摘要：
A mechanistic model of fission gas swelling and release has been developed for metallic fuel under operational conditions. This swelling model is based on gas bubble coalescence and growth by gas bubble random and/or biased migration occurring in grain boundaries. The gas release is modeled by open bubbles and tunnel formation. Experimental data are analyzed by this model. The result suggests that the model can predict fission gas bubble growth of metallic fuel.
