Embodiment Construction

[0019] In order to make the purpose, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0020] see figure 2 As shown, the nuclear power plant radioactive waste liquid treatment system of the present invention includes a chemical drainage storage unit 10, a process drainage storage unit 20 and a surface drainage storage unit 30, and the three units respectively store chemical drainage, process drainage and surface drainage.

[0021] There are two connection paths between the chemical drainage storage unit 10 and the monitoring tank 40: the first one is directly connected to the monitoring tank 40 through the filter 12 and the evapora...

Abstract

The invention discloses a nuclear power station radioactive waste liquid treatment system which comprises a chemical discharged water storage unit, a process discharged water storage unit and a ground discharged water storage unit. The chemical discharged water storage unit is connected to a monitoring tank through a first filter and an evaporation unit, the process discharged water storage unit is connected to the monitoring tank through a second filter, a first desalting bed, a second desalting bed and a third filter, the monitoring tank is connected to a nuclear island waste liquid discharge system, and the nuclear power station radioactive waste liquid treatment system further comprises a third desalting bed and a fourth filter which are arranged on a pipeline between the chemical discharged water storage unit and the monitoring tank. Compared with an existing system, the nuclear power station radioactive waste liquid treatment system has the advantages that one desalting bed and one filter are added, and chemical discharged water and process discharged water can be subjected to further precision treatment selectively, so that system operational flexibility is improved while discharged waste liquid is guaranteed to meet requirements of current national standard coastal site treatment limits, and influences on public due to the fact that radioactive substances flow to the environment are reduced.

Description

technical field [0001] The invention relates to the treatment of radioactive waste liquid of nuclear power plants, and more specifically, the invention relates to a radioactive waste liquid treatment system of a pressurized water reactor nuclear power plant. Background technique [0002] The nuclear power plant radioactive waste treatment system (TEU) is used to receive, store, monitor and treat the radioactive waste produced by the nuclear power plant. Currently, two units generally share one system. The system classifies and collects the waste liquid according to the radioactivity concentration and chemical substance content of the waste liquid, and treats them separately. The specific methods are as follows: a) For the process drainage with low chemical impurity content, the desalination process is generally used, and evaporation can also be used. , Filtration process; b) For chemical drainage with high chemical impurity content and high radioactive concentration, evapora...
