[ ] 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
AFNOR (Association Française de Normalization) is a reseller of AFCEN documents. Their website (www.boutique.afnor.org) offers the same PDFs with French or English versions.
Advantage: AFNOR sometimes offers package deals with other nuclear standards (e.g., RFS, RCC-E for electrical components). rcc-m pdf download
AFCEN offers a subscription tool where you pay only for the sections you need (e.g., Volume B for Class 1 piping, or Volume F for forging materials). Output is a custom PDF. etc. | Part 2
A: RCC-M covers construction; RSE-M (Rules for In-Service Inspection) covers operational maintenance. You may need both. radiation‑embrittlement allowances | Part 2
| Action | RCC‑M Reference | |--------|-----------------| | Load Cases & Service Conditions – pressure, temperature, seismic, wind, handling, etc. | Part 2, §3.1 – “Design loads” | | Material Specification – grade, heat‑treatment, radiation‑embrittlement allowances | Part 2, §4.2 – “Materials and heat‑treatment” | | Safety Class – Class 1 (safety‑important) vs. Class 2/3 | Part 2, §2.2 – “Classification of equipment” | | Lifetime & Inspection Intervals | Part 2, §5.5 – “Design life and maintenance” |
Outcome: A Requirement Specification Document (RSD) that lists all load cases, material grades, permissible stress limits, and inspection regimes.
Below is a practical workflow you can follow, whether you are using a CAD system (CATIA, SolidWorks, Siemens NX) or a dedicated nuclear‑engineering tool (ANSYS, ABAQUS, Code‑Aster). The steps are organized to reflect the RCC‑M design cycle:
