RCC-M 2012
Reference: AFC32
Design and Construction Rules for Mechanical Components of PWR Nuclear Islands. Addendas included: 2013, 2014, 2015.
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.
The technical publication "Classification of the RCC-M Modification Sheets (MS) up to and including the 2018 Edition (AFCEN-PTAN-09001-2023) accompanies this edition, it is available free of charge in the RCC-M shop.
