.3.7[(cont'd) 4.7 '(cont'd) 6 9.
Primary Containment Atmo:phara-Primary containment atmosphere shall be
- 9.. continuously monitored for hydrogen and
. Monitoring Instruments oxygen when containment integrity is Instrumentation shall be functionally required. The exception to this11s when a.
the Post-Accident Sampling System is to' tested and calibrated as specified in be operated.
In this instance, the Table 4.7-1.
containment atmosphere monitoring systems may be isolated for a period not to exceed 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> in a 24-hour period..The monitoring system shall be considered operable if at least one monitor is operable.
a) From and af ter the time the primary containment atmosphere monitoring e
instruments are found or made to be inoperable for.any reason, continued reactor operation is permissible'for the succeeding thirty (30) days unless one instrument monitoring each_ parameter is sooner made operable, provided an appropriate grab sample is obtained and analyzed at least 4
once each twenty-four (24) hour period.

'J? specification 3. 7. A.9.a cannot be met, 1.
Standby Gas Treatment System thi.' reactor shall be placed in the cold surveillance shall be performed as ut4Ltion within twenty-four (24) hours.
indicated below:
At least once per operating cycle, it B.
