Times Cited Count:12 Percentile:58.36(Chemistry, Physical)An iodine-sulfur process offers the potential for mass producing hydrogen with high-efficiency, and it uses high-temperature heat sources, including HTGR, solar heat, and waste heat of industries. R&D tasks are essential to confirm the integrity of the components that are made of industrial materials and the stability of hydrogen production in harsh working conditions. A test facility for producing hydrogen was constructed from corrosion-resistant components made of industrial materials. For stable hydrogen production, technical issues for instrumental improvements (i.e., stable pumping of the HIx solution, improving the quality control of glass-lined steel, prevention of I precipitation using a water removal technique in a Bunsen reactor) were solved. The entire process was successfully operated for 150 h at the rate of 30 L/h. The integrity of components and the operational stability of the hydrogen production facility in harsh working conditions were demonstrated.

In August 2006, operation of the JMTR in JAEA was terminated due to assessment for the operation continuation decision. As a result of the national discussion, the JMTR was decided to continue operation after necessary refurbishment works. The refurbishment was finished in March 2011.However, in March 2011 just after the completion of the refurbishment, the Great-Eastern-Japan-Earthquake occurred, and the JMTR restart were delayed. On the other hand, based on the safety assessments considering the 2011 earthquake new regulatory requirements for research and test reactors have established on Dec., 2013 by the NRA. After evaluation and analyses to the new regulatory requirements were carried out, an application to the NRA was submitted on March, 2015. After taking measures for the safety requirements and the permission by the NRA, the renewed JMTR will be operated for a safety research of LWRs, basic research for nuclear engineering, industrial use, and education and training.
