Technical Specification Page Definition 1.4 1-1 The following Technical Specifications for Facility Operating License No. DPR-75 are affected by this change request:

Technical Specification Page Definition 1.4 1-1 Insert "A" A CHANNEL CALIBRATION shall be the adjustment, as necessary, of the channel output such that it responds within the necessary range and accuracy to known values of the parameter that the channel monitors. The CHANNEL CALIBRATION shall encompass the entire channel, including the required sensor, alarm, display, and trip functions, and shall include the CHANNEL FUNCTIONAL TEST. Calibration of instrument channels with resistance temperature detector (RTD) or thermocouple sensors may consist of an inplace qualitative assessment of sensor behavior and normal calibration of the remaining _agjustable devices in the chagn~l.

Whenever an RTD or thermocouple sensing element is replaced, the next required CHANNEL CALIBRATION shall include an inplace cross calibration that compares the other sensin _elements with the recently installed sensin _eleme~t. The CHANNEL CALIBRATION may

( ~~ performe y means of any series of sequential, overlapping,

"'---r total channel steps so that the entire channel is calibrated.

1.0 DEFINITIONS .

DEFINED TERMS l.l The DEFINED TERMS of this section appear in capitalized type and are appli~able throughout these Technical Specifications.

ACTION 1.2 ACTION shall be that part of a specification which prescribes remedial measures required under designated c.onditions.

AXIAL FLUX DIFFERENCE 1.3 AXIAL FLUX. DIFFERENCE shall be the difference in normalized flux signals between the top and bottom halves of a two section excore neutron detector.

CHANNEL CALIBRATION 1.4 A CHANNEL CALIBRATION shall be the adjustment,. as necessary, of the c annel output such that it responds with the necessary range and accuracy to known values of the parameter which the channel *monitors. The CHANNEL CALIBRATION shall *encompass the entire channel including the sensor and al arm and/or trip functions, and shall include the"CHANNEL FUNCTIONAL TEST. The CHANNEL CALIBRATION may be performed by-any series of sequential, overlapping or

.total channel steps such that the entire channel is calibrated.

CHANNEL CHECK 1.5 A CHANNEL CHECK shall be the qualitative assessment of channel behavior during operation by observation. This determination shall include, where possible, comparison of the channel indication and/or status with other indications and/or status derived from independent instrument channels measuring the same parameter.

CHANNEL FUNCTIONAL TEST 1.6 A CHANNEL FUNCTIONAL TEST shall be the injection of a simulated signal into the channel as close to the primary sensor as practica~le to verify OPERABILITY including alann and/or trip functions.
