Nuclear fuel rod cladding decontamination using pulsed laser beam

摘要

The fuel rod cladding is subjected to the impact of a pulsed laser beam from a Nd-YAG laser emitting in the IR range. The process is carried out within an enclosure where the laser is fixed and the fuel rod is moved in translation and in rotation in order to treat the whole surface. A rare gas flow sweeping the rod surface aspirates detached material
