- k INSTRUMENTATION LIMITING CONDITION FOR OPERATION (Continued)
An OPERABLE quadrant symmetric incore detector segment group shall consist of 0
a minimum of three OPERABLE rhodium incore detector se#ments in 90 symmetric fuel assemblies.
APPLICABILITY: Whro the incore detection system is used for:
a.
Monitoring the AZIMUTHAL POWER TILT, b.
Recalibration of the excore neutron flux detection system, or c.
Monitoring the UNRODOED PLANAR RADIAL PEAXING FACTOR, the UNRODDED INTEGRATED RADIAL PEAKING FACTOR, or the linear heat rate.
ACTION:
With the incore detection system inoperable, do not use the system for the above applicable monitoring or calibration functions.
The provisions of specification 3.0.3 and 3.0.4 are not applicable.
SURVEILLANCE RE0VIREHENTS 4.3.3.2 The incore detection system shall be demonstrated OPERABLE:
a.
By performance of a CHANNEL CHECK within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to its use and at least once per 7 days thereafter when required for:
1.
Monitoring the AZIMUTHAL POWER TILT.
2.
Recalibration of the excore neutron flux detection system.
3.
Monitoring the UNRODDED PLANAR RADIAL PEAKING FACTOR, the UNRODDED INTEGRATED RADIAL PEAKING FACTOR, or the linear heat rate.
b.
At least once per refueling interval by performance of a CHANNEL l
CALIBRATION operation which exempts the neutron detectors but includes all electronic components.
The neutron detectors shall be calibrated prior to installation in the reactor core.
