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 January 1994 to March 1995. Appendices present comprehensive information, such as monitoring program, monitoring results, meteorological data and annual discharges from the plant.

This manual includes the standard procedures for analysis of radioactive materials and chemical polluants in liquid and gaseous waste elluent discharged into the environment from the nuclear facilities of Tokai Works of PNC. The third edition, PNC N852-84-06 was published in 1984. Almost all analytical procedures have been modified and new technique has been used for nine years, so the forth edition revised entirely was to be published this time. And most of analytical procedures will be revised with the point of improving of reliabiliy.

Dose rates on the surface of the primary cooling system (i.e. pipes, pumps, and heat exchangers) in JOYO have been on the increase by long-term accumulation of RADIOACTIVE CORROSION PRODUCT:CP. Therfore, dose rates in the primary loop cell are also increasing. So it is necessary to pay attention to exposure doses of workers in this area. We have been measuring dose rates in order to evaluate radiation build-up around this area since 1978 Consequently, we estimated of following. (1)Dose rates on the surface of primary cooling system (pipes) at full power operation (100MWt) are estimated at 8.4 
10
R/h from the decay curve after the reactor shut down. (2)It might be possible for workers to enter primary coolant cell six days after the reactor shut down. (3)Radiation levels on the surface of the pipes during maintenance period estimate to 48 mR/h at 4 EFPY from the initial reactor operation.
