PMUC products (Products and Materials Used in Electric, Nuclear or Thermal Power Plants) potentially have a corrosive action on steels when they contain halogenated or sulfur-containing species.

In order to be authorized to be placed on the market, PMUC products must be approved by EDF, after having been analyzed and tested in an EDF approved laboratory for PMUC.

The products concerned are those that can be used at the Central during manufacturing, assembly, maintenance or technical operations.

There are 24 categories of products classified PMUC by EDF: glues, varnishes / paints, anti-seize, cleaning / decontamination / protection products, plastics, seals, leak detection or sealing products, abrasives …

The PMUC analysis consists of determining the halogen (Fluor / Fluorides, Chlorine / Chlorides, Bromine / Bromides) and sulfur contents of the products and materials intended to enter the Power Plant, according to EDF protocols specific to the product family.

Once the analysis has been carried out, a report is drawn up and sent to the customer to present the results to EDF for the delivery of PMUC approval by EDF.
