Technical days

Technical days related to the SBAs (Strategic Business Activities) are organized on a regular basis.

Examples of Technical Days organized by Nuclear Valley:

The HIP Day 2013

With more than 70 participants, the technical information day, organized by Mines ParisTech, SF2M, GFC and Nuclear Valley, was held at Ecole des Mines de Paris and provided the latest information on industrial, scientific and technical advances concerning Hot Isostatic Pressing (HIP).  The powder metallurgy method is used for very large components.

The presentations showed that many industrialists have already opted to use this type of technique for the production of large and heavy cylindrical components, or components with a complex shape. HIP is used for components in the nuclear, aeronautical and Oil & Gas industries.

The day’s presentations clearly demonstrated that the quality of the powder is crucial to obtaining high quality components with a long service life. The techno-economic aspects were also discussed: the gain in material and the resulting microstructure were clearly much better when compared to traditional processes (forging, machining etc.).

“Stainless steels and the nuclear industry, the latest advances”

This technical information day, organized by the Cercle d’Etudes des Métaux, Areva, ARDI Rhône Alpes, SF2M, Viameca and PNB, which was held at the Ecole des Mines de Saint-Etienne, presented the latest industrial, scientific and technical advances concerning the use of stainless steels in the nuclear field for reactors in-service and under construction (pressurized water reactors) as well as for future reactors (generation IV). There were more than fifty participants including many industrialists.

The presentations showed that these materials are extremely important for the civil nuclear industry because their behaviour when irradiated and exposed to thermal, mechanical and chemical stress, determines the service life of existing reactors and also their performance. This approach is equally valid for future reactors functioning at higher temperatures.
