Matériaux du nucléaire

all technology rests on the choice of materials. More than any other sector, the nuclear industry requires the mastery of issues raised by the behavior of the materials used for building nuclear plants. The reasons are economic but mainly focused on achieving the highest possible safety level. In comparison to other sectors, the nuclear sector has its own constraints: the impact of irradiation on materials properties, the high mechanical and thermal stresses and the difficulty of access. Furthermore, the long periods of time involved require forecasting materials behavior and ageing in the long to very long term.
