摘要
环形燃料元件小堆是世界上目前比较先进的堆型。研究设计了一个环形燃料元件小堆,开发出适于环形燃料堆计算的软件和方法。采用整组件束棒计算堆芯少群参数的方法大大提高了计算精度。计算了堆芯的有效增殖系数、所有控制毒物的单个价值以及总价值、堆芯从室温到工作温度的温度效应等堆芯参数。结果表明:设计的环形燃料元件堆具有良好的稳定性和安全性,可以作为一代新堆。
Annular fuel is a new type fuel which can improve reactor safety and economics on a large scale. The annular fuel reactor is an advanced type reactor. A small annular fuel reactor has been study and designed, and calculating soft and calculating method fitting for this reactor has been empoldered., too. Especially, the method of calculating reactor core few group parameters introducing regarding whole assembly as a cluster improves precision of calculation so much. Addition, some core key parameters has been calculated. For example, calculating reactor core keel ,the per worth and gross worth of all control poison, the temperature reactivity swing and so on. So that the resulting indicates that the annular fuel reactor has been proven to be stable and safe. It can be a new generation reactor.
