An Environmental Impact Assessment for Sea Transport of High Level Radioactive Waste

Abstract

This work was carried out to study the safety evaluation in a hypothetical submergence accident onto the seabed, prior to the international maritime transpott between Europe and Japan in 1995. In this study, inadmissibly conservative assumptions were omitted in order to construct adequate accident scenarios from the engineering aspect. Input data of source terms of high level vitrified wastes, various flow coefficienss in the sea, and other factors were thoroughyy examined and, finally, a new concept of a solution method for radioactive nuclides concentration was proposed with regard to oceanography.
