REACTOR COOLANT SYSTEM REACT 03 COOLANT SYSTEM LEAKAGE LIMITING CONDITION FOR OPERATION 1

3.4.6.2 Reactor Coolant System leakage shall be limited to:

a.

No PRESSURE BDUNDARY LEAKAGE, b.

1 GPM UNIDENTIFIED LEAKAGE, c.

1 GPM total prinary-to-secondary leakage through both steam generators and 0.5 GPM through any one steam generator, and d.

10 GPM IDENTIFIED LEAKAGE from the Reactor Coolant System.

APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

a.

With any PRES 5URE BOUNDARY LEAKAGE, be in COLD SHUTDOWN with-in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

b.

With any Reactor Coolant System leakage greater than any one of the above limits, excluding PRESSURE BOUNDARY LEAKAGE, reduce the leakage rate to within limits within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or be in COLD SHUTDOWN within the next 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.**
