一体化增殖燃烧堆双向递推式倒料方案研究

摘要：一体化增殖燃烧堆利用自身的增殖特性，在堆芯内实现核燃料增殖和燃烧的一体化利用。其实现途径之一是将堆芯的燃料布置固定，而增殖燃烧波逐渐移动的行波堆概念，另一种则是通过定期倒料，保持堆芯内燃烧区相对固定的驻波堆。对于驻波堆，需要通过合理的堆芯布置与倒料方案来平衡燃料的燃烧和增殖过程，从而维持堆芯在整个寿期内的稳定运行。提出的双向式堆芯布置与倒料方案中，堆芯中心为燃烧区，燃料组件由内向外依次倒料，而在堆芯外围是增殖区，燃料组件由外向内依次例料，该方案可以保持堆芯在整个反应堆寿期内具有稳定的功率分布。另外双向遵推式堆芯布置与倒料方案最终的组件卸料燃耗是相对均衡的，所有从燃烧区例出的组件都具有相近的燃耗，一般在30%左右。这
使得一体化增殖燃烧堆可以在不进行燃料后处理的条件下，实现轴资源的高效利用。关键调：增殖燃烧堆；双向递推；倒料方案

Abstract: The breed-and-burn reactor can achieve the integrated using of nuclear fuel by breeding and burning successively. The first way of achieving breed-and-burn reactor is the travelling wave reactor, which has moving breeding-and-burning wave and static fuel in the core, while the second way is to keep a standing wave by periodically shuffling fuel within the core. To maintain long-term stability of the core status, the appropriate core layout and shuffling strategy are needed to balance the burning and the breeding of the assemblies. In the proposed bidirectional shuffling strategies, the core area was divided into inner burning region and outer breeding region. Assemblies of burning region shuffled from the core center, while assemblies of breeding region shuffled towards the core center. This shuffling strategy keeps the stable of power distribution in the whole life of the core. Moreover, at the end of the core life, fuel assemblies have
