Due to scarce global energy, in order to respond to energy conservation, environmental protection and emission reduction, all countries in the world accelerate the development of nuclear energy, and China also develops clean power vigorously, in which nuclear power is the main direction of power structure adjustment in the future and the scale of investment will greatly exceed the conventional power plant. The national strategy for nuclear power development changes from “moderate development to positive development”. Under this background, China's nuclear energy will get a good opportunity for development. With the development of nuclear power, more and more new technologies are applied in the field of nuclear power.
At present, the membrane separation technology has not only been maturely used in water treatment of nuclear power conventional island, but also gradually has begun to use the radiochemical related treatment field.
In the process of operating pressurized water reactor power plant, the impurity concentration in the first loop of boric acid will increase year by year, and the pollution can’t be fully removed by using the available processing technology. With the development of time, the accumulation of pollutants results in the increase of hidden troubles in nuclear power plants, and membrane separation and purification system can effectively assists the purification system of the existing nuclear power plants to reduce the hidden troubles in nuclear power plants.
High-precision special separation elements can be used for separating radioactive materials, removing and concentrating radioactive waste water, such as boron water purification of primary system, removal of dissolved silicon and concentration of radioactive wastewater.
