FIELD: ventilation.
SUBSTANCE: invention relates to nuclear reactor primary protective shell ventilation systems. Wet filter uses inclined manifold, having plurality of outputs, which are connected through first set of filters with metal fibers, submerged into water basin, located inside housing under pressure. Above water basin mist separator for removal of any fog is suspended, carried along in filtered flow prior to passage through second stage of high-density dry filters with metal fibers, connected to second manifold, which is connected to output on housing under pressure. Vessel under pressure is connected to exhaust passage into atmosphere.
EFFECT: technical result is reducing risk of radioactive emission to atmosphere.
