Design and Construction Rules for Mechanical Components of PWR Nuclear Islands
Our documents are under copyright
Purpose and scope
AFCEN's RCC-M code concerns the mechanical components designed and manufactured for pressurised water reactors (PWR).
It applies to pressure equipment in nuclear islands in safety classes 1, 2 and 3, and certain non-pressure components, such as vessel internals, supporting structures for safety class components, storage tanks and containment penetrations.
RCC-M covers the following technical subjects:
- Sizing and design rating.
- Choice of materials and terms of procurement.
- Fabrication and control, including:
- Associated qualification requirements (procedures, welders and operators, etc.).
- Control methods to be implemented.
- Acceptance criteria for detected defects.
- Documentation associated with the different activities covered, and quality assurance.
The design, fabrication and inspection rules defined in RCC-M leverage the results of the research and development work pioneered in France, Europe and worldwide, and which have been successfully used by industry to design and build PWR nuclear islands. AFCEN's rules incorporate the resulting feedback.

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.
