Latest Patents

Gravelle holds a patent for a "Method and device for detecting defective nuclear fuel elements." This invention addresses the critical need for identifying defective fuel elements in assemblies immersed in liquid. The method employs a train of ultrasonic waves, specifically designed to propagate as Lamb waves, which are applied to an end portion of the sheath. The echoes from these waves are detected, and the process is repeated for various frequencies. Some of these frequencies correspond to absorption by water that may be present in the sheath, while others are tuned to detect mechanical defects, such as cracks.
