PLANT SYSTEMS 3/4.7.6 CONTROL ROOM EMERGENCY VENTILATION SYSTEM LIMITING CONDITION FOR OPERATION 3.7.6.1 Two independent control room emergency ventilation systems shall be OPERABLE.
APPLICABILITY: ALL MODES ACTION:
Modes 1, 2, 3, and 4:
With one Control Room Emergency Air Clean up System inoperable, restore the inoperable system to OPERABLE statec within 7 days or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
MODES 5 and 6*:
l a.
With one Control Room Emergency Air Clean-Up System inoperable, restore the inoperable system to OPERABLE status within 7 days or 6
initiate and maintain operation of the remaining OPERABLE Control Room Emergency Air Clean-Up System in the recirculation mode, b.
With both Control Room Emergency Air Clean-Up Systems inoperable, or with the OPERABLE Control Room Emergency Air Clean-Up System required to be in the recirculation mode by ACTION (a.) not capable of being powered by an OPERABLE normal and emergency power source, l
suspend all operations involving CORE ALTERATIONS or positive reactivity changes.
In Modes 5 and 6, when a Control Room Emergency Air Clean-up system is determined to be inoperable solely becaen its emergency power source is inoperable, or solely because its normal pcwer source is inoperable, it may be considered OPERABLE for the purpose of_ satisfying the requirements of-3.7.6.1 Limiting Condition for Operation, provided:
(1)its corresponding normal'At emergency power source is OPERABLE; and (2) all of'its redundant system (s), subsystem (s), train (s), component (s) and device (s) are OPERABLE, or likewise satisfy the requirements of the specification.
Unless both conditions (1) and (2) are satisfied within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, then Limiting Condition for Operation (LCO) 3.1.6.1.a or 3.7.6.1.b shall be invoked as applicable.
