Description
technical field [0001] The invention relates to the technical field of radioactive inert gas treatment, in particular to a low-temperature activated carbon adsorption device for treating radioactive inert gas. Background technique [0002] The high-temperature gas-cooled reactor uses graphite as the moderator and helium as the coolant. It is an advanced nuclear reactor with inherent safety, high power generation efficiency, and extremely versatile uses. During normal operation of a nuclear power plant, radioactive noble gases (mainly krypton and xenon) will be produced due to the fission of atomic nuclei inside the reactor. It is difficult to collect radioactive inert gases by adsorption methods at or near normal temperature. In order to minimize the emission of radioactive inert gas, it must be collected by adsorption to reduce the radioactive hazards to the environment. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, ...
