摘要
本文通过三维细网程序对所选择的高通量工程试验堆（ＨＦＥＴＲ）参考堆芯作了三维计算，通过已知的实验结果论证了计算结果的准确性，从物理计算分析角度看，ＨＦＥＴＲ元件在不超过最大点燃耗为６７％这个限制值的提前下，盒平均燃耗限值可以由４５％提高到５０％，同时元件的安全性能不变。本文还探讨了进一步加深ＨＦＥＴＲ元件燃耗后带来的巨大效益。
The three dimension computation to the reference core of High Flux Engineering and Test Reactor(HFETR) has been done by the three dimension fine net program FLUX3D. FOR.The computational accuracy has been proved by experimental results. The computation shown that Per fuel assembly average burnup limit of HFETR may be promoted from 45 % to 50 %under the maximum point burnup is still lower than the limit of 67 %, meanwhile the fuel assembly's safety don't be changed. The big benefit from deepening the fuel burnup has been discussed too.
