In 2007, the CEA, EDF, AREVA launched a coordinated research program for the development of Generation IV sodium-cooled fast reactors (SFR). A R&D program has been defined for the development of ultrasonic (US) techniques in sodium which are required for periodic inspections and continuous monitoring. This program involves both experimentation and modeling of the associated phenomenon. Within the scope of the future ASTRID prototype design, the main milestones until 2012 include validating the ultrasonic transducers, the qualification of in-sodium or out-of-sodium inspection techniques.
