The Risk Technical Committee of the Atomic Energy Society of Japan has been published many Standards for procedures of probabilistic risk assessment of nuclear power plants. Following these activities, it has been started to provide a new standard for risk assessment of nuclear fuel cycle facilities. The scope of new standard include internal events and seismic events as an external events. The basis of standard is concept of "Graded Approach", the different level of details in assessment can be selected depended on the risk level of an each event at an each facility.

Efforts of developing methodologies and basic data for risk assessment are undertaken actively for NFFs in Japan. However, a systematic procedure for conducting risk assessment to achieve appropriate quality and reasonable cost that are commensurate with the risk of each facility has not been developed. Therefore, the Subcommittee on Risk Assessment of Nuclear Fuel Facilities newly organized under the Standard Committee, developed a new standard for systematic procedures for risk assessment of NFF s, which allows the users to select appropriate optional methods depending on the risk levels of their facilities.
