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.
