摘要
为了更加充分利用核燃料,在一定的初始燃料富集度和合理地展平功率分布的条件下,达到高燃耗,必须对核供热堆的初装堆芯和换料方式作优化设计,以便实现在给定工况下核燃料循环的最优化和降低燃料成本。叙述了换料优化设计的步骤和倒换料规则,并对低泄漏堆芯和传统的外内装载方式进行了换料优化设计,得到了可供工程设计参考的一种换料优化方案,该方案可提高循环末组件燃耗、降低整个循环过程中的最大功率峰因子。
The initial core and reloading core must be optimized for nuclear heating reactors (NHR) to make full use of the fuel, and increase the burnup under the conditions of given initial fuel enrichment and the power distribution reasonably flatten, so that the fuel cycle optimization is accomplished and the fuel cost is reduced under given operation condition. This paper shows the steps of reloading optimization design and the rules of reloading, optimizes the reloading pattern for lowleakage loading core and traditional outin loading core, and improves an optimal pattern of core reloading which is of important reference value for engineering design. This pattern can increase the burnup of assemblies at the end of cycle, and reduce the maximum power peaking factor during the cycle.
