The RCC-M code was first developed in the 1970s by the French nuclear industry, with the aim of establishing a unified set of design and construction rules for mechanical equipment used in PWRs. The code was initially based on existing French and international standards, but has since undergone several revisions and updates to reflect advances in technology and operating experience. Today, RCC-M is widely used by nuclear operators, designers, and manufacturers in France and other countries.
