3/4.5 EMERGENCY CORE COOLING SYSTEMS (ECCS)
ACCUMULATORS LIMITING CONDITION FOR OPERATION 3.5.1 Each Reactor Coolant System accumulator shall be OPERABLE with:
- a.
The isolation valve open,
- b.
Between 7532 and 7802 gallons of borated water,
- c.
Between 2300 and 2600 ppm of boron, and
- d.
A nitrogen cover-pressure of between 585 and 665 psig.
APPLICABILITY:
MODES 1, 2 and 3.*
ACTION:
- a.
With one accumulator inoperable due to boron concentration not within limits, restore the inoperable accumulator to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
- b.
With one accumulator inoperable for reasons other than Action a, restore the inoperable accumulator to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
- c.
With either Action a or b not being completed within the specified completion
- time, 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 reduce pressurizer pressure to
< 1000 psig within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
SURVEILLANCE REQUIREMENTS 4.5.1 Each accumulator shall be demonstrated OPERABLE:
- a.
At least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> by:
- 1.
Verifying the contained borated water volume and nitrogen cover-pressure in the tanks are within limits, and
- 2.
Verifying that each accumulator isolation valve is open.
- Pressurizer Pressure above 1000 psig.

EMERGENCY CORE COOLING SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)
- b.
At least once per 31 days and, for only the affected accumulator, within 6
hours after each solution volume increase that is not the result of addition from the refueling water storage tank of greater than or equal to 1%
of accumulator volume, by verifying the boron concentration of the accumulator solution.
- c.
At least once per 31 days when the RCS pressure is above 1000 psig by verifying that power to the isolation valve operator control circuit is disconnected by removal of the plug in the lock out jack from the circuit.
