IEC/TR 63123 gives guidance for the application in the IAEA/IEC framework of the IEC 63147:2017/IEEE 497 corresponding to the adoption without modification of IEEE 497:2016. During their review of IEEE 497:2016, the experts of the review team noted that between the 2010 edition of the IEEE 497 and its 2016 edition: - some IEC standards were added as normative references; - an additional group of Type F variables was defined to cover parameters providing information to manage fuel damage scenarios and associated technical requirements were given; - several paragraphs were removed from 6.2 of the 2010 edition, which gave requirements on diversity of design and defence in depth; - the term “1E” was replaced by “safety system”. Nevertheless, two major issues for the possible direct adoption of IEEE 497:2016 as IEC/IEEE standard in the frame of the agreement AC/138/2002 were identified: • The absence of reference to any function categorization scheme or system/equipment classification scheme.
