摘要
针对长寿期堆芯的需要,分别开展整体型可燃毒物和分离型可燃毒物的选型研究,并进一步开展了不同类型可燃毒物的匹配研究。研究结果表明:整体型可燃毒物宜采用燃耗较慢的铒、铪等材料;分离型可燃毒物宜采用燃耗较快的钆、硼等材料;合理搭配使用快、慢燃耗可燃毒物,有利于提高长寿期堆芯的综合性能。
Aiming the needs of long-life core, this paper studied the selection of both integrated type burnable poisons and separated type burnable poisons, and also studied the matching of different types of burnable poisons. The results show that： the burnable poisons with lower bumup rate, such as erbium and hafnium, are more suitable for the integrated type; the burnable poisons with higher burnup rate, such as gadolinium and boron, are more suitable for separated type; and the performance of long-life core can be enhanced through a proper matching of burnable poisons with low and high burnup rate.
