【Abstract】 A prototype delay unit of radioactive noble gas with process flow was established and some experiments simulating different airflow parameters of nuclear power plants were carried out. Experimental results of performance testing show that the gas cooler meets dehumidification requirements. The silica gel bed can dry gas flow to the required level of relative humidity. And the activated carbon delay bed has good retention capability for noble gas. Therefore the designed prototype delay unit for radioactive noble gas is applicable for nuclear power plants.更多还原
