FIELD: nuclear technologies; environmental protection.
SUBSTANCE: nuclear installation (1) contains containment (2) with pressure relief pipeline (6) connected, into which Venturi scrubber (12) located in tank (14) with washing liquid (W), and throttling device (24) are connected successively. Venturi scrubber (12) and throttling device (24) provide for their installation in Venturi scrubber (12) in case of critical expansion of the vapour/air mixture in pressure relief pipeline (6), at throttling device (24), at a vapour/air mixture flow velocity of over 150 m/s, predominantly over 200m/s.
EFFECT: highly reliable elimination of possibility of emissions of even smallest radioactive substances to environment.
