Abstract

The invention belongs to the technical field of tritium adsorption performance experiments, and particularly relates to a tritium gas adsorption performance experiment device and a tritium gas adsorption performance experiment method, which are used for measuring the tritium gas adsorption performance of a sample to be measured. The device comprise a test box (1), wherein the interior of the testbox (1) is provided with a closed space and the body of the test box (1) is provide with a plurality of interfaces; The device also comprises a dry air input device (2), a standard tritium gas input device (3), a vacuum pump (4), a circulating pump (5), an ionization chamber (6), a first ethylene glycol bubbler (7), a hygrothermograph (9) and a pressure gauge (10) which are detachably arranged onthe test box (1) through the interfaces. According to the invention, a sample tritium adsorption device and a measuring device are integrated into a whole, so adsorption of a to-be-measured sample totritium is balanced in the closed test box (1), balanced gas in the test box (1) is directly measured, experimental steps are simplified, manual repeated operation is reduced, adsorption and desorption are simultaneously carried out in a closed space in the test box (1), so the method is more scientific.

Description

technical field [0001] The invention belongs to the technical field of tritium adsorption performance experiment, and in particular relates to a tritium gas adsorption performance experimental device and a method thereof. Background technique [0002] Tritium (3H or T) has important applications in fusion energy, tritium targets, tritium lamps, and radioactive tracers. Although the radioactive toxicity of tritium is low, tritium (tritium gas, tritium water) has a strong penetrating ability, and it is easy to seep out of the containing material, and even penetrate into the human body to cause harm. Using suitable anti-tritium penetration materials, such as metal materials, inorganic non-metallic materials and organic polymer materials, is an essential anti-tritium measure to block tritium in a certain space. It is also an important measure to decontaminate tritium by using suitable tritium adsorption materials to adsorb tritium compounds on the decontamination surface and im...
