Assessment of Fuel Rod Performance Analysis Code FRIPAC

摘要

摘要: 为有效预测燃料棒堆内辐照行为，需将很多复杂物理现象的形成机理与实验观测相结合，建立合理的计算模型。中广核研究院有限公司开发的燃料棒综合性能分析软件FRIPAC考虑了运行过程中物理、化学、材料、热力学、辐照等综合效应对燃料棒性能的影响，可对堆内燃料棒行为进行合理预测。本文介绍了FRIPAC软件的物理模型，通过与实验数据的对比对软件进行了评估。结果显示，FRIPAC能准确预测芯块中心温度和裂变气体释放，验证了FRIPAC模型的正确性。后续将继续开展气腔体积、包壳腐蚀等模型的评估，并基于评估结果不断优化软件模型。

Abstract: In order to predict the behavior of the fuel rod in reactor, mechanisms and experiment observations of many physical phenomena need to be combined to establish proper calculation models. China Nuclear Power Technology Research Institute Co. Ltd. (CNPRI) recently developed a fuel rod performance analysis code named FRIPAC, which considers the combined effects of physics, chemistry, materials, thermodynamics, irradiation, etc. on the performance of fuel rods during operation. Thus, FRIPAC can predict fuel behavior in reactors reasonably. The physical model of FRIPAC was briefly introduced in this article. The assessment was made based on experimental data. The results show that the prediction of FRIPAC on fuel central temperature and fission gas release is in good agreement with the measured data, which verifies the correctness of the FRIPAC model. For the future work, the FRIPAC is expected to continue with the assessment of internal rod void volume, cladding corrosion, etc. and to continuously optimize the models based on the assessment results.
