JAEA-Review-2019-048.pdf:2.69MB

Environmental radiation monitoring around the Tokai Reprocessing Plant has been performed by the Nuclear Fuel Cycle Engineering Laboratories, based on "Safety Regulations for the Reprocessing Plant of Japan Atomic Energy Agency, Chapter IV - Environmental Monitoring". This annual report presents the results of the environmental monitoring and the dose estimation to the hypothetical inhabitant due to the radioactivity discharged from the plant to the atmosphere and the sea during April 2018 to March 2019. In this report, some data include the influence of the accidental release from the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co., Inc. (the trade name was changed to Tokyo Electric Power Company Holdings, Inc. on April 1, 2016) in March 2011. Appendices present comprehensive information, such as monitoring programs, monitoring methods, monitoring results and their trends, meteorological data and discharged radioactive wastes. In addition, the data which were influenced by the accidental release and exceeded the normal range of fluctuation in the monitoring, were evaluated.

This report summarizes outline, methods and measurement results of actual wastes of nondestructive measurement system using the passive $$gamma$$ method applied to the evaluation of the quantity of uranium in the drum waste (0.2 m$$^{3}$$) and container waste (1 m$$^{3}$$). The following are the results. (1) The measurement number of drum wastes was 18,884 (4,703 of the number were pit wastes), at the end of March, 2011. (2) The measurement number of container wastes was 749 (110 of the number were pit wastes), at the end of March, 2011. (3) About 60% of drum wastes and about 80% of container wastes were metal and concrete. (4) 75% of drum wastes were less than detection limit, and average of radioactivity is 3.4 Bq (U-238)/g. Then 17% of container wastes were less than detection limit, and average of radioactivity is 2.3 Bq (U-238)/g. (5) If clearance level is 1.0 Bq (U-238)/g (IAEA RS-G-1.7), about 80% of wastes are below the clearance level.
