Non destructive monitoring of mechanical stress in concrete for the survey of nuclear power plants

Jean François Chaix, Vincent Garnier, Rakotonarivo S., Bogdan Piwakowski, C. Ciccarone, Jean-Marie Henault, Odile Abraham, Géraldine Villain, Xavier Dérobert, G. Gugole, Olivier Durand, J.B. Legland, Jérôme Verdier, Hognon Sogbossi

To prevent consequences of damage in case of accident, some barriers of pre-stressed concrete are included in the nuclear power plant structures. Hence, to insure the nuclear security, it is important to control these structures. The nuclear accident induces pressure and temperature increases. This…

Passive guided wave tomography for pipes inspection

Tom Druet, Huu Tinh Hoang, Bastien Chapuis, Emmanuel Moulin

Structural Health Monitoring (SHM) consists in embedding sensors in a structure like aircraft fuselages, pipes or ship hulls in order to detect defects (for example cracks or corrosion in metallic materials or delamination in composite materials) before a serious damage occurs in the structure.…

Synthesis of lead-free (Bi0,5Na0,5)TiO3 thin film by RF magnetron sputtering

Ahmad Hamieh, Freddy Ponchel, Denis Remiens, Sophie Barrau

This work concerns the growth of (Bi0,5Na0,5)TiO3 on Si/SiO2/LNO by RF magnetron sputtering. We observed, for the first time on BNT thin films, reactions that destroy the film. This behavior is associated to sodium or sodium oxide segregation. After an extensive description of the sodium impact…
