ALARA and BAT concept in the design of radioactive waste disposal facilities

- A case study of Sweden -

Abstract

  Regulatory standards for intermediate-depth disposal in Japan will require facility design based on ALARA (As Low As Reasonably Achievable) and BAT (Best Available Technique). However, there are no examples of studies that show specific measures to meet the regulatory requirements for ALARA and BAT. On the other hand, there are some examples of facility design based on ALARA and BAT in radioactive waste disposal projects in other countries. In this paper, the Swedish approach is reviewed, and the methods of presenting ALARA and BAT are discussed to apply them to radioactive waste disposal projects in Japan.
