CONTROLLED COPY INSTRUMENTATION 3/4.3.4 RECIRCULATION PUMP TRIP ACTUATIOH INSTRUMENTATION A'WS RECIRCULATION PUMP TRIP SYSTEM INSTRUMENTATION lIMITING CONDITION FOR OPERATION 3.3.4.1 The anticipated transient without scram recirculation pump trip (ATMS-RPT) system instrumentation channels shown in Table 3.3.4.1-1 shall be OPERABLE with their trip setpoints set consistent with values shown in the Trip Setpoint column of Table 3.3.4. 1-2.

APPLICABIlITY: OPERATIONAL CONDITION l.

ACTION:

'a 0 Mith an AVOWS-RPT system instrumentation channel trip setpoint less conservative than the value shown in the Allo~able -Values column of Table 3.3.4.1-2, declare the channel inoperable until the channel is restored to OPERABLE status with the channel trip setpoint adjusted consistent with the Trip Setpoint t- value+

b. the number of OPERABLE channels~rhqless 'ith than required by the Minimum OPERABLE Channels per Nip+stem requirement 4or one-4r-ip-p lt'.)

OPERABLE status within 14 da s ~be in at Bth<~ ega<,

least STARTUP within the".next hours.
