High dose rate metal waste from core internals, such as BWR channel boxes or control rods are stored in fuel pool or site bunker pool. Waste form for final disposal of these high dose rate metal wastes should eliminate water to prevent hydrogen gas which can be caused by radiolysis of water. Toshiba’s newly developed drying system for high dose rate metal wastes enable short drying time and easy maintenance. Toshiba will provide the total system to fabricate the waste form for high dose rate metal wastes.
1st Report) -Thermal Analysis of Bonding Head for Liquid-Crystal Drive IC's-Koichi TAMAI, Hironori TAKABAYASHI and Takashi TAKAHASHI High definition and low cost are needed to further widen the use of liquid crystal displays. High-definition liquid crystal can be achieved by improving the mounting accuracy of tape carrier packages (TCPs), which are ICs that drive liquid crystal.Low-cost liquid crystal can be achieved by mounting the multiple TCPs at a time to enhance productivity. Important development challenges in accomplishing these two tasks are high precision and soaking of the bonding head in the TCPs system. An optimum bonding head shape has been obtained by thermal analysis using the finite element method (FEM).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
