Experts' Meeting on High-Burnup Fuel Behavior Under Postulated Accident Conditions

The Nuclear Regulatory Commission will hold a meeting to further develop a Phenomena Identification and Ranking Table (PIRT) for fuel rod response to loss of coolant accidents (LOCAs). PIRTs have been used at NRC since 1988, and they provide a structured way to obtain a technical understanding that is needed to address certain issues. About twenty of the world's best technical experts are participating in this activity, and the experts represent a balance between industry, universities, foreign researchers, and regulatory organizations. The current PIRT activity is addressing postulated LOCAs in a BWR and a PWR.
