STRUCTURAL INTEGRITY DEMONSTRATION OF HIGH BURNUP FUEL ROD

摘要

This paper introduces the current status and the work has been done for structural integrity demonstration of high burnup fuel in China. The FRAMATOME ANP COCCINEL, FLAMBE and MISTIGRI design codes are used in the structural integrity demonstration of fuel rod.This paper presents the results of structural integrity demonstration of AFA3G fuel rod in GNPS. All the design criterion are met.Based on CAFA program, the new fuel models are planning to be developed in the near future.
