摘要
编制了计算氧化物燃料快堆在超功率事故下的动态过程的仿真程序ＯＸＴＯＰ，用它对美国氧化物燃料快堆ＣＲＢＲＰ在满功率运行工况下的３个超功率过程进行了分析计算，结果与国外程序ＦＯＲＩＤ的相应计算值基本符合。以此为基础，对我国首座试验快堆ＦＦＲ在满功率运行工况下的４个假想超功率过程，也作了初步的分析计算，探讨了ＦＦＲ在给定反应性引入速率下的瞬态安全性。
A program OXTOP has been developed for the dynamic simulation of transient overpowersituations in oxide-fueled LMFBRs. It has been used to compute three reactivity insertion eventsat full power condition for CRBRP,The results are in agreement with those predicted by a foreignlarge program FORE-Ⅱ.Based on that, it has also been used to simulate four reactivity inser-tion events at full power condition for FFR, The results demonstrate that FFR has excellent safety characteristics during the four reactivity insertion events if there are effective protection Scrams.
