综述了锕系元素嬗变惰性基质燃料的研究进展。共沉淀法（CPP），低冲击混合粉末（LMP）和混合颗粒和粉末（MPP）的三种制造路线进行了描述。这些方法已被测试的各种组合的锕系元素的主体材料和惰性矩阵。最受关注的是一种燃料的概念，由一个含锕系元素的主相和尖晶石作为惰性基质。为了了解这种混合燃料类型的相关系和熔化行为的二元相图（Zr，Y，Pu）O2+ MgAl2O4系统正在建模，并提出了一些结果。此外，MgAl_2O_4基惰性基质燃料的热行为进行了研究。测量了多晶尖晶石的热导率，并对UO2+ MgAl2O4靶堆内温度测量结果进行了分析。
A review of the ongoing research of inert-matrix fuels for the transmutation of actinides is given. Three fabrication routes are described, co-precipitation (CPP), low-impact mixing of powders (LMP) and mixing of particles and powders (MPP). These methods have been tested for various combinations of actinide host materials and inert matrices. Most attention is given to a fuel concept consisting of an actinide-containing host phase and spinel as the inert matrix. To understand the phase relations and melting behaviour of this hybrid fuel type the binary phase diagrams in the system (Zr,Y,Pu)O2+MgAl2O4are being modelled and some results are presented. In addition, the thermal behaviour of MgAl2O4-based inert-matrix fuels is investigated. The thermal conductivity of polycrystalline spinel is measured and in-pile temperature measurements of an UO2+MgAl2O4target are analysed.
