Safety activities in JAERI related to ITER

摘要: Safety design approach, codes and safety-related technology development for construction of the international thermonuclear experimental reactor (ITER) initiated in Japan Atomic Energy Research Institute (JAERI) has been reviewed. approach implementation are focused on inherent high-level passive safety features ITER-FEAT. By such features, escalation abnormal condition to accident can be prevented without any special countermeasures as emergency plasma shutdown system. As a result, primary containment system secondary confinement one proposed achieve ITER objectives. To establish structural unique components, an ad-hoc technical committee organized. The designs vacuum vessel tritium process components have reviewed discussed. Recommendations including some attractive methodologies examinations, taking into account low level hazard potential was given by committee. Another under JAERI Construction Division is discussing seismic isolation. current status R&D activities ongoing accumulation data required assurance analysis also
