Abstract

The invention provides a gaseous tritiated water online detection system based on a plastic scintillator. By using the system, the activity of gaseous tritiated water can be measured in real time. According to the system, a pump is used for extracting a gaseous tritiated water sample from a sampling area and sending the gaseous tritiated water sample into a purification separator, the gas subjected to purification and separation is sent into a detection region, and the activity of tritiated water can be obtained in real time. The system comprises a sampling unit, a purification and separationunit, a measurement unit and a control unit. The gaseous tritiated water online detection system can measure gaseous tritiated water samples in various activities in real time, and has the advantagesof being short in measurement time and rapid in reaction. The problem about measuring tritium in real time is solved. The system further has the advantages of being easy to operate, capable of achieving software control and the like.

Description

technical field [0001] The gaseous tritiated water detection system based on plastic scintillator designed in the present invention particularly relates to an online detection system for gaseous tritiated water in a complex gaseous medium. Background technique [0002] During the operation of heavy water reactors and molten salt reactors, a large amount of tritiated water will be produced, and these tritiated water will enter the plant and other areas during the operation. Gases in these areas need to be measured before discharge to prevent emissions from exceeding national standards. The gas at these locations is complex and may also contain other types of radioactive material. The rays emitted by tritium have low energy and short range, and are easily interfered by other radioactive substances. The traditional tritiated water on-line monitoring system mostly adopts the method of bubbler collection, and then sends the collected water samples to liquid scintillation measur...
