Summary

Prototype Fast Breeder Reactor (PFBR) is a pool type, sodium cooled, 500 MWe nuclear reactor presently under construction at Kapakkam. The air conditioning and ventilation ( ACV) system for PFBR is designed to minimize the occupational and public dose of radiation. The system maintains airflow from less radioactive to more radioactive zones. To avoid the spread of contamination, radioactive exhaust air is filtered before releasing to the atmosphere through a stack. The system incorporates features for isolation of containment in case of accidental release of radioactivity. It also provides necessary air changes based on radioactivity, contamination and O2 deficiency, or Annual Limit on Intake (ALI) and Derived Air Concentration (DAC). It maintains negative or positive pressure with respect to outside atmosphere in various buildings based on the requirement of radioactivity containment or ingress control outside air. The Acv system is also designed to contain fire.
