Accident Tolerant Fuel?
The Fukushima accident has prompted the development of several advanced LWR fuel designs. The goal of these “Accident Tolerant Fuel” (ATF) designs is to provide improved robustness during a beyond design basis accident. In the US accident in question is a station blackout (SBO) event. However, the Fukushima accident has also resulted in mandatory plant modifications to mitigate against a SBO. Plant modifications-termed Diverse and Flexible Coping Strategies (FLEX) have been implemented at all US plants. In this talk the various ATF designs will be discussed considering : (1) margin gained during an SBO, (2) margin gained during abnormal and accident events, and (3) cost/benefit considerations related to implementation.
