Abstract

The invention provides a device for low-level radioactive wastewater MVC evaporation in a nuclear power plant. According to the invention, a steam recompressor fully enhances the taste of secondary steam for heating of an external heating natural-circulation heating chamber, so a fresh heat source is not needed to be replenished except that an external heat source is required for first starting; awaste liquid is adopted to exchange heat with condensed water, so a large amount of cooling water is no longer needed to fully condense secondary steam; and a secondary separator with higher efficiency is adopted, so radioactive decontamination factors can be further increased by 10 to 100 times .

Description

technical field [0001] The invention relates to the field of waste liquid treatment of nuclear power plants, in particular to an MVC evaporation process for low-level waste water of nuclear power plants and a device thereof. Background technique [0002] In the waste liquid treatment of nuclear power plants, the radioactive waste liquid with complex components and wide range of radioactive concentration changes is usually treated by evaporation and concentration. [0003] At present, my country's nuclear power plants and nuclear wastewater treatment and disposal plants mostly use two types of externally heated natural circulation evaporators and forced circulation evaporators, and there has been almost no improvement over the years. The natural circulation evaporator is prone to salting out and fouling in the heating tube, so that the frequency of equipment cleaning, maintenance and replacement of the heating tube is frequent; while the forced circulation evaporator uses a f...
