Takeda, Seiji ; Watanabe, Masatoshi; Sawaguchi, Takuma ; Sasaki, Toshihisa; Ochiai, Toru; Kimura, Hideo

This document summaries the concept and method (scenario selection, model/code description and parameter selection) for estimation of the radioactivity concentration limits for trench disposal of transuranium and uranium wastes, and provide the derived values of the radioactivity concentration limit for each radionuclide in the wastes. The values for the transuranium waste are published in a Nuclear Safety Commission of Japan report.
