We have developed a fiber-delivered laser-induced breakdown spectroscopy (fiber-LIBS) system for the remote analysis of nuclear fuel materials inside and outside the reactor in the decommissioning of Fukushima Daiichi nuclear power station. In this study, we evaluated the detection limit of the fiber-LIBS using samples containing unirradiated U, Zr, Fe, etc., and demonstrated the 2D elemental analysis of simulated samples containing spent fuel under a high dose rate environment.
