Sampling device with tritiated water sampling bottle and tritiated water sampler

Abstract

The invention discloses a sampling device with a tritiated water sampling bottle and a tritiated water sampler. The tritiated water sampling bottle comprises a shell and a pluggable inner container, asealing ring is arranged between the shell and the inner container, a sealed gap cavity is defined between the shell and the inner container, an upper gas connector and a lower gas connector are arranged on the shell, the upper gas connector is communicated with the gap cavity, the inner container comprises an inner container containing cavity, a flow guide supporting cover is arranged on the lower portion of the inner container containing cavity, gas holes are formed in the side wall of the inner container, the gap cavity is communicated with the inner container containing cavity through thegas holes, and the inner container containing cavity is communicated with the lower gas connector of the shell. The sampling device is smooth to operate, and samples are conveniently and rapidly replaced by the pluggable inner container. After the pluggable inner container is inserted into a sampling bottle body, the sealing performance of a bottle cavity is ensured by the sealing ring, gas leakage is avoided, and tritiated water sampling efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of radiation protection, and relates to a sampling of radioactive gas, in particular to a sampling device for a tritiated water sampling bottle and a tritiated water sampler. Background technique [0002] Tritium is an important radioactive gas nuclide emitted by the fission power operation reactor. The tritium leaked into the surrounding environment by various nuclear facilities will lead to an increase in the tritium activity of the surrounding atmosphere, and the staff working in the reactor building and related auxiliary buildings of the nuclear power plant will Tritium is ingested through various routes, resulting in a certain degree of internal exposure. Therefore, it is necessary to sample and detect tritium in the surrounding environment. [0003] Tritiated water sampling methods usually include: bubbling method, condensation method, desiccant adsorption method and freezing method. In the tradition...
