I 3/4.3.3 EMERGENCY CORE COOLING SYSTEM ACTUATION INSTRUMENTATION I l

LIMITING CONDITION FOR OPERATION i 3.3.3 The emergency core cooling system (ECCS) actuation instrumentation l channels shown in Table 3.3.3-1 shall be OPERABLE with their trip setpoints ,

set consistent with the values shown.in the Trip Setpoint column of Table i 3.3.3-2. 1 APPLICABILITY: As shown in Table 3.3.3-1.

! ACTION:

a. With an ECCS actuation instrumentation channel trip setpoint less ,

conservative than the value shown in the Allowable Values column of Tame 3.3.3-2, declare the channel inoperable until the channel  !

is restered to OPERABLE status with its trip setpoint adjusted '

l consifient with the Trip Setpoint value.

! 1 l b. With one or more ECCS actuation instrumentation channels )

inoperable, take the ACTION required by Table 3.3.3-1. '

l

c. With either ADS trip system "A" or "B" inoperable, restore the inoperable trip system to OPERABLE status within: )

1. 7 days, provided that the HPCI and RCIC systems are OPERABLE, otherwise,  ;

• For the diesel generator output breakers: Completion of logic system l 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.
