METI Project for Development of Technical Basis for Safety Improvement at Nuclear Power Plants
“Development of Technical Basis for Introducing Advanced Fuels Contributing to Safety Improvement of Current Light Water Reactors”
Leader:Japan Atomic Energy Agency
Leader in IAE:Prof. Akihiko Kimura
Project Period:FY2015 ‒
Accident tolerant fuel cladding R&D has been conducted to substitute Zircaloy claddings, which are so reactive with hot water that a lot of hydrogen is produced during accident like Fukushima-I, with Fe-based steel. The FeCrAl-ODS steel modified from “Super ODS steel” has been developed for application to the fuel cladding of BWR.
