120*F. Therefore, if the temperature of the control room exceeds 120*F, the reactor will be shutdown and the conditions corrected to preclude failure of components in an untested environment. '

If the control room air temperature system is found to be inoperable, f there is no immediate threat to the control room and reactor operation

'may continue for a limited period of time while repairs are being made.

If the system cannot be repaired within seven (7) days, the reactor is shutdown and brought to cold shutdown within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
