Problems solved by technology
The current solidification treatment methods such as cement solidification and vitrification can also be applied to the solidification treatment of boron-containing radioactive waste liquid. However, as mentioned above, borosilicate glass is tried to be used as a solidification agent in vitrification treatment. , Borosilicate glass also contains more boron elements, which makes it difficult for the quality of the final cured product to meet the expected standards

The embodiment of the invention provides a boron-containing radioactive waste liquid treatment method and system. The treatment method comprises the steps: acquiring the content of boron in the boron-containing radioactive waste liquid; preparing a curing agent which comprises boron, and determining the expected range of the content of the boron in the curing agent according to the content of the boron in the boron-containing radioactive waste liquid and the expected range of the content of the boron in a cured product; determining the formula of the curing agent based on the expected range of the content of the boron element in the curing agent, and preparing the curing agent according to the formula; mixing and heating the boron-containing radioactive waste liquid and the curing agent to form a molten substance; and cooling the molten substance to obtain the cured product. According to the treatment method and system provided by the embodiment of the invention, the quality of the cured product can be improved, and a relatively ideal treatment effect can be obtained.
Description
technical field [0001] The invention relates to the technical field of chemical treatment, in particular to a treatment method and system for boron-containing radioactive waste liquid. Background technique [0002] With the rapid development of the nuclear industry, how to deal with a large amount of radioactive waste generated in the nuclear industry is an urgent problem to be solved. Solidification treatment is a relatively safe and efficient method for radioactive waste treatment. [0003] Curing refers to selecting a solidifying matrix with high stability to contain these nuclides for a long time. Commonly used curing methods include glass curing, ceramic curing, glass ceramic curing, artificial rock curing, and various cement curing, etc. Among them, the vitrification technology is relatively mature, and the vitrification body has the advantages of low leaching rate and stable radiation, which makes the vitrification technology a hot spot in the research of curing techn...
