The background and recent results of the R&D titled of "Development of laser remote analysis for next generation nuclear fuel and applied study by MOX sample" entrusted to Japan Atomic Energy Agency by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) will be summarized as the first speaker of the series lecture consist with four titles. We had developed the laser remote spectroscopy system in the glove box at NUCEF facility in JAEA, and applied to oxide samples of Pu, U and Pu mixed in U. For elemental analysis, quantitative determination by Laser Induced Breakdown Spectroscopy will be demonstrated. For isotopic analysis, isotope ratio of Pu and Pu will be quantitatively determined in U oxide base matrix by ablation resonance absorption spectroscopy. Application for the molten debris in the accident of Fukushima power plant will be also discussed.
