Abstract: Reuse of liquid effluents in inland nuclear power plants (NPPs) and discharge reduction of liquid effluents to environment is an effective way to protect water resources, and it is a necessary choice for inland NPPs to meet energy development plan and major safety requirements of site selection. The reusing feasibility of liquid effluent is studied based on design and operation experiences of NPPs. The results show that the recycling of treated laundry liquid in hot laundry and reusing of floor drains in reactor cavity and spent fuel pit cooling system are practicable, and can reduce the discharge of liquid effluents to environment by 8 400 m3 (Two units per year) accounting for the reduction of 51.8% of its total amount, and the reduced discharge of radioactivity in liquid effluents to environment by 4.8×105 Bq accounting for the reduction of 36.9% of its total radioisotope amount.

Key words: pressurized water reactor plant, liquid effluent, reuse, inland site
