Embodiment Construction

[0074] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0075] Principle brief introduction of the present invention:

[0076] A1: In the actual production process, the radioactive raw material liquid is injected into the degassing tower for degassing. After the radioactive raw material liquid is degassed by the degassing tower, the degassing tower will discharge the radioactive effluent. The ratio of the radioactivity of the radioactive raw material liquid to the radioactivity of the radioactive effluent is the degassing factor of the degassing tower.

[0077] A2: Generally, it is easy to measure the radioactivity of the radioactive raw material liquid, and it can be considered that the radioactive activity of the radioactive raw material liquid is a known data; more diffi...

Abstract

The invention discloses a method and device for test detection of degassing factors of a degassing tower of a nuclear power plant. The method for test detection of the degassing factors of the degassing tower of the nuclear power plant comprises the following steps of S1, dissolving simulation gases in simulation material liquid to simulate radioactive raw material liquid, wherein the simulation material liquid is a solution which contains boric acid in a dissolved mode, the simulation gases comprise N2, O2 and a stable isotope Xe, and the Xe is a tracer element; (2) injecting the simulation material liquid with the simulation gases in a dissolved mode into the degassing tower to carry out degassing; (3) using the simulation material liquid discharged from the degassing tower after the degassing as tower bottom material liquid, measuring the concentration of the Xe in the tower bottom material liquid, and calculating the degassing factors of the degassing tower. The device for test detection of the degassing factors of the degassing tower of the nuclear power plant comprises a mass spectrometer, a feed liquid tank, a gas-liquid mixer, the degassing tower and a sampler, wherein the feed liquid tank, the gas-liquid mixer, the degassing tower and the sampler are connected in sequence. The method and device for test detection of the degassing factors of the degassing tower of the nuclear power plant have the advantages of being good in economy of detection of the degassing factors of the degassing tower, free of radioactive hazards, and capable of protecting the environment.

Description

technical field [0001] The invention relates to a degassing tower, and more specifically relates to a test and detection method and device for testing and detecting the degassing factor of a degassing tower of a nuclear power plant. Background technique [0002] The boric acid recovery system of the nuclear power plant is mainly used to treat the reusable boric acid waste liquid, which comes from the reusable primary circuit coolant of the discharge pipeline of the chemical capacity system of the nuclear power plant, the exhaust of the nuclear island and the drainage system. [0003] The boric acid recovery system of nuclear power plant treats the process of reusable boric acid waste liquid, including purification (filtration and desalination), degassing and boron-water separation, in which the degassing process is completed by the degassing tower of the nuclear power plant. The main function of the degassing tower in nuclear power plants is to remove hydrogen, nitrogen and ...
