conservative than the value shown in the Allowable Values column of i Table 3.3.3-2, declare the channel inoperable until the channel is
restored to OPERABLE status with its trip setpoint adjusted

! consistent with the Trip Setpoint value.

SURVEILLANCE RE0VIREMENTS

! 4.3.3.1 Each ECCS actuation instrumentation channel shall be demonstrated 1 OPERABLE by the performance of the CHANNEL CHECK, CHANNEL FUNCTIONAL TEST and CHANNEL CALIBRATION operations for the OPERATIONAL CONDITIONS and at the frequencies shown in Table 4.3.3.1-1.

Each test shall include at least one channel per trip system such that all channels are tested at least once every N times 18 months where N is the total number of redundant channels

in a specific ECCS trip system.
  • For the diesel generator output breakers: Completion of logic system functional testing, for the loss of power function, to positively verify that the breaker reclosure permissive relay (52XX) is re-energized by the associated bus load shedding logic contact closing, rather than the 52XX being

. re-energized by a parallel path, may be deferred and must be completed no later than during the first plant outage after September 29, 1995.

{ 6. Verifying the diesel generator is aligned to provide standby j power to the associated emergency busses.

7. Verifying the pressure in all diesel generator air start receivers to be greater than or equal to 215 psig.

l

'All diesel generator starts for the purpose of this Surveillance Requirement may be preceded by an engine prelvbe period. The diesel generator start 3 (10 sec) from ambient conditions shall be performed at least l 4 once per 184 days in these surveillance tests. All other engine starts for the purpose of this surveillance testing may be preceded by other warmup procedures recommended by the manufacturer so that the mechanical stress and wear on the diesel engine is minimized.
