Outline of Final Research Achievements

Accident Tolerant Fuel is being developed, such as SiC cladded fuel rods, in order to increase the grace time of light water reactors in anticipated loss of core cooling accidents. This study aims to reveal behaviors and issues for introduction of such ATF by simulating its behavior in normal operation condition as well as in severe accident condition through multi-scale modeling.
