| 摘 要： | 西安脉冲堆仪表与控制系统正在进行数字化改造，需要一套动态特性分析程序提供非脉冲瞬态工况下实时变化的功率和燃料温度等参数。本文在以往铀氢锆脉冲堆经典分析程序的基础上，对堆芯物理模型进行了优化和补充，建立了西安脉冲堆动态特性分析模型，开发了可用于非脉冲瞬态工况分析的西安脉冲反应堆动态特性分析程序（XPRDCA），开展了堆上实验，将程序的计算结果与堆上实验结果进行了对比，并研究了燃料温度反应性系数和气隙传热系数对动态特性的影响。结果表明，程序计算结果和堆上实验结果符合较好，采用优化后模型的动态特性分析程序计算速度显著提升。该程序可以用于数字化仪表与控制系统的设计和调试。

| Abstract: | The instrument and control system of Xi’an Pulsed Reactor is under the digitized reconstruction, and the code for analyzing the dynamic characteristics of non-pulse transient conditions is essential to provide the real-time variety parameters such as power and fuel temperature. Based on the previous classical analysis code of UHZr Pulsed Reactor, the model for analyzing the dynamic characteristics is built by optimizing the reactor physical model of the previous code and adding new models, and the Xi’an Pulsed Reactor Dynamic Characteristic Analysis Code (XPRDCA) is developed for non-pulse transient analysis. The experiment on the Xi’an Pulsed Reactor is performed. The calculation results of the code and the data obtained from the experiment are compared, and the effect of the temperature reactivity coefficient and the gap heat transfer coefficient on the dynamic characteristics is studied. The calculation results are in good agreement with the experiment data, and the computation speed of the code with optimized model is remarkably improved, and the code could be applied to the design and debugging of the digital instrument and control system. |
