AmROLLED eV dhZR REACTOR COOLANT SYSTEM 3/4.4. 10 REACTOR COOLANT SYSTEM VENTS LIMITING CONDITION FOR OPERATION 3.4. 10 Both reactor coolant system vent paths shall be OPERABLE and closed at each of the following locations:

a. Reactor vessel head, and

b. Pressurizer steam space.

APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

With only one of the above required reactor coolant system vent paths OPERABLE, from either location restore both paths at that location to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> 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 HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

With none of the above required reactor coolant system vent paths OPERABLE, from either location restore at least one path at that location to OPERABLE status within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or be in at least HOT STANDBY within the next 6 nours and in HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

SURVEILLANCE REOUIREMENTS 4.4. 10 Each reactor coolant system vent path shalJ be demonstrated OPERABLE at least once per 18 months, when in MODES 5 or 6~by:

a. Verifying all manual isolation valves in each vent path are locked in the open position.

b.. Cycling each vent through at least one complete cycle from the control room.

c. Verifying flow through the reactor coolant system vent paths during venting.
