Abstract

The invention discloses a radioactive nuclide collection device. The device comprises valves (1), a tank body (2), tank doors (3), filler boxes (4) and a radioactivity monitoring instrument (5), and can collect radioactive nuclides of radioactive sewage; a water inlet and a water outlet are formed in the upper end and the lower end of the tank body (2) respectively and are provided with the valves (1) to control the inflow and outflow of the sewage; furthermore, the radioactivity monitoring instrument (5) is arranged on the water outlet to detect the radioactivity of the outflow liquid; the filler boxes (4) are arranged in the tank body (2), and the sewage enters the tank body (2) and flows out after being purified by the filler boxes (4); the radioactive nuclide collection device is high in adsorption efficiency and wide in application range and brings convenience to adsorption material replacement.

Description

technical field [0001] The invention relates to a collection device, in particular to a radionuclide collection device. Background technique [0002] With the continuous development and application of nuclear energy, nuclear waste discharged from coastal nuclear power plants and marine nuclear power barrels, as well as nuclear leakage caused by nuclear accidents, will cause serious marine radioactive pollution, causing huge damage to the marine environment and even human society. Its impact can last hundreds of years or even thousands of years, or even longer. Therefore, it is necessary to treat seawater with a high degree of nuclear pollution, and it is also an important task to prevent and control marine nuclear pollution. [0003] Most of the existing radionuclide collection barrels only collect radioactive sewage without nuclide adsorption function, which not only has low utilization rate, but also takes up a large space; some collection barrels have adsorption function,...
