Skyshine dose calculation code system SKYOSD for operational scenario of radioactive waste disposal

Watanabe, Masatoshi; Takeda, Seiji ; Kimura, Hideo

The shyshine dose to the public at the site boundary of radioactive waste disposal facility has been calculated for the operational scenario which is one of the scenarios for assessing the radionuclide concentration limits for low-level radioactive wastes. The skyshine dose was calculated with the point kernel method in the previous assessment. A computer code system, SKYOSD, employs more rigorous transport equation than before. The SKYOSD stores a one-dimensional transport calculation code ANISN-JR to calculate photon fluence rate on the disposal facility, and a two-dimensional transport calculation code DOT3.5 to calculate dose from a point kernel predetermined on the facility. This report provides a description for the structure of the SKYOSD code system and the parameter setting for skyshine dose calculation.
