Abstract

Tailored ceramics are promising potential hosts for the immobilization of actinides [1]. In this study the potential of a range of different ceramic systems were investigated for the incorporation of waste plutonium, using Ce as a Pu surrogate. Durable actinide containing minerals exist in nature and provided excellent target phases for the titanate, zirconate, silicate and phosphate based formulations examined here [2]. The Ce single phase solid solution limits for each system were established and the processing parameters required to produce high quality ceramic specimens were optimised. Importantly, this was achieved within the constraints of a generic processing route suitable for fabrication of Pu bearing samples.
