Design and construction rules for fuel assemblies of PWR nuclear power plants
Our documents are under copyright
The RCC-C code contains all the requirements for the design, fabrication and inspection of nuclear fuel assemblies and the different types of core components (rod cluster control assemblies, burnable poison rod assemblies, primary and secondary source assemblies and thimble plug assemblies).
The design, fabrication and inspection rules defined in RCC-C 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 nuclear fuel assemblies and incorporate the resulting feedback.
The code's scope covers:
- Generalities : definitions, standards, management system and treatment of non-conformities,
- Design basis for safety justification,
- Fabrication aspect :
- Materials requirements,
- Qualification requirements for assemblies,
- Qualification requirements for inspection and manufacturing processes,
- Inspection methods,
- Certification of NDT inspectors.
- Situations out of the NSSS.
The new 2018 English version of the RCC-C is an update of the 2017 edition. The changes to the RCC-C code for the 2018 release have focused on the following topics:
- Grid weld inspection,
- Guide thimble welding,
- Pellet inspection method,
- Nickel base alloys,
- Peripheral power suppression assemblies.

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.
