| 摘 要： | 基于ABAQUS对UO_2核燃料芯块裂变气体行为做了研究,对两个经典模型:ANS-5.4单阶段模型和两阶段Forsberg–Massih释放模型作了详细描述,重点研究了这两个模型在ABAQUS中的实现及模型与ABAQUS结合时的技术难点。将研究模拟结果与该模型在相应成熟软件中的结果作比较,吻合度很好,验证了基于ABAQUS二次开发方式模拟裂变气体行为方法的可行性。

| Abstract: | The fission gas behavior of UO2 nuclear fuelling pellets was studied principally based on ABAQUS.Two classical models(the single-stage ANS-5.4 model and the double-stage Forsberg-Massih released model) have been described in detail here.We have been focusing on two models implementation in ABAQUS and technical difficulties when combining these models with ABAQUS.It is found that the simulation results are in a nice agreement with the results of the models in the relevant sophisticated software.Moreover,the feasibility of secondary development in simulating the behavior method of fission gas has been verified based on ABAQUS. |
