The RCC-M (Design and Construction Rules for Mechanical Components of PWR Nuclear Islands) is a French nuclear code published by AFCEN (Association Française pour les règles de Conception et de Construction des Matériels des Chaudières Electro-Nucléaires). Section II of RCC-M covers Material Specifications and is crucial for the procurement, manufacturing, and inspection of materials used in Pressurized Water Reactor (PWR) nuclear components.
