TL;DR: In this paper, a thermochemical water splitting iodine-sulfur (IS) process in Japan Atomic Energy Agency (JAEA) is summarized and a test facility with process design of 100 L/h hydrogen production is performed to verify integrity of process components and stability of hydrogen production.

TL;DR: In this article, a test facility using corrosion-resistant materials was constructed and a trial operation for integration of the sections was successfully conducted to produce hydrogen of about 10 L/h for 8 hours.

TL;DR: In this paper, a test facility has been constructed using corrosion resistant industrial structural materials to verify the integrity of chemical plant components and demonstrate continuous and stable hydrogen production, and a shaft seal technology was developed for a corrosion-resistant pump, which is the key device for feeding HI solution with high concentrations of iodine.

TL;DR: In this paper, the authors present an outline and results of hydrogen production tests by using the test facility and reliability improvements by developing a strength estimation method for heat-resistant and corrosion-resistant ceramics components made of silicon carbide.

TL;DR: In this article, the authors focused on a nondestructive inspection method by which cosmic-ray muons could be used to observe the internal reactor from outside the reactor pressure vessel (RPV) and containment vessel (CV).
