EMERGENCY CORE COOLING SYSTEM ACTUATION INSTRUMENTATION ACTION ACTION 30 - With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Trip Function requirement:

ADS trip system 8. With one channel inoperable, place the inoperable Channel or ECCS in the tripped condition within one hour or declare the l W r inoperable,

b. ssociated"han fth more t one channel inoperable, declare the associated jer 4eo inoperable.

ACTION 31 - With tre number of OPERABLE channels less than required by the Minimun OPERABLE Channels per Trip Function requirement, declare the associated ADS trip system or ECCS inoperable.

ACTION 32 -

With the number of OPERABLE channels less than the Minimum CPERABLE Channels per Trip Function requirement, place the inoperable channel in the tripped condition within one hour.

ACTION 33 - With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Trip Function requirement, restore the inoperable channel to O RPBLE status within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or declare the associated AD3F:9dp__fCCS inoperable.

ACTION 34 - With the number of OPERABNS64 Ness than required by the Minimum OPERABLE Channels per Trip Function requirement:

a. For one trip system, place that trip system in the tripped i

condition within one hour or declare the HPCS system inoperablel

b. For both trip systems, declare the HPCS system inoperable.

ACTION 35 - With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Trip Function requirement, place at least one inoperable channel in the tripped condition within one hour, or ali

ACTION 36 With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Trip Function requirement, place at least one inoperable channel in the tripped condition within one hour or declare the HPCS system inoperable. ,

1 ACTION 37 - With the number of OPERABLE channals less than the Total Number of Channels, declare the associated emergency diesel gensrator inoperable and take the ACTION required by Specification 3.8.1.1 or 3.8.1.2, as appropriate.

ACTION 38 - With the number of OPERABLE channels less than the Total Number of Channels, place the inoperable channel in the tripped condi-tion within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />; operation may then continue until perform- l ince of the next required CHANNEL FUNCTIONAL TEST.

ACTION 39 With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Trip Function requirement, place the inoperable channel in the tripped condition within one hour.

Restore the inoperable channel to OPERABLE ctatus within 7 days or declare the associated system inoperable.
