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 April 1996 to March 1997. Dose estimation includes unplanned discharges during fire and explosion at the Bituminization Facility of the TRP on March 11th. Appendices present comprehensive information, such as monitoring program, monitoring results, meteorological data and annual discharges from the plant.

A tool for meshing sphere arrangements was programmed in order to perform finite element calculations. Sphere arrangements are investigated in frame of the feasibility study of the sphere-pac nuclear fuel. One major concern of this study is the thermal conductivity of the arrangement. Further concerns are the mechanical behavior and sintering of the fuel. The thermal conductivity of the fuel was addressed with the computer code SPACON based on a unit cell approach and a radial heat flow experiment. However, a further approach using the finite element method is desirable, in order to better understanding the thermal flow through the package and to cross check with SPACON data and with experimental data. Also the mechanical behavior of the fuel could be addressed using the finite element technique.

The meteorological observation has been performed since 1955 in PNC Tokai-works. After 1974, this observation came to measure on the top of the meteorological tower (100m above sea level) for the environmental assessment of a radioactive waste with the atmospheric discharge from the reprocessing plant. This report presents an atmospheric phenomenon statistic result and an examination about a characteristic of the atmosphere diffusion based on the data from 1977 to 1995. Characteristics of the result are as follows; (1)It was confirmed that the maximum air concentration point that was calculated based on the discharge amount from reprocessing plant and atmospheric phenomenon statistic of each year appears at near point in the safety assessment of 1977. (2)In some case, a maximum concentration point has appeared at about 800m in the west-southwest direction owing to the deference of appearance frequency of the atmospheric stability, etc. Normally it appears at about 2,000m point in south-west direction. Still, as reference materials, atmospheric phenomenon statistics result and relative concentration were mentioned.
