CEA initiated a study in 2008 to improve the design rules of fast reactors with French utilities(EDF), French designers (AREVA) and non-destructive examination (NDE) specialists (Aix MarseilleUniversity), focusing on the specific issue of in-service inspection (ISI). Thus, at the end of 2012, the RCC-MRxspecifications for NDEs was enlarged, orienting design and manufacturing choices and rules to account forfuture in service inspection. Due to the complexity of the links between design, materials, access, inspectiontechniques and tools, these rules cannot be considered as strict instructions, but rather as leading to fruitfuldialogue between designers and inspectors. The links between in-service inspection and manufacturing processesand specifications are now being explored in further detail. This article describes the approach and RetDprogram in support of this specific work. This initiative should lead to better connections and compromisebetween design work, material specifications and in-service inspection, called RC-CND rules (Design rulestaking into account NDE requirements).
