Based on the regulations (the safety regulation of Tokai Reprocessing Plant, the safety regulation of nuclear fuel material usage facilities, the radiation safety rule, the regulation about prevention from radiation hazards due to radioisotopes, which are related with the nuclear regulatory acts, the local agreement concerning with safety and environment conservation around nuclear facilities, the water pollution control law, and by law of Ibaraki Prefecture), the effluent control of liquid waste discharged from the Nuclear Fuel Cycle Engineering Laboratories of Japan Atomic Energy Agency has been performed. This report describes the effluent control results of the liquid waste in the fiscal year 2018. In this period, the concentrations and the quantities of the radioactivity in liquid waste discharged from the reprocessing plant, the plutonium fuel fabrication facilities, and the other nuclear fuel material usage facilities were much lower than the limits authorized by the above regulations.

The Hydrazine has been used for water treatment of the boiler in general industry scene. It has been used in NCL from 1995, too. Ministry of Health, Labour and Welfare do announcement about using hydrazine in 2006, and NCL began to try operation without hydrazine. Hydrazine was replaced to the other reagent that was selected based on the result of a research and an evaluation. Therefore safeguard of environment and labour was carried on by new operation method of water treatment from 2010. This report was described about the result of research and development.

Tokai Utility Center (TUC) is the facility that products and feeds steam for Tokai Reprocessing Plant (TRP), Plutonium Fuel Production Facility (PFPF), etc. The boiler system needs the management based on the law of "Industrial safety and Health Act" and "Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors". In this situation, activity of preservation of environment and energy-save are carried out by means of the improvement of steam generation process and the change of additive to water. Quality assurance procedure has been applied in order to improve the boiler operation continuously. This report describes about various activities of the management, the environment, the energy-saving, and a future action.
