tltnclosure 2 ELECTRICAL POWER SYSTEMS 3/4.8.2 ONSlTE POWER DISTRIBUTION SYSTEMS ELECTRIC POWER MONITORING FOR REACTOR PROTECTION SYSTEM LIMITING CONDITION FOR OPERATION
_3~-8 *. 2.7 The po\\'ler mo"riitoring systeru. for the in service RPS MG set or
- Alternate Source shall be OPERABLE.*
APPLICABILITY:
CONDITIONS 1 and 2.
ACTION~
_With the. power monftoripg system for the in service RPS MG set or Alter*nate
- source inoper.able~ **re.store *the inoperable power monitoring system to OPERABLE status within 30 minutes or remove the RPS MG set or Alternate Source associated with the inoperable power monitoring system from service. One
.channel of a power monitoring system may be inoperable, as necessary for test or maintenance,c not-* to exceed 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />s/month.
SURVEILLANCE REQUIREMENTS 4.8.2.1 The above specilied RPS power*monitoring system instru~entation s~all
- be determined OPERABLE:
- a.
At least once per six months by performing a CHANNEL FUIKTIOf~AL TEST; and
- b.
At-~east once per.operating cycle by demonstrating the OPERABILITY of over-voltage, under-voltage and under~frequency protecti~e instrumentation.by performance of a CHANNEL CALIBRATION including simulated automatic actuation of the protective relays, tripping logic and output circuit breakers and verifying the following setpoints.
- 1.
Over-voltage_~_ VAC,.
- 2.
Under-voltage~ __ VAC,. and
- 3. Under-frequency ~---Hz.
