• MAINE YANKEE ATOMIC POWER COMPANY B. Whenever the reactor coolant system baron concentration is less than that required for a Hot Shutdown Condition (Condition 5), two high ]

pressure safety injection pump subsystems shall be operable.

Remedial Action: If any of the component subsystems specified in B

~

above becomes inoperable, the operable component subsystem performing ]

the same function in the other train shall be tested within two hours ]

and the inoperable system must be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of the discovery of the nonconforming condition.

C. The following equipment must be operable whenever the reactor is in a Power Operation Condition (Condition 7): ]

1. Three safety injection tanks set for automatic initiation and subject to the conditions specified in A.1 above.

2 2. Two operable and redundant ECCS trains, each train consi. sting of the subsystems specified in A.2 above.

3. Station service power in accordance with Technical Specification 3.12.B.

1

4. The refueling water storage tank and the spray chemical addition tank filled and available in accordance with Technical Specification 3.7.

5. The fill header motor operated root valves to three non-isolated loops.

Exceptions:

1. One safety injection tank may be isolated for a period not to exceed one hour.

Remedial Actions:

1. If any of the component subsystems specified in C.2 above becomes inoperable, the operable component subsystem performing the same function in the other train shall be tested within ]

two hours and the inoperable system must be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of the discovery of the

. nonconforming condition.

2. If any of the fill header motor operated root valves become

! inoperable both of the other root valves shall be tested operable within two hours and the inoperable valves shall be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of the discovery of the nonconforming condition.

3. If one of the safety injection tanks is found not to be within specifications it shall be restored to specification within four hours.
