PRESSURE RELEASING METHOD FOR ATOMIC POWER STATION, PRESSURE RELEASING SYSTEM FOR ATOMIC POWER STATION AND RESPECTIVE ATOMIC POWER STATION

摘要

FIELD: atomic physics.;SUBSTANCE: invention relates to a method and a device for releasing pressure of an atomic power station (2), having a protective casing (4) for holding radioactive carriers and an outlet (10, 10') for the discharge stream. The stream is directed using a discharge pipe (12, 12'), fitted with a filter system, from the protective casing (4) into the atmosphere. The filter system comprises a filter chamber (16) with a sorption filter (18). The discharge stream is first directed into a high-pressure portion (70) then undergoes pressure reduction in a throttling device (72), then at least partially directed through the filter chamber (16) with a sorption filter (18) and then finally released into the atmosphere. The discharge stream, in which pressure is reduced using the throttling device (72), is directed through an overheating portion (80) on the high-pressure portion (70) immediately before entering the filter chamber (16).;EFFECT: effective retention of radioactive carriers contained in the discharge stream, particularly iodine-containing organic compounds.;36 cl, 5 dwg
