ABSTRACT: Studies of the application of a variety of land disposal technologies to the storage and disposal of radioactive waste and soil have been carried out. It is feared that disposal of these materials at sea could result in marine diffusion and seismic and tsunami damage, but the advantages of sea disposal are its large capacity and isolation from the public. However, little research on sea disposal of radioactive waste and soil has been done. We studied the practicality of sea disposal technology as a way to dispose of radioactive waste and soil. For the study, we designed controlled substances sea disposal facilities with 2 Mm3 capacity and Level 2 earthquake resistance. We estimated both the cost of constructing the sea disposal facilities and the risk of exposure to radiation from the waste and soil in the facilities. The estimates were compared with the results of case studies of land disposal. The results showed that sea disposal meets necessary standards and ensures performance equivalent or superior to that of land disposal.
