| 摘 要： | SARCS-4程序系统是中国核动力研究设计院自主研发的新一代中子学程序包,需对程序展开工程验证,完善理论模型,提高计算精度。利用成熟燃料元件,设计并制造出与新型燃料组件结构相似的模拟组件。利用模拟组件构造了3种堆芯布置并进行模拟实验,验证SARCS-4程序系统的正确性和可靠性。按照单变量准则和多样化准则,考察控制棒、可燃毒物棒、围板和堆芯布置等因素。模拟实验临界棒位校核分析表明:堆芯泄漏、围板效应、控制棒和可燃毒物棒效应是影响校核精度的主要因素,SARCS-4计算程序系统对模拟实验的整体计算精度相对较高,特殊布置堆芯仍需进一步提高计算精度,后续将通过进一步的实验和研究开展持续验证和改进。

| Abstract: | An advanced neutronic code system, SARCS-4, was developed in Nuclear Power Institute of China. To validate SARCS-4, an experimental program has been carried out. Based on the principles of single factor and variety of critical physics experiment, 3 types of mockup core layout were designed. The effects of control rod, burnable poison rod, shroud and core layout were studied. The calculation and analyses have shown that the core leakage, shroud effect, control rod and burnable poison rod effect are the key factors influencing the calculation precision. The accuracy of SARCS-4 has been confirmed by the mock-up critical physics experiments. Extended experimental program and further validation and improvement of SARCS-4 will be carried out in the future. |
