Exhaustive studies on external events that may pose a threat to the structures of nuclear facilities and evaluations of the structural integrities are critical to safety. One of the components that greatly influence the behavior of the plant structure is the connection of structural members. In particular, the modeling of the connections has relied on empirical methods, and been conservatively designed and evaluated by considering them as pinned or rigid connections. Therefore, in this research, we have aimed to develop a connection modeling method that reproduces more realistic behavior by utilizing a three-dimensional model of the connection. As the first step of this research, we planned to determine the stiffness of the connections of steel structural members. The results confirmed that the connection can be regarded as a partially-restrained connection depending on the connection specifications of the structure, and the prospects for realistic stiffness evaluation of the connection were determined.

The research and development program of the IS process using the membrane technology and solar heat is now on progress aiming at improvement of the hydrogen production efficiency up to 40%. In the H
SO
decomposition reaction process, oxygen production process, the decomposition rate of sulphur trioxide (SO
) is expected more than 80% at the reaction temperature of 800 - 900
C. On the other hand, the decomposition rate of SO decreases to around 30% in the reaction temperature of 600C which temperature will be provided by solar heat, ceramic oxygen permselective membrane and catalyst have been developing to promote SO decomposition in the reaction temperature of 600C. In addition, the ceramic hydrogen permselective membrane and catalyst to promote HI decomposition for hydrogen production, the cation-exchange membrane and catalyst to reduce amount of iodine in the HI circulation process. Also, the corrosion-resistance material to use metal components in the HSO decomposition process is underway.
