3/4 LIMITING CONDITIONS FOR OPERATION AND SURVEILLANCE REQUIREMENTS 3/4.7 PLANT SYSTEMS 3/4.7.5 CONTROL ROOM VENTILATION SYSTEM CONTROL ROOM EMERGENCY VENTILATION SYSTEM LIMITING CONDITION FOR OPERATION 3.7.5.1 The control room emergency ventilation system (CREVS) shall be OPERABLE with:
- a.
Two independent pressurization trains, and
- b.
One charcoal adsorber/HEPA filter unit.
The control room envelope/pressure boundary may be opened intermittently under administrative control.
APPLICABILITY:
MODES 1, 2, 3, 4, and during the movement of irradiated fuel assemblies.
ACTION:
MODES 1, 2, 3, and 4:
- a.
With one pressurization train inoperable, restore the inoperable train to OPERABLE status 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 />.

During the movement of irradiated fuel assemblies:
- d.
With one pressurization train inoperable, restore the inoperable pressurization train to OPERABLE status within 7 days, or initiate and maintain operation of the remaining OPERABLE train in the pressurization/cleanup alignment.
- e.
With any of the following: (1) both pressurization trains inoperable; (2) the filter unit inoperable; or (3) the control room envelope/pressure boundary inoperable, immediately suspend all operations involving the movement of irradiated fuel assemblies.
- f.
The provisions of Specification 3.0.4 are not applicable to movement of irradiated fuel assemblies.
