Tritium measurement system and measurement method for pool reactor

Abstract

Embodiments of the present invention provide a tritium measurement system (100) for a pool reactor, comprising: an attenuation module (10) arranged to be connected to a coolant circuit of the pool reactor from which coolant is cooled The coolant circuit flows into the attenuation module (10), and the attenuation module (10) attenuates the coolant; a measurement module (11) is arranged to be connected with the attenuation module (10), and the attenuation module (10) The tritium activity of the attenuated coolant flowing out of the module (10) is measured; and a circulation module (12) is arranged to be connected to the measurement module (11), and the coolant after the measurement is discharged to the pool type in the coolant loop of the reactor. The tritium measurement system according to the embodiment of the present invention is beneficial to improve the tritium measurement accuracy, improve the environmental protection and safety of the measurement, reduce the cost of long-term measurement operation, and reduce the investment of personnel.

Description

technical field [0001] The invention relates to the technical field of radioactivity monitoring, in particular to a tritium measurement system and a measurement method for a pool reactor. Background technique [0002] Tritium is a radioactive isotope of hydrogen that has a wide range of applications in medicine, scientific research, industry, especially the nuclear industry (eg as the main lightweight material for nuclear fusion reactions). However, in the nuclear industry, low concentrations of tritium-containing waste gas and wastewater are released into the environment during tritium-related production activities. In addition to being directly ingested by humans through air and water, tritium in the environment can also be absorbed by plants and animals, and transmitted to humans through these animal and plant foods, thus endangering human health. Therefore, how to effectively monitor the radioactive level of tritium produced in the nuclear reaction process has become a ...

AI Technical Summary

Problems solved by technology

[0004] In the nuclear reactor coolant circuit, due to the existence of other high-activity radionuclides and the relatively low activity of tritium, if the radioactivity level of tritium from the coolant circuit is directly measured, it is easy to cause inaccurate measurement. Therefore, the application provides related measuring devices or methods to improve this problem
