BS PD IEC/TR 63123:2017

BS PD IEC/TR 63123:2017 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".
