1.6 Instrument Channel Test Instrument channel test means injection of a simulated signal into the channel to verify its proper response including, where applicable, alarm and/or trip initiating action.

1.7 Instrument Channel Calibration Instrument channel calibration means adjustment of channel output such that it responds, with acceptable range and accuracy, to known values of the parameter which the channel measures. Calibration shall encompass the entire channel, including equipment actuation, alarm, or trip. 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 adjustable devices in the channel. The channel calibration may be performed by means of any series of sequential, overlapping, or total channel steps.

1.8 Major Refueling Outage For the purpose of designating frequency of testing and surveillance, a major refueling outage shall mean a regularly scheduled refueling outage; however, where such outages occur within 8 months of the end of the previous refueling outage, the test or surveillance need not be performed until the next regularly scheduled outage.

1.9 Oierating Cycle An operating cycle is that portion of Station operation between reactor startups following each major refueling outage.

1.10 Test Intervals The test intervals specified are only valid during periods of power operation and do not apply in the event of extended Station shutdown.

1.11 Primary Containment Intearity Primary containment integrity means that the drywell and absorption chamber are closed and all of the following conditions are satisfied:

a. All non-automatic primary containment isolation valves which are not required to be open for plant operation are closed.

b. At least one door in the airlock is closed and sealed.
