A Note to SR 3.3.1.1.9 and SR 3.3.1.1.13 states that neutron detectors are excluded from CHANNELCALIBRATIONbecause they are passive devices, with minimal drift, and because of the difficultyof simulating a meaningful signal.
Changes in neutron detector sensitivity are compensated for by performing the 7 day calorimetric calibration (SR 3.3.1.1.2) and the 1000 MWD/TLPRM calibration against the TIPs (SR 3.3.1.1.7).
A second Note for SR 3.3.1.1.9 is provided that requires the IRM SRs to be performed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of. entering MODE 2 from MODE 1. Testing of the MODE 2 IRM Functions cannot be performed in MODE 1 without utilizingjumpers, lifted leads, or movable links. This Note allows entry into MODE 2 from MODE 1 ifthe associated Frequency is not met per SR 3.0.2.
Twelve hours is based on operating experience and in consideration of providing a reasonable time in which to complete the SR.
The Frequency of SR 3.3.1.1.9 is based upon the assumption of a 92 day calibration interval in the determination of the magnitude of equipment drN in the setpoint analysis.
The Frequency of SR 3.3.1.1.10 is based upon the assumption of a 184 day calibration interval in the determination of the magnitude of equipment drift in the setpoint analysis.
The Fre u cy of SR 3.3.1.1.13 is based upon the assumption of an 8

SR 3.3.1.1.15 This SR ensures that scrams initiated from the Turbine Stop Valve - Closure and Turbine Control Valve Fast Closure, Trip Oil Pressure - Low Functions willnot be inadvertently bypassed when THERMALPOWER 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.
lfany 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).
Ifplaced 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.

Controf Rod Block Instrumentation 8 3.3.2.1 BASES SURVEILLANCE REQUIREMENTS (continued)
SR 3.3.2.1.8 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.
Ifany 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).
lfplaced 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 1
