CONFINEMENT FILTRATION SYSTEMS GENERAL OVERVIEW e

THE CONFINEMENT FILTRATION SYSTEMS PROVIDE PRESSURE CONTROL AND RAD _I0 ACTIVE MATERIAL FILTRATION FOR THE:

REACTOR CONTAINMENT BUILDING (RCB) CONFINEMENT REACTOR SERVICE BUILDING (RSB) CONFINEMENT e

THE CONFINEMENT FILTRATION SYSTEMS ARE DESIGNED TO MAINTAIN

.25 IN. W.G. NEGATIVE PRESSURE IN THE DESIGNATED AREAS DURING:

NORMAL PLANT OPERATION RADI0 ACTIVE ACCIDENT CONDITION e

THE CONFINEMENT FILTRATION SYSTEMS ARE DESIGNED TO INCLUDE CAPACITY FOR RECIRCULATION.

THE RECIRCULATING OPERATING MODE IS UTILIZED DURING RADI0 ACTIVE ACCIDENT CONDITIONS 9
