| Question | Short Answer | |----------|--------------| | | No. RCC‑M is a copyrighted standard. You must purchase it from AFNOR or obtain it via an institutional subscription. | | Is there an English translation? | An official English version (RCC‑M/FR) exists but is also sold by AFNOR. Some nuclear firms have internal bilingual copies. | | Do I need to follow RCC‑M if the component is for a non‑French plant? | If the client or regulator specifies RCC‑M (e.g., French‑designed reactors), then yes. Otherwise, you may use equivalent codes (ASME‑III, EN‑13445). | | What software is “RCC‑M‑ready”? | Any CAE that can import custom material data and perform linear elastic or fatigue analysis. Dedicated nuclear tools (e.g., Code‑Aster , Nuclear FEM packages) often include RCC‑M annex templates. | | How to treat weld residual stresses? | RCC‑M recommends a stress‑relief heat treatment (typically 600 °C for 4 h) for Class‑1 components, or to model the residual stress field using a plasticity‑based FEM and then apply the superposition principle. |

All these records must be stored in a (e.g., ENOVIA, SharePoint with version control) and be available for audit.

Concrete consumption is calculated based on the volumetric dimensions of structural elements.
