What is the response of the Containment Atmosphere Control System when a valid high charcoal temperature alarm is actuated? A. The affected unit fan stops, reducing air flow across the charcoal filters.B. When air stream temperature reaches 300 degrees, the affected unit fan stops.C. The outlet damper throttles air flow reducing the reaction rate in the charcoal bed to maintain temperature below 2000F.D. Automatic fire protection will initiate to cool the charcoal bed.
