During GASEOUS RAOWASTE SYSTEM operation.

During waste gas release.

During MODES 1, 2, 3 or 4 or with irradiated fuel in the fuel storage pool.

NIP Functional test should consist of, but not be limited to, a verification of system isolation capability by the insertion of a simulated alarm condition.

The CHANNEL FUNCTIONAL TEST shall also demonstr ate that automatic isolation

(2) The CHANNEL FUNCTIONAL TEST shall also demonstrate that control room alarm annunciation .occurs if any of the following conditions exists:

1. Instrument indicates measured levels above the alarm setpoint.
2. Circuit failure.
3. Instrument indicates a downscale failure.
4. Instrument controls not set in operate mode.

(3) The initial CHANNEL CALIBRATION shall be performed using one or more of the reference standards certified by the National Bureau of Standards (NBS) or using standards that have been obtained from suppliers that participate in measurement assurance activities with NBS. These standards shall permit calibrating the system over its intended range of energy and measurement range. For subsequent CHANNEL CALIBRATIOH, sources that have been related to the initial calibration shall be used.

(4) The CHANNEL CALIBRATION shall include the use of standard gas samples containing a nominal:

1. One volume percent oxygen, balance nitrogen, and
2. Four volume percent oxygen, balance nitrogen.

The channel check for channels in standby shall consist of verification that the channel is "on-line and reachable."
