INSTRUMENTATION INCORE DETECTION SYSTEM LIMITING CONDITIONS FOR OPERATION 3.3.3.2 The incore detection system shall be OPERABLE with:

a. At least twelve (12) neutron detector thimbles OPERABLE.
b. A minimum of two (2) OPERABLE neutron detector thimbles per core quadrant, and
c. Sufficient OPERABLE movable neutron detectors, drive and readout equipment to map these thimbles.

APPLICABILITY: When the incore detection system is used for core power distribution measurements.

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 REQUIREMENTS 4.3.3.2 The incore neutron detectors shall be demonstrated OPERABLE by normalizing each detector output to be used 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 for core power distribution measurements.
