Abstract

The invention discloses a multi-concentration tritiated water vapor generating device which comprises a bubbler containing standard tritiated water, a cold hydrazine, a temperature regulator and a thermometer, an air inlet pipe is installed at the input end of the bubbler, and an inlet valve, a diaphragm pump, a dryer, a filter, a flow control valve, a flow meter and a valve are sequentially installed on the air inlet pipe. An air outlet pipe is mounted at the output end of the bubbler, one end of the air outlet pipe extends into the upper layer in the bubbler and is communicated with air in the upper layer in the bubbler, and an outlet valve is mounted on the air outlet pipe. According to the invention, the temperature of standard tritiated water for bubbling can be changed through the temperature regulator and the cold hydrazine without disassembly, so that the isotope fractionation coefficient and the saturated water content are further changed, the generation of standard tritiated water with different concentrations is finally realized, the complexity of the tritiated water operation link and the field calibration process by personnel is greatly reduced, and the production efficiency is improved. And the exposure risk of tritium water to operators is greatly reduced, so that the radiation safety of field calibration workers is enhanced.

Description

technical field [0001] The invention belongs to the technical field of multi-concentration tritiated water vapor generation, in particular to a multi-concentration tritiated water vapor generation device. Background technique [0002] In the nuclear energy industry and national defense industry, tritium is an extremely important and special nuclear material, which can not only cause internal radiation damage to the human body, but also contaminate instruments and equipment in tritium-related sites. Therefore, the monitoring of tritium has become a tritium-related operation site. An important part of routine radioactivity monitoring. In order to meet the requirements for measurement and calibration of tritium monitoring instruments in national regulations and ensure the correctness of monitoring results, for environmental radioactivity in some special nuclear-related sites, on-site calibration work can be carried out without the tritium monitoring instrument being offline. A...
