Details

The RCC-MRx code was developed for sodium-cooled fast reactors (SFR), research reactors (RR) and fusion reactors (FR-ITER).



It describes the rules for designing and building mechanical components involved in areas subject to significant creep and/or significant irradiation. In particular, it incorporates an extensive range of materials (aluminium and zirconium alloys in response to the need for transparency to neutrons), sizing rules for thin shells and box structures, and new modern welding processes: electron beam, laser beam, diffusion and brazing.

Edition 2018



The 2018 edition provides the synthesis of three years of developments articulated mainly around two axes:



Development of rules to answer to the projects’ needs from the three communities: high temperature reactors (with initiation of adapting the Code to be usable for the whole GEN IV reactors), research reactors and fusion reactors. As an example, improvement of rules to take into account irradiation, new organization of chapters addressing fast fracture and progressive deformation, finalization of A3 appendix dealing with Eurofer.

Harmonization with other codes & standards.



Edition 2015



This edition reflects feedback on the use of the 2012 edition and/or its 2013 addendum, especially in current projects and mainly the Jules Horowitz reactor and the Astrid project. Examples include the inspection and welding procedures for aluminum, as well as the code’s improvements and new structure relating to components used at high temperatures (design rules, welded assemblies and material properties). Initial feedback on the code’s application also helped analyze and integrate additional data on the Eurofer material used by the fusion community.



Furthermore, this edition pays special attention to ensuring consistency between RCC-MRx and the other reference documents that interact with the code, including RCCM, European and international standards.
