40 CFR 191, Subpart A, 4 and 40 CFR 61, Subpart H. 5 These regulations place stringent requirements on
the allowable annual dose equivalent to any member of the public. The sampling period and sample
volume are maximized to provide a reasonable lower limit of detection.
7.1.4.4 Underground Monitoring Systems
The underground air monitoring system utilizes continuous air monitors (CAMs) to indicate airborne
radioactivity levels in the air from the active waste disposal rooms. In case of increases in the airborne
radioactivity, an alarm occurs and exhaust flow is shifted through HEPA filtration prior to release the
environment.
The effluent monitoring systems are designed and environmentally qualified to withstand the effects of
the Design Basis Earthquake, and are installed with backup power to allow monitoring in the event of a
power failure.
