An airflow switch sensing high or low differential pressure across the fan actuates an alarm on the main control room control panel. A fan trip occurs when differential pressure across the fan exceeds the airflow switch setpoint (after a short time-delay; supply fan only). A trip of the supply fan for any reason causes a subsequent trip of the return and make-up fans.

Motor Trip A fan trip alarm actuates on the main control room control panel when the Local/Remote control switch is in Remote mode. A trip of the supply fan for any reason causes a subsequent trip of the return and make-up fans. A redundant ventilation train is available for operation as required.

Containment Charcoal Filter Unit Prefilter and HEPA Filters High Pressure drop across filter.

Differential p ressure switch sensing filter p ressure drop actuates an alarm on the local control panel.*

Containment Charcoal Filter Unit Charcoal Filters High leaving air temperature.

Temperature sensing devices sensing leaving air temperature actuate an alarm on the main control room control panel in the event of primary over-temperature condition. A secondary over-temperature condition actuates an alarm on the local control pa nel.* Local deluge valves are available for manual operation, as required.

An airflow switch sensing high or low differential pressure across the fan actuates an alarm on the local control pa nel.* A high differential pressur e also causes a fan trip.*

Motor Trip An auto-trip a larm actuates at the local control panel.* A trip of the supply fan for any reason results in a sub sequent trip of the return fan.

A trip of an operating return fan that results in operation of a supply fan in the absence of a return fan will cause U-1/2 Process Computer Room to main control room low pressure condition. The resulting low pressure condition subsequently actuates both lo cal and main control room c ontrol panel pressure alarms.

Supply Filters High pressure drop across filter.

Differential p ressure switch sensing filter p ressure drop actuates an alarm on the local control panel.*

Heating Coil Loss of instrument air signal to 3-way Flow Control Valve.

Heating coil goes to full heat).

Loss of station heat flow.

Low fan inlet te mperature is alarmed on the l ocal control panel when tem peratures fall below the alarm setpoint.* Low fan inlet temperature also results in a supply fan trip with alarms as desc ribed previously.

Steam Generator trip occurs.

Steam Generator trouble alarm actuates on the local control panel.*
