Abstract: Device and method for checking fuel rods with IFBA, their zirconium diboride coating. The device includes a variable magnetic field generator and a magnetic field pickup device, arranged in the vicinity of the rod, as well as a control system for comparing both fields in order to measure the electric conductivity of the rod. The method includes the steps of: arranging the rod to be measured between the generator and the pickup device; generation of a variable magnetic field in the generator; picking-up of the magnetic field; comparison between the generated magnetic field and the picked-up one in order to quantify the electric conductivity of the rod; if the electric conductivity differs from a reference value, consider the rod for checking or recycling.

Abstract: Scanner for fuel rods has inspection devices for rods, transport devices to displace the rod throughout the scanner, and indicator devices to generate a signal indicative of a result of a scan corresponding to a scanned rod.

Abstract: An inspection system and method for inspecting a specimen (2) having: a positioning equipment (16) for positioning the specimen (2) in a position according to a desired orientation for inspection, a laser generator (1) for generating shot beams (3) to shoot at the specimen (2), and generating ultrasonics in the specimen (2), a laser detector (5) for detecting the reflected beams (4) from the specimen (2) and generating a detected signal (6), an optical interferometer (7) connected to the laser detector (5) to extract information from the detected signal (6) and translating the information from the detected signal (6) into a measurable intensity modulation signal (8), an acquisition equipment (12) with an A/D converter (10) and a control module (14) for synchronizing the shot beams (11) and the acquisition equipment (12).
