| Outline of Final Research Achievements |
A fusion plant concept with a high level of safety characteristics of assuring evacuation-free even for large scale hypothetical events called "upper bounding sequences", was investigated with an emphasis on confinement strategy of mobile radioactive materials and prevention/mitigation systems against the events. It was found that the safety of the fusion plant can be assured for the hypothetical events such as the total loss of coolant accidents, a large-scale loss-of-coolant accident outside the vacuum vessel, etc., when appropriate confinement barriers and mitigation systems are adopted.
