Umo/Zr单片式燃料板起泡行为数值模拟
Numerical Simulation of Blistering Behavior in UMo/Zr Monolithic Fuel Plate
摘要
Abstract
Blister thresholds of fuel plates are a standard to establish the safety margin for research and test reactors.T he thresholds are determined by blister anneal test.In this study,a method was developed for simulating the blistering behavior of UMo/Zr monolithic fuel plates during annealing,and the influence of the number of internal fis-sion gas atoms on the blister height was investigated.The evolution laws were obtained for the Mises stresses and the equivalent plastic strains in the cladding.The research results indicate that it is a critical reason for blistering that plastic strains occur in the cladding part surrounding the vacancy.This study lays a foundation for analyzing the mechanism and critical influence factors of blistering behavior.关键词
