Description

AIST has been supporting scientific aspects of the Nuclear Regulatory Authority (NRA), mainly in regard to the regulation of site selection for radioactive waste disposal. NRA is constructing regulation criteria and examination guides for the disposal of intermediate-level radioactive waste (ILW) at intermediate depth prior to the geological disposal of high-level radioactive wastes (HLW). This paper introduces some examples of utilizing AIST’s R&D results for regulation of ILW disposal. This paper also presents examples of future tasks by analyzing the differences between the ILW and HLW disposal, and the differences between ILW regulation and criteria in the “Nationwide Map of Scientific Features for Geological Disposal” to categorize areas based on favorability for HLW disposal.
