Development of hot laboratory facility under the project of advanced infrastructure

JMTR is preparing for its reoperation, and hot laboratory facilities are also promoting the adjustment of post-irradiation test facilities. The improvement plans from FY2010 to FY2011 are as follows: (1) transmission electron microscope for performing a highly accurate analysis that specializes in the local microscopic area of irradiated materials, (2) focused ion beam processing device, (3) improvement of composite type microstructure analysis device such as X-ray photoelectron spectrometer, (4) improvement of high-performance manipulator of visual function-equipped type, for efficiently, quickly, and safely handling microscopic test samples and large irradiation capsules, and the power manipulator for handling large capsules, and (5) improvement of RI extraction cell for extracting molybdenum-99, as the parent nuclide of technetium-99m used as a radiopharmaceutical. The improvement of these cutting-edge devices enables the development of the next generation light-water reactor as well as the research and development utilizing the state-of-the-art equipment, such as technological development of medical RI production, and gives expectations for contribution to the research and development of future technologies.
