ELECTRICAL POWER SYSTEMS 3/4.8.4 ELECTRICAL E UIPMENT PROTECTIVE DEVICES MOTOR-OPERATED VALVES THERMAL OVERLOAD PROTECTION BYPASS DEVICES LIMITING CONDITION FOR OPERATION 3.8.4 The thermal overload protection bypass
- devices, integral with the motor
- starter, of each valve listed in Table 3.8-1 shall be OPERABLE.
APPLICABILITY:
Whenever the motor-operated valve is required to be OPERABLE.
ACTION:
With one or more of the thermal overload protection bypass devices inoperable, declare the affected valve(s) inoperable and apply the appropriate ACTION Statement(s) for the affected valve(s).
SURVEILLANCE RE UIREMENTS 4.8.4 The above required thermal overload protection bypass devices shall be demonstrated OPERABLE.
a.
At least once per 18 months, by visually verifying the bypass switch to be in the bypass position for those thermal overload devices which are either:
1.
Continuously bypassed and temporarily placed in force only when the valve motors are undergoing periodic or maintenance
- testing, or 2.
Normally in force 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 25K of:
1.
All thermal overload devices which are not bypassed, such that each non-bypassed 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 over load 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.
