System design is such that either the 1RM-VS-109 low range or high range noble gas monitor for each pathway will be in service. At a concentration of 1E-02 tICi/cc on the low range monitor, flow will normally swap to the high range monitor. The minimum and maximum instrument ranges listed are based on system software parameter limitations and pathway ODCM release flow rate. In addition, the maximum range is based on a release concentration of 1E-02 VICi/cc, limited by the automatic swap to the high range monitor.Note: Because actual pathway release flow rate may vary, the"Minimum Instrument Range" and "Maximum Instrument Range" may not reflect the actual instrument ranges. Site dose assessment corrects the pCi/s for source term and flow rate differences depending on selected default source term and decay period. IRM-1VS-109 monitors for low range noble gases at the discharge of the Auxiliary Building shielded area exhaust fans and at the discharge of the Containment Refueling Purge and Exhaust fan (during refueling).
