For the decommissioning of Fukushima Daiichi Nuclear Power Station (F1NPS) widely basic R&D and matting for actual application for decommissioning technology will be strongly required. CLADS/JAEA is one of the key institute for strategic promotion of Decommissioning Science on F1NPS in Japan. As for the development of in-situ remote analysis techniques, two kind of R&D will be required. One will be the quick inspection methods of the inventory analysis of nuclear materials contained in small sample of debris. And the other will be the in-situ monitoring / surveillance / analysis of debris based on Laser Induced Breakdown Spectroscopy (LIBS) and related technologies. Especially for under strong radiation, LIBS with radiation resistant optical fiber, so called Fiber LIBS will be the best choice for remote analysis. CLADS/JAEA is now promoting the R&D of LIBS technology for decommissioning and under collaboration with industrial institute for decommissioning work.
