The 2018 edition of the RCC-MRx Code will be issued, by the end of the 2018, in French and English versions by AFCEN (Association Francaise pour les regles de Conception et de Construction des Materiels des Chaudieres Electro-nucleaires). This Code set up rules applicable to research reactor components (coming from the RCC-MX 2008 developed in the context of the Jules Horowitz Reactor project), and to components operating at high temperature and to the Vacuum Vessel of ITER (coming from the RCC-MR 2007).This edition takes the beneficial of an important feedback of the users, such as Jules Horowitz reactor or Astrid project, but also from ITER and MYRRHA projects. In parallel, in compliance with the EC's objectives and its own policy of openness, AFCEN proposes to make its codes evolve, taking into account the needs and expectations of European stakeholders (operators, designers, constructors, suppliers) threw a workshop called CWA phase 2. The end of the workshop, planned for 2018, allowed to integrate recommendations issued from this work. This paper gives an overview of the realized work and also identifies the work to be done for an development of a standard such as RCC-MRx code.
