INSTRUMENTATION TRAVERSING IN-CORE PROBE SYSTEM LIMITING CONDITION FOR OPERATION 3.3.7.7.

The traversing in-core probe system shall be OPERABLE with:

a.

Five movable detectors,

drives, and readout equipment to map the core, and b.

Indexing equipment to allow all five detectors to be calibrated in a common location; otherwise:

with four traversing in-core probe machines, an inaccessible LPRM string may be calibrated using a traversing in-core probe scan from a symmetric string provided that an 'A'ype control rod pattern is in use and that the total core TIP asymmetry is less than 6X (standard deviation).

APPLICABILITY:

When the traversing in-core probe is used for:

a.

Recalibration of the LPRM detectors, and b.*

Monitoring the

APLHGR, LHGR, MCPR, or MFLPD.

ACTION:

With the traversing in-core probe system inoperable, suspend use of 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 RE UIREMENTS 4.3.7.7 The traversing in-core probe system shall be demonstrated OPERABLE by normalizing each of the above required detector outputs within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> prior to use for the above applicable monitoring or calibration functions.
