| 摘 要： | 惰性基质燃料(Inert Matrix Fuel)具有较好的超铀核素销毁能力,是现在广泛研究的新型核燃料之一.为了加速乏燃料中的Pu同位素和次锕系核素MA的销毁及嬗变,本文选取普通PWR栅格作为研究对象,用MC方法比较研究MA加入IMF燃料后对其中子学参数的影响.研究表明,MA的加入会引起堆芯反应性的下降,并在一定程度上使得IMF燃料温度系数和慢化剂温度系数更负.

| Abstract: | Because of the good destruction ability of TRU,IMF fuel becomes one of the new type fuels which is in broad scale researching.In order to increase the destruction and transmutation abilities of Pu isotopes and MA in waste fuels of commercial reactor,we select the normal PWR as the object to study in this article.This essay compares and studies the influence of the neutronic properties of MA added into IMF fuel using MC method.The study shows that adding MA into IMF can reduce the lattice infinite neutron multiplication factors,and to some extent make the fuel temperature coefficient and moderator temperature coefficient more negative. |
