The automatic bypass setpoint must be verified periodically to be > 10% RTP. If the RN )or power setpoint is nonconservat1ve, then the RN is considered inoperable. Alternately, the low power setpoint channel can be placed in the conservat1ve condition (nonbypass). If placed in the nonbypassed condition, the SR is met and the RN is not considered inoperable.

RPS Instrumentation B 3.3.1.1 BASES SURVEILLANCE SR 3.3.1.1.15 REQUIREMENTS (continued) This SR ensures that scrams initiated from the Turbine Stop Valve - Closure and Turbine Control Valve Fast Closure, Trip Oil Pressure - Low Functions will not be inadvertently bypassed when THERMAL POWER is a 30'I RTP. This involves calibration of the bypass channels (PIS-1-81A, PIS-1 418, PIS-1-91A; and P IS-'I-91B). Adequate margins for the instrument setpoint methodologies are incorporated into the actual setpoint.

lf any bypass channel's setpoint is nonconservative (i.e., the Functions are bypassed at a 30% RTP, either due to open main turbine bypass valve(s) or other reasons), then the affected Turbine Stop Valve - Closure and Turbine Control Valve Fast Closure, Trip Oil Pressure - Low Functions are considered inoperable. Alternatively, the bypass channel can be placed in the conservative condition (nonbypass). If placed in. the nonbypass condition (Turbine Stop Valve - Closure and Turbine Control Valve Fast Closure, Trip Oil Pressure - Low Functions are enabled), this SR is met and the channel is considered OPERABLE.

REQUIREMENTS any control rod is withdrawn at s 10% RTP in MODE 2. As noted, SR 3.3.2.1.3 is not required to be performed until 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months after THERMAL POWER is reduced to s 10% RTP in MODE 1.

This allows entry into MODE 2 for SR 3.3,2.1.2, and THERMAL POWER reduction to s 10% RTP for SR 3.3.2.1.3, to perform the required Surveillance if the 92 day Frequency is not met per SR 3,0.2. The 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months allowance is based on operating experience and in consideration of providing a reasonable time in which to complete the SRs. The Frequencies are based on reliability analysis (Ref. 8).

SR 3.3.2.1.4 A CHANNEL CALIBRATIONis a complete check of the instrument loop and the sensor. This test verifies the channel responds to the measured parameter within the necessary range and accuracy. CHANNEL CALIBRATIONleaves the channel adjusted to account for instrument drws between successive calibrations consistent with the plant speciTic setpoint methodology.

As noted, neutron detectors are excluded from the CHANNEL CALIBRATIONbecause they are passive devices, with minimal drift, and because of the difficultyof simulating a meaningful signal. Neutron detectors are adequately tested in SR 3.3,1.1.2 and SR 3.3.1.1.7.

Zf The Frequency is based upon the assumption of an month calibration interval in the determination of the magnitude of equipment drift in the setpoint analysis.

Controf Rod Block Instrumentation 8 3.3.2.1 BASES SURVEILLANCE SR 3.3.2.1.8 REQUIREMENTS (continued) The RBM setpoints are automatically varied as a function of power. Three Allowable Values are specified in Table 3.3.2.1-1 and the COLR, each within a specific power range. The powers at which the control rod block Allowable Values automatically change are based on the APRM signal's input to each RBM channel. Below the minimum power setpoint, the RBM is automatically bypassed. These power Allowable Values must be veriTied periodically to be less than or equal to the specified values. If any power range setpoint is nonconservative, then the affected RBM channel is considered inoperable.

Alternatively, the power range channel can be placed in the conservative condition (i.e., enabling the proper RBM setpoint).

lf placed in this condition, the SR is met and the RBM channel is not considered inoperable. As noted, neutron detectors are excluded from the Surveillance because they are passive devices, with minimal drift, and because of the difficultyof simulating a meaningful signal. Neutron detectors are ad uately tested in SR 3.3.1.1.2 and SR 3.3.1.1.7. The .
