ELECTRICAL POWER SYSTEMS HOTOR-OPERATED VALVES THERMAL OVERLOAD PROTECTION AND BYPASS DEVICES LIMITING CONDITION FOR OPERATION 3.8.4.2 The thermal overload protection and bypass devices, integral with the motor sisrter, of each valve used in safety systems shall be OPERABLE.
l APPLICAB !ITY:
Whenever the motor operated valve is required to be OPERABLE.
ACTION:
With one or more of the thermal overload protection and/or bypass devices inoperable, declare the affected valve (s) inoperable and apply the appropriate ACTION Statement (s) for the affected valve (s).
SURVEILLANCE REQUIRjMSNT" 4.8.4.2 The above required thermal overload protection and bypass devices shall be demonstrated OPERABLE.
a.
At least once per 18 months, by the performance of a CHANNEL FUNCTIONAL TEST of the bypass circuitry for those thermal overload devices which are either:
).
Continuously bypassed and temporarily placed in force only when the valve motors are undergoing periodic or maintenance testing, or 2.
Normally orce during plant operation and bypassed under accident conditions.
b.
At least once per 18 months by the performance of a CHANNEL CALIBRATION of a representative sample of at least 25% of:
1.
All thermal overload devices which are not bypassed, such that each nonbypassed device is calibrated at least once per 6 years.
2.
All thermal overload devices which are continuously bypassed and temporarily placed in force only when the valve motors are undergoing periodic or maintenance testing, and thermal overload devices normally in force and bypassed under accident conditions such that each thermal overload is calibrated and each valve is cycled through at least one complete cycle of full travel with the motor-operator when the thermal overload is OPERABLE and not bypassed, at least once per 6 years.
