Design and Construction Rules for mechanical components of nuclear installations. Addenda included : n° 1 (2013)

Purpose and scope
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.
2012 edition, with the 2013 addenda
An addendum to the RCC-MRx code was produced in 2013, incorporating 48 modification files to reflect feedback on the 2012 edition.

Let’s take part in codes update
AFCEN codes continuously improve considering experience feedback of code users. Do you have a question about interpretation of one code paragraph ? Do you propose a code modification ? or you simply want to share with the industry your experience feedback ? The floor is yours. You may download the corresponding form, fill it and then send it to the concerned sub committee who provides answer. Our target is to answer 100% of request within a delay no longer than 3 months.
