Objectives

The need to expand and develop methods for producing, processing, and transmitting energy is now widely acknowledged. These methods are numerous, and include thermal and nuclear power stations, gas turbines, hydroelectric dams, wind farms, fuel cells, gas pipelines, and high voltage power cables. They are becoming more diverse in the quest to optimize the use of all energy sources. They require major investments and have to be designed for a lifespan of at least 25 years. Efforts are also being made to continue operating existing facilities more efficiently. Achieving these goals demands a profound understanding of the current behavior of the component structures and materials of these systems, but also how they behave over long periods in tough operating conditions. The factors governing incidents or accidents also need to be understood in order to guarantee reliability. The Chair will contribute to the growth of knowledge in these areas, whilst training the specialists the industry now needs.

Themes                            

Assessment of infrastructure lifespan (thermal and nuclear power stations, hydroelectric dams…). Study of micro-structural changes in materials, with a focus on deterioration. Assessment of the impact of these changes on infrastructure lifespan. Development of methods and models for predicting deterioration at material and structural scale. Activities are centered more specifically on teaching, with a 3rd year specialization on the engineering curriculum and support for the international “nuclear energy” Masters program. A fund has been established for the allocation of scholarships for excellence.
