• MAIN COOLANT SYSTEM 3/4.4.5 MAIN COOLANT SYSTEM LEAKAGE LEAKAGE DETECTION SYSTEMS LIMITING CONDITION FOR OPERATION 3.4.5.1. The following Main Coolant System leakage detection systems.shall be OPERABLE:

a. At least one containment atmosphere particulate monitoring system.

b. The containment drain tank level monitoring system.

c. The incore detection system thimble leak alarm system.

d. The neutron shield tank telltale leakage detection system.

APPLICABILITY: MODES 1, 2, 3, and 4.

ACTION

a. With the containment atmosphere particulate monitoring system inoperable, operation may continue for up to 7 days provided:

1. Main Coolant System water inventory balance is performed at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

2. The other above required leakage detection systems are OPERABLE, and

3. Appropriate grab samples are obtained and analyzed at least once per hour:

otherwise, 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 .t hin the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

b. With ' e c ntainment drain tank level monitoring system inoperable, rest e t'.e inoperable system to OPERABLE status within 7 days or be in at les H0'. 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 fo' owing 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

c. ' .th the incore detection system thimble leak alarm system inoperable, restore the leak alarm system to OPERABLE status within 7 days or close all thimble isolation valves; ret are the leak alarm system to OPERABLE status within 31 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 />.

d. With the neutron shicid tank telltale leakage detection system inoperable, restore the inoperable system to OPERABLE status within 7 days or open VD-V-1109 to restore to-OPERABLE status as part of the containment drain tank level monitoring system.
