Upper and Lower Compartment Cooling Coils

Critical Reactor Vessel Compartment Cooling.
In pressurized water reactors (PWRs) that use ice condensers for rapidly absorbing thermal energy released to containment during a LOCA or MSLB, containment is divided into an upper and lower compartment. Separate coolers are used in each compartment during normal operation to maintain ambient temperature within acceptable limits.
