WebAccident tolerant fuels (ATF) are a series of new nuclear fuel concepts researched to improve fuel performance during normal operation, transient conditions, and accident scenarios, such as loss-of-coolant accidents (LOCA) or reactivity-initiated accidents (RIA). Following the Fukushima Daiichi accident, a fuel behavior review was initiated. WebThe nuclear Non-Proliferation Treaty (NPT) does not contain any provisions requiring states to secure nuclear material from theft. Similarly, IAEA “safeguards” are only inspections to ensure that nuclear material is still in civil use, and do not involve any form of international guarding or even international review of the quality of security.
