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 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.
