Description

technical field [0001] The invention belongs to the technical field of nuclear power plants, and in particular relates to a water sealing device for a radioactive waste gas treatment system of a nuclear power plant. Background technique [0002] Each unit of a nuclear power plant is equipped with a radioactive waste gas treatment system, which is used for the removal of radionuclides to achieve discharge to the environment. [0003] During the operation of the unit, due to the high humidity of the radioactive waste gas treatment system, a condenser is installed in the system to condense the moisture in the system, and the condensed water is continuously discharged through the condensed water discharge pipe of the condenser. If the condensed water is discharged directly, the radioactive waste gas treatment system will not be able to form a closed system, the operating flow rate will not meet the design requirements, and the system cannot be put into operation. [0004] In or...
