INSTRUMENTATION END-OF-CYCLE RECIRCULATION PliMP TRIP SYSTEM INSTRUMENTATION LIMITING CONDITION FOR OPERATION 3.3.4.2 The end-of-cycle recirculation pump trip (EOC-RPT) system instrumentation channels shown in Table 3.3.4.2-1 shall be OPERABLE with their trip setpoints set consistent with the values shown in the Trip Setpoint column of Table 3.3.4.2-2 and with the END-OF-CYCLE RECIRCULATION PUMP TRIP SYSTEM RESPONSE TIME as shown in Table 3.3.4.2-3.
APPLICABILITY: OPERATIONAL CONDITION 1, when THERMAL POWER is greater than or equal to 30% of RATED THERMAL POWER.
ACTION:
With an end-of-cycle recirculation pump trip system instrumentation a.
channel trip setpoint less conservative than the value shown in the Allowable Values column of Table 3.3.4.2-2, declare the channel inoperable until the channel is restored to OPERABLE status with the channel setpoint adjusted consistent with the Trip Setpoint value.
b.
With the number of OPERABLE channels one less than required by the Minimum OPERABLE Chanrsels per Trip System requirement for one or both trip systems, place the inoperable channel (s) in the tripped condition within one hour.
With the nmber of OPERABLE channels two or more less than required c.
by the Mini'um OPERABLE Channels per Trip System requirement for one trip system and:
1.
If the inoperable channels consist of one turbine control valva channel and one turbine stop valve channel, place both inoperable channels in the tripped condition within one hour.
2.
If the inoperable channels include two turbine control valve channels or two turbine stop valve charcels, declare the trip system inoperable.
