RCC-M, RSE-M and RCC-MRx: A Consistent Set of Mechanical Components Codes and Standards

Abstract

During the past 25 years EDF, AREVA and CEA developed a complete set of Codes and Standards for Nuclear Power Plants inside the French Association for Nuclear Codes and Standards (AFCEN). The list of these Codes are: RCC-M (Design of PWR Mechanical Components), RSE-M (Surveillance and Operation of PWR Mechanical Components), RCC-E (Electrical Components), RCC-G (Civil Engineering), RCC-I (Fire Protection), RCC-C (Design of PWR fuel) and in connection with CEA RCC-MR (Design of HTR Mechanical Components) and RCC-Mx (Design of Experimental Reactor Mechanical Components). This paper will present major Codes for Mechanical Components and the future developments of these Codes. For all these Codes, revisions are generally done every year and are associated to: - needs for new project, - recent R&D results, - regular user requests, - field experience. For all these different disciplines, modernization and State of the Art justification have to be justified. In parallel to that all these Codes have to be used in different international projects, and need some particular developments (as specific appendices) to assure usability under different national regulations and practices.
