CIRCUIT PROTECTION DEVICES LIMITING CONDITION FOR OPERATION 3.8.4.3 Circuit breakers for non-Class 1E cables located in trays which do not have cable tray covers and which provide protection for cables that if faulted could cause failure in both adjacent, redundant Class 1E cables shall be OPERABLE.
APPLICABILITY:
All modes ACTION:
a.
With one or more of the above required non-Class 1E circuit breaker (s) inoperable, within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, either:
1.
Restore the circuit breaker (s) to OPERABLE status; or 2.
De-energize the circuit breaker (s); or 3.
Establish a one (1) hour roving fire watch for those areas in which redundant systems or components could be damaged.
~
b.
The provisions of Specification 3.0.4 are not applicable.
SURVEILLANCE REQUIREMEN'S T
4.8.4.3 The above required circuit breakers shall be demonstrated OPERABLE.
a.
At least once per eighteen (18) months:
- 1. x By verifying that the medium voltage (7.2 KV) circuit breakers.
are OPERABLE by selecting, on a rotating basis, at least 10% of the circuit breakers and performing the following:
(a) A CHANNEL CALIBRATION of the associated protective relays, and i
(b) An integrated system functional test which includes simulated automatic actuation of the system and verifying that each relay and associated circuit breakers and control circuits function as designed.
(c) For each circuit breaker found inoperable during these functi.onal tests, an additional representative sample of i
at least 10% of all the circuit breakers of the inoperable type shall also be functionally tested until no more failures are found or all circuit breakers of that type j -
have been functionally tested.

ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) 2.
By selecting and functionally testing a representative sample of at least ten percent (10%) of each type of lower voltage circuit breakers.
Circuit breakers selected for functional testing shall be selected on a rotating basis.
Testing of these circuit breakers shall consist of injecting a current in excess'of the breaker's nominal setpoint and measuring the response time.
The measured response time will be compared to the manufacturer's data to insure.that it is less than or equal to a value speci-fied by the manufacturer.
Circuit breakers found inoperable during functional testing shall be restored to OPERABLE status prior to resuming operation.
For each circuit breaker found inoperable during these functional tests, an additional repre-sentative sample of at least ten percent (10%) of all the circuit breakers of the inoperable type shall also be func-tionally tested until no more failures are found or all circuit breakers of that type have been functionally tested.
b.
At least once per sixty (60) months by subjecting each circuit breaker to an inspection and preventive maintenance in accordance with procedures prepared in conjunction with its manufacturer's recommendations.

BASES 3/4.8.4 ELECTRICAL EQUIPMENT PROTECTIVE DEVICES i
Containment electrical penetrations and penetration conductors are protected by either deenergizing circuits not required during reactor operation or by demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers during periodic surveillance.
The surveillance requirements applicable to lower voltage circuit breakers and fuses provide assurance of breaker and fuse reliability by testing at least one representative sample of each manufacturer's brand of circuit breaker and/or fuse.
Each manufacturer's molded case and metal case circuit breakers and/or fuses are grouped into representative samples which are then tested on a rotating basis to ensure that all breakers and/or fuses are tested.
If a wide variety exists within any manufacturer's brand of circuit breakers and/or fuses, it is necessary to divide that manufacturer's breakers and/or fuses into groups and treat each group as a separate type of breaker or fuses for surveillance purposes.
The OPERABILITY of the motor operated valves thermal overload protection and/or bypass devices ensures that these devices will not prevent safety-related valves from performing their function.
The Surveillance Requirements for' demonstrating the OPERABILITY of these devices are in accordance with Regulatory Guide 1.106, " Thermal Overload Protection for Electric Motors on Motor Operated Valves," Revision 1, March 1977.
The surveillance requ'irements of the circuit breakers for non-Class 1E cable.s located in trays which do not have cable tray covers and which provide protection for cables that, if faulted, could cause failure in both adjacent, redundant Class 1E cables ensures that the integrity of Class 1E cables is not compromised by the failure of protection devices to operate in the non-Class 1E cables.
