Would you like to carry out halogen analysis according to RCC-M 2018 F6000 Annex V §C
Ensure the integrity of your nuclear components with rigorous control of chemical contaminants
In the nuclear construction sector, controlling impurities is a safety imperative. FILAB supports you in qualifying your processes and materials in accordance with the strict requirements of RCC-M 2018, Volume I, Section 6, Annex V §C.
RCC-M is the French code that defines the design and construction rules for mechanical equipment in the nuclear islands of Pressurized Water Reactors.
It notably covers design changes, manufacturing follow-up, and inspection for the European Pressurized Water Reactor (EPR).
What does RCC-M 2018 F6000 annex v §c say?
Annex V of Section F6000 (Volume I) of the RCC-M 2018 code is an important normative section dedicated to chemical cleanliness control of materials used in power plants.
Paragraph C defines the requirements relating to the measurement of impurities in consumables and substances likely to come into contact with component surfaces (particularly austenitic stainless steels and nickel alloys).
The objective is to prevent stress corrosion cracking (SCC) and intergranular degradation caused by specific chemical elements.
The elements analyzed
The text requires rigorous measurement of three types of contaminants:
FILAB supports you in your halogen analysis according to RCC-M 2018 F6000 annex v §c
Why is compliance with F6000 mandatory?
RCC-M 2018
Under RCC-M 2018, compliance with §C of Annex V is a sine qua non condition for:
Validation of SDSs (Safety Data Sheets) for products used in the workshop.
Approval of the quality plan by the end customer (EDF/Framatome).
The absence of residual contamination before commissioning (hydrostatic testing and operation).

Our FAQ
Chlorine (Cl) and fluorine (F) are extremely corrosive agents for the noble metals used in the nuclear industry. In the presence of moisture and heat, they can cause Stress Corrosion Cracking (SCC), leading to micro-cracks invisible to the naked eye but fatal to the integrity of the primary or secondary circuit. Sulfur (S), also covered by this annex, can embrittle nickel alloys.
All "consumable products" that come into contact with the surfaces of mechanical equipment in the nuclear island must be analyzed. This includes:
Dye penetrant products: penetrants, developers, cleaners.
Lubricants and machining products: cutting oils, greases, hydraulic fluids.
Marking and protection: marking pens, adhesive tapes, varnishes.
Cleaning solvents: used before welding or after machining.
Although the RCC-M code defines the methodological framework, the limit thresholds often depend on the specifications of the client (EDF, Framatome). However, the standard limits generally encountered are:
Total halogens (Cl + F) : < 200 ppm (parts per million).
Total sulfur (S) : < 200 ppm.
Some specific projects require lower thresholds, down to 50 ppm.
