f lNSTRUMENTATION INCORE DETECTORS LIMITING CONDITION FOR OPERATION _

3.3.3.2 The incore detection system shall be OPERABLE with:

a. At least 75% of all incore detector locations, and 1

b. A minimum of two quadrant symmetric incore detector locations per core quadrant, and

c. A minimum of 9 OPERABLE incore detector segments at each detector segment level.

An OPERABLE incore detector segment shall consist of an OPERABLE rhodium detector constituting one of the segments in a fixed detector string.

An OPERABLE incore detection location shall consist of a string in which at  !

least three of the four incore detector segments are OPERABLE.

APPLICABILITY: When the incore detection system is used for:

a. Monitoring the AZlHUTHAL POWER TILT,

b. Recalibration of the excore neutron flux detection system, or

c. Monitoring the TOTAL 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 specifications -

3.0.3 and 3.0.4 are not applicable.

SURVEILLANCE RE0VIREMENT 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 TOTAL UNRODDED INTEGRATED RADIAL PEAKING FACTOR or the linear heat rate.

b. At least .once per 18 months by performance of a CHANNEL 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.
