1.0 DEFINITIONS

]

The following terms are defined so that uniform interpretation of these specifications may be l

l achieved. The defined terms appear in capitalized type and shall be applicable throughout these Technical Specifications.

ACTION ACTION shall be that part of a Specification which prescribes remedial measures required under l

designated conditions.

i l

AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR)

The AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) shall be applicable to a specific planar height and is equal to the sum of the LINEAR HEAT GENERATION RATE (s) for i

all the fuel rods in the specified bundle at the specified height divided by the number of fuel rods in the fuel bundle.

CHANNEL A CHANNEL shall be an arrangement of a sensor and associated components used to evaluate l

plant variables and generate a single protective action signal. A CHANNEL terminates and loses its identity where single action signals are combined in a TRIP SYSTEM or logic system.

CHANNEL CAllBRATION l

A CHANNEL CAllBRATION shall be the adjustment, as necessary, of the CHANNEL output l

such that it responds with the necessary range and accuracy to known values of the parameter i

i which the CHANNEL monitors. The CHANNEL CAllBRATION shall encompass the entire

(

CHANNEL including the required sensor and alarm and/or trip functions, and shall include the 1

l CHANNEL FUNCTIONAL TEST. The CHANNEL CALIBRATION may be performed by any series i

of sequential, overlapping or total CHANNEL steps such that the entire CHANNEL is calibrated.

]

CHANNEL CHECK A CHANNEL CHECK shall be the qualitative assessment of CHANNEL behavior during operation by observation. This determination shallinclude, where possible, comparison of the CHANNEL indication and/or status with other indications and/or status derived from independent instrument CHANNEL (s) measuring the same parameter.

Fuel assemblies shall be limited to those fuel designs that have been analyzed with applicable NRC staff approved codes and methods, and shown by tests j

or analyses to comply with all fuel safety design bases. A limited number of lead test i

assemblies that have not completed representative testing may be placed in non-limiting core regions.
