Environmental radiation monitoring around the Tokai Reprocessing Plant has been performed since 1975, based on "Safety Regulations for the Tokai Reprocessing Plant, Chapter VII - Environmental Monitoring". This annual report presents the results of the environmental monitoring and the dose estimation to the hypothetical inhabitants due to the radioactivity discharged from the plant during 1993. Appendices present comprehensive information, such as monitoring program, monitoring results, meteorological data and annual discharges from the plant.

Radioactive waste management research programs inevitably include laboratory solubili and sorption studies to provide data for radionuclide transport model. Estimation of lubility strongly depends on the reliability of thermodynamic data (e.g., carbonato-colexes) and may also depend on kinetic data on alteration of solubility limiting solid ases. Existing sorption data may include some kind of retardation mechanisms to be excded (e.g., precipitation). To develop these fundamental data, we must also consider a rge number of radioactive elements, a large number of factors (e.g., pH, Eh, complexinligands) in the repository environmentg, and numerous solid and aqueous species of radnuclides along with the many absorbents. Therefore, a systematic approach and researchlan are needed for obtaining and evaluation thermodynamic and sorption constants. The cus of this session was on thermodynamic data for aqueous species and solid phases imptant to the geological disposal system, on kinetic data

Nuclear energy is the second largest source of electric power in the United States. Tdate, nuclear power plants produced over twenty percent of the nation's electricity. Aof August 1991, there were 112 nuclear power reactors in the United States, and two mo were being built. By the year 2000, approximately 40,000 metric tons of nuclear wasteill be in temporary storage at reactor sites throughout the coutry. That amount is twi the amount that currently exists. In order to handle such waste, as well as the addedolume to be produced after the year 2000, the U. S. Department of Energt (DOE) is in t process of developing the waste management system that was authorized by the U. S Coness in 1987. The authorized system is illustrated in Figure 1. To summarize, spent nucar fuel from commercial power reactors will be accepted by the DOE at the reactor siteand transported to a monitored retrievable storage (MRS) facility for temporary storagand preparation for permanent disposal in a gelogic rep
