FIELD: power industry.
SUBSTANCE: device includes active filtration system containing inlet and outlet connection pipes, electric fan and filter, and passive filtration system including output channels, heat exchange channels and exhaust tube. Ejector is installed between passive filtration system and exhaust tube, and inter-cover space is equipped with pre-filter. Ejected gas nozzle is connected to outlet connection pipe of passive filtration system, ejecting gas nozzle is connected to gas holder or other capacity with compressed gas or air, and outlet nozzle is connected to exhaust tube. At that, output channels are arranged in inter-cover space and connected to inlet connection pipe of pre-filter, and heat exchange channels are built in output channels.
EFFECT: increasing NPS safety by preventing emergency emissions of radioactive steam-gas mixture at accidents.
