• 2. 0 LIMITING CONDITIONS FOR OPERATION r

2.12 Control Room Systems Applicability 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.

Specifications (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 four hours, the reactor vill 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 vill be observed during hot functional testing to determine local temperatures and monitored during operation if normal plant ventilation is not available.

(b) From 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 />.

Sasis The reactor protective system and the engineered safeguards system were designed for and the instrumentation was tested at 120 0F, Therefore, if the temperature of the control room exceeds 1200F, the reactor vill be shutdown and the conditions corrected to preclude failure of components in an untested environment.

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

If the system cannot be repaired within seven (i) days, the reactor is shutdown zad brought to cold shutdown within 2h hours.
