LIMITING CONDITION FOR OPERATION' 3.3.4.1 The anticipated transient without scram recirculation pump trip (ATVS-RPT) system instrumentation channels shown in Table 3.3.4.1-1 shall be OPERABLE with their trip setpoints set consistent with the values shown in the Trip Setpoint column of Table 3.3.4.1-2.

APPLICABILITY: OPERATIONAL CONDITION 1.-

/tCTION:

a. With an ATVS-RPT system instrumentation channel trip setpoint less conserva-tive than the value shown in the Allowable Value 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 value.-_ -- _ -_ _

SURVEILLANCE REOUIREMENTS 4.3.4.1.1 Each ATWS-RPT system instrumentation channel shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL FUNCTIONAL TEST-and CHANNEL CALIBRATION

• operations at the frequencies shown'ir. Table 4.3.4.1-1.

4.3.4.1.2 LOGIC SYSTEM FUNCTIONAL TESTS and simulated automatic operation of all channels shall be performed at least once per.18 months.
