TABLE 4.15.8 NOTAT3ONS l
a.
Instrumentation shall be OPERABLE and in service except that a channel may be taken out of service for the purpose of a check, calibration, test or maintenance without declaring it to be inoperable.
b.
During releases via this pathway, c.
During main condenser offgas treatment system operation.
d.-
During operation of the condenser air ejector.
e.
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. Instrument indicates a downscale failure.
- 3. Instrument controle not set in operate mode.
- 4. Instrument electrical power loss.
f.
The CHANNEL CALIBRATION shall be performed according to established station calibration procedures.
g.
A CHANNEL CALIBRATION shall include the use of at least two standard gas i
samples, each containing a known volume percent hydrogen in the range of the instrument, balance nitrogen.
.h.
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. Instrument indicates a low countrate/ monitor failure.
- 3. Switch cover alarm shall be verified to alarm when the cover is opened; and clear when the cover is closed after the faceplate switches are verified in their correct positions.
- i. 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. Instrument indicates a low countrate/ monitor failure.
