ACTION 136 With the number of channels OPERABLE less than required by the
-'inimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided the flow rate for the inoperable channel(s) is estimated at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
ACTION 137 - With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, operation of the offgas system may continue provided grab samples are collected at least once per 4
hours and analyzed within the following 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
ACTION 138 - With the number of channels OPERABLE less than required by the Hinimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided samples are continuously collected starting within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of discovery, using auxiliary sampling equipment as required in Table 4.11.2-1.
ACTION 139 a.
With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided grab samples are taken at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and these samples are analyzed for gross activity within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for a radioactivity limit of detection of at least 1

During offgas system operation.
Includes high range noble gas monitoring capability.
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, or using actual samples of gaseous effluents that have been analyzed on a system that has been calibrated with NBS traceable sources.
These standards shall permit calibrating the system over its intended range of energy and measurement.
For subsequent CHANNEL CAi IBRATION, sources that have been related to the initial calibration may be used.
The CHANNEL FUNCTIONAL TEST shall also demonstrate the automatic isolation capability of this pathway and that control room alarm annunciation occurs if the instrument indicates measured levels above the Alarm/Trip Setpoint (Each channel will be tested independently so as to not initiate isolation during operation).
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.
The CHANNEL CALIBRATION shall include the use of standard gas sample;-
containing a nominal:
(1)
One volume percent
- hydrogen, balance
- nitrogen, and (2)
Four volume percent
The CHANNEL CALIBRATION shall also demonstrate that automatic isolation of this pathway occurs when the instrument channels indicate measured levels above the Trip Setpoint.
