Experts' Meeting on Burnup Credit in Spent Fuel Shipping Casks

摘要

The Nuclear Regulatory Commission will hold a meeting to develop a Phenomena Identification and Ranking Table (PIRT) for allowing burnup credit in spent fuel shipping casks. 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 fifteen 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 PIRT activity is addressing technical issues related to burnup credit in the criticality safety analyses of PWR spent fuel in transport casks.
