摘要：
The stockpile of civil (and weapons grade) plutonium could be reduced if it were incorporated into an Inert matrix fuel (IMF) for insertion in a power reactor However, potential IMF compounds must meet a series of requirements including acceptable thermal conductivity and suitable radiation tolerance Atomistic simulations are employed to investigate properties related to IMF applicability in oxide materials RE2Ce2O7 (where RE = a rare earth atom or Y) pyrochlores In particular, radiation tolerance is predicted through these simulations The theoretical results are then compared to experimental irradiation data in order to determine the applicability of these compounds for further consideration as potential inert matrix fuels
