The RCC-M code, published by AFCEN, is a comprehensive set of design and construction rules specifically for the mechanical components of Pressurized Water Reactor (PWR) nuclear islands. It serves as a critical technical standard to ensure the safety, reliability, and mechanical integrity of equipment like pressure vessels, heat exchangers, and piping systems throughout their design life. 1. Historical Development and Purpose

Originally developed in 1978 by Electricité de France (EDF) and Framatome, the RCC-M code was created to consolidate French industrial experience and feedback from its large-scale nuclear power program. While initially influenced by the American ASME Boiler and Pressure Vessel Code, RCC-M has evolved into a self-contained set of rules that integrates European standards and specific French regulatory requirements. Its primary goal is to provide clear technical guidelines that manage mechanical damage risks such as fatigue cracking, plastic instability, and fast fracture. 2. Structure of the RCC-M Code

The code is organized into five main sections, each addressing a specific stage of the design and manufacturing process:

Section I (Nuclear Island Components): The "key" to the code, classifying components into safety classes (1, 2, and 3) and providing specific design requirements for each. The RCC-M code (Design and Construction Rules for

Section II (Materials): Details the procurement specifications, chemical properties, and qualification requirements for raw materials and parts.

Section III (Examination Methods): Specifies destructive and non-destructive testing (NDT) procedures to verify component quality.

Section IV (Welding): Outlines rules for the qualification of welding procedures, filler materials, and the certification of welders and operators.

Section V (Fabrication): Governs the manufacturing operations, including forming and assembly processes, to ensure compliance with design specifications. 3. Global Application and Access

Beyond France, the RCC-M code is utilized in international nuclear projects, including EPR (Evolutionary Power Reactor) designs in China, Finland, and India. Organizations like the Nuclear Power Corporation of India Limited (NPCIL) have adopted these codes to enhance safety and regulatory trust in their advanced reactor deployments. RCC-M Code - AFCEN

| Check | RCC‑M Clause | How to perform it | |-------|--------------|-------------------| | Allowable Stress (σ_allow) | §4.1 – “Design stress limits” | Retrieve the material’s allowable stress from the RCC‑M material tables (or from the supplier’s certificate). Apply the appropriate temperature factor (k_T) and radiation factor (k_R). | | Thickness Verification (t_min) | §3.2 – “Minimum wall thickness” | Use the formula t_min = (P·R)/(σ_allow·E - 0.6·P) where P = design pressure, R = internal radius, E = joint efficiency (usually 1.0 for seamless). | | Weld Joint Efficiency (E) | §5.1 – “Weld quality” | Choose E = 0.85 for full‑penetration butt welds (qualified) or E = 0.7 for fillet welds, unless a higher efficiency is justified by a welding procedure qualification record (WPQR). | | Fatigue Assessment | §5.4 – “Cyclic loading” | Perform a S‑N curve analysis using the appropriate material class (e.g., 1E, 2E). Use the Goodman or Gerber criteria, with a fatigue factor of safety ≥ 1.5 (per Annex D). | | Thermal‑Shock & Creep | §4.5 – “Thermal loadings” | Verify that the combination of thermal gradient and stress does not exceed the creep‑rupture limit for the service temperature. |

Tool tip: Most CAE packages have built‑in material libraries that can be customized with RCC‑M values. Export the material data to a CSV, then import it into ANSYS/ABAQUS.
