A key contributor of the industrial cladding and guide tube supply chain
The fabrication and distribution process
The Montreuil-Juigné plant transforms extruded hollows manufactured at Framatome’s Ugine site into longer and thinner tubes through a cold pilgering process. After the tubes are pilgered, they are sent mainly to Paimboeuf for the next step in the manufacturing process. The remaining tubes are are subsequently delivered around the world to plants that manufacture cladding tubes and guide tubes.
The transformation operations performed at the Montreuil-Juigné site include pilgering, chemical and thermal treatments, finishing and control operations. Surface treatments require the use of chemical products including hydrofluoric and nitric acid.
Products manufactured at the Montreuil-Juigné site
Tube Reduce after EXtrusion (TREX): blank tubes in the form of Tube Reduced EXtrusion are used to manufacture cladding tubes and guide tubes, which are the key components of fuel assemblies. The manufacturing fabrication and monitoring processes in place are crucial to achieve the properties required for the finished products’ use in the reactor.
