The is the most recent major update as of May 2026, incorporating feedback from modern projects like the EPR (Evolutionary Power Reactor). Key changes include:
RCC-M code ("Règles de Conception et de Construction des Matériels Mécaniques des Ilots Nucléaires PWR") is a French technical standard maintained by rcc-m pdf download
[ ] 1. Acquire official RCC‑M PDF (AFNOR purchase / library) [ ] 2. Draft Requirement Specification (loads, material, class) [ ] 3. Build parametric solid model (respect min radius, hole spacing) [ ] 4. Assign RCC‑M‑approved material data (σ_allow, k_T, k_R) [ ] 5. Perform hand calculations: t_min, allowable stress, weld efficiency [ ] 6. Set up FE model (mesh ≤ 0.2·t at critical zones) [ ] 7. Run linear elastic analysis → verify σ_max ≤ σ_allow [ ] 8. If cyclic loads → run fatigue S‑N analysis (Goodman/Gerber) [ ] 9. Prepare DCR, MPF, WPQR, MD, ITP documents [ ]10. Store all files in a controlled repository with traceability matrix [ ]11. Review against RCC‑M checklist (Annex D, §6, §7) [ ]12. Obtain sign‑off from Design Authority / Nuclear Safety Authority The is the most recent major update as
