The synthesis and characterization of the thorium phosphate diphosphate, Th[sub 4](PO[sub 4])[sub 4]P[sub 2]O[sub 7](TPD), has been published previously.(1,2) It has been proposed as a host phase for plutonium and actinides disposal.(3,4) However, we don’t know a lot about its mechanical and thermodynamic properties as well as about their variation with respect to plutonium concentration. Furthermore, its behavior under irradiation is unknown while the threshold displacement energies relative to the a-recoil have never been estimated. Consequently, a theoretical study on these significant questions is actually being carried out, and we present here the first results obtained. © 2000 American Institute of Physics.
