中国实验快堆平衡循环不倒料优化初步研究

Preliminary Study of Loading Patterns Optimization Without Shuffling for Equilibrium Cycle of China Experimental Fast Reactor

摘要: 中国实验快堆现有的平衡循环换料方案由专家经验得到。本工作采用自主开发的快堆堆芯燃料管理优化程序，对中国实验快堆平衡循环进行不倒料优化计算，通过与现有的平衡循环换料方案计算结果比较，对快堆堆芯燃料管理程序进行验证，说明现有的平衡循环换料方案是符合设计限值的较优方案，并给出优化的平衡循环不倒料换料方案。本工作结果表明，自主开发的快堆堆芯燃料管理优化程序可成功用于中国实验快堆的平衡循环不倒料优化。

Abstract: The present loading pattern (LP) for equilibrium cycle of China Experimental Fast Reactor (CEFR) is based on expertise. The code for in-core fuel management of fast reactor, which was independently developed by author, was utilized in this paper to optimize the LP without fuel shuffling for equilibrium cycle of CEFR. The results of comparison between the present LP and optimized LP show that the LP is an optimum one which can meet the present design limits although it can still be improved, and the code for fast reactor is validated to be effective.
