In the [Nuclear sector](https://filab.fr/en/sectors-of-activity/laboratory-analysis-nuclear-energy.md), mastering regulatory requirements is an absolute must. The [RCC-M](https://filab.fr/en/our-services/our-analysis-services/halogen-analysis-laboratory/halogen-analysis-rcc-m.md), and more specifically paragraph **S8300**, defines the requirements relating to **[chemical analysis](https://filab.fr/nos-prestations/analyse/analysis-chimiques/) of [metal materials](https://filab.fr/nos-prestations/analyse/laboratoire-caracterisation-des-materiaux/laboratoire-expertise-materiau-metallique.md)** used in the manufacture of nuclear pressure equipment. At Filab laboratory, we support nuclear industry players in the **performance of chemical analysis compliant with RCC-M S8300**, providing reliable, interpretable results that can be used in your regulatory files. ### What is RCC-M S8300? The **[RCC-M](https://www.afcen.com/fr/rcc-m/194-rcc-m.html) (Design and Construction Rules for Mechanical Components of PWR Nuclear Islands)** governs compliance with the materials used in nuclear equipment. Chapter **S8300** specifies: - The **chemical analysis methods** to be implemented - The **elements to be measured** (major elements, minor elements, impurities) - The **requirements for traceability, accuracy, and reproducibility** - The conditions for **qualifying analytical results** ### Our RCC-M S8300 analysis services We carry out **complete and targeted chemical analysis**, strictly aligned with the requirements of RCC-M S8300, across a wide range of metal materials. #### The materials concerned Carbon and low-alloy steels [Nickel alloys](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/laboratory-analysis-nickel-alloys.md) [Austenitic, ferritic and martensitic stainless steels](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/stainless-steel-analysis-iso-3651-1.md) [Nuclear-specific alloys](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/analysis-of-metallic-alloys-for-the-energy-and-nuclear-industry.md) #### The elements analyzed Major elements: C, Mn, Si, Cr, Ni, Mo, etc. Critical impurities (S, P, O, N, H depending on requirements) Alloying and residual elements ### Our technical resources for RCC-M S8300 analysis [### ICP-OES / ICP-MS](https://filab.fr/en/our-technical-resources/laboratory-analysis-icp-icp-ms-icp-aes.md) [### Elemental analyzer](https://filab.fr/en/our-technical-resources/chons-laboratory-analysis.md) [### Optical emission spectrometry (OES)](https://filab.fr/en/our-technical-resources/laboratory-analysis-oes-alloys.md) ## The FILAB laboratory supports you with RCC-M S8300 analysis ### Why carry out an RCC-M S8300 analysis?

Yes. RCC-M is the reference standard for the design and manufacture of mechanical equipment for PWR nuclear islands. Section S8300 is essential to demonstrate the **chemical compliance of the metallic materials** used, particularly in pressure equipment. What types of chemical analysis are required by RCC-M S8300? S8300 requires **quantitative chemical analysis** to verify the exact composition of the materials: - major and alloying elements, - residual elements, - critical impurities (sulfur, phosphorus, carbon, nitrogen, oxygen, hydrogen depending on the case). The analytical methods must be **appropriate, justified and traceable**. Which materials does RCC-M S8300 apply to? RCC-M S8300 mainly applies to: - carbon and low-alloy steels, - stainless steels, - nickel alloys, - specific metallic materials used in nuclear applications. Are the results usable in an RCC-M regulatory file? Yes. The analysis carried out at filab are **documented, traceable and compliant with RCC-M requirements**, so they can be integrated into your technical, manufacturing or regulatory justification files. Do you need an analysis according to RCC-M S8300? Whether for material qualification, supplier acceptance or a technical investigation, our teams support you with a high level of rigor and reliability.
