Miyahara, Kaname  ; Kato, Tomoko 

Japan Atomic Energy Agency (JAEA) rigorously continues to conduct research and development for establishing scientific and technical basis as an advanced knowledge base for implementation and safety regulations of HLW geological disposal. The current main goal of the regulator is to establish the required structure of safety goals and guidelines. In this respect, knowledge is required to provide a guidance to support definition of regulatory guidelines and guidance on demonstration of compliance. These may involve international review of regulations in particular with regard to areas where there is a lack of consensus (e.g. cut-off times, performance measures in the distant future). This report is to provide an example of an international review of key issues for regulations on geological disposal.
