摘要：

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)O-2 + MgAl2O4 are 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 + MgAl2O4 target are analysed. (C) 1999 Elsevier Science B.V. All rights reserved.
