FIELD: physics.
SUBSTANCE: apparatus for cleaning a radioactive steam-gas mixture during accidental discharge of a pressurised water reactor has a protective casing having safety valves, connected by a conduit pipe to series-arranged louvre separator and steam-jet ejector, located outside the protective casing. The separator is connected to an accumulator tank in the top part and to a container for collecting separated liquid in the lower part. The ejector is placed in a pond having perforated pipes around its periphery. The accumulator tank and the perforated pipes are connected by receivers. The pond is equipped with an air cooler and an exhaust hood over it. The exhaust hood is connected to a gas holding pipe which is fitted with aerosol filters. The gas holding pipe is connected by gas-relief lines to the separator and the conduit pipe. The accumulator tank and the pond are filled with an alkaline solution.
EFFECT: ensuring radiation safety and explosion safety during emergency triggering of safety valves of a pressurised water reactor owing to removal of the steam-gas mixture from the primary containment of the reactor.
