Description

technical field

[0001] The invention relates to an iodine vapor sampling and measuring device, which is especially used in an environment where high-temperature water vapor exists, in particular an iodine vapor sampling and measuring device that can be used to measure the iodine removal efficiency of a containment filter discharge system. Background technique

[0002] A large amount of volatile fission products are produced during the operation of nuclear power plants. In the event of a severe accident, the integrity of the containment vessel is compromised, and fission gases will be released into the atmosphere, causing radioactive hazards to the environment. It can be seen that ensuring the integrity of the containment is the key to realizing nuclear safety, and the development of the containment filter and discharge system is particularly important. It can remove radioactive substances in the gas in the containment vessel, and depressurize the containment vessel through ...
