Abstract: M310 reactor units are the earliest Nuclear Power Units introduced in China. Although their radioactive wastewater treatment systems are operating stably, they face challenges such as high operating costs, unstable efficiency, low decontamination factors, and high solid waste output, etc. In particular the low decontamination factors, current processes and equipment are no longer able to meet the demand for further reducing the total amount of radioactive nuclides emitted into the environment. There is still a considerable gap compared to advanced countries and regions. This paper summarizes the current operational status and considers the mature and advanced wastewater treatment technologies at home and abroad, with the aim to elaborate the optimization direction and suggestions for the radioactive wastewater treatment system of M310 Nuclear Power Units.

Key words: M310 reactor unit, nuclear power, radioactive wastewater, decontamination factors
