PhD in plutonium stockpile immobilisation: Investigating the effectiveness of using Ce, U and Th as surrogates for plutonium

本课题的目的是为热等静压（HIP）技术在钚渣和钚堆处置中的应用提供科学依据。其目标是：在受控的pO 2下通过热等静压制造候选玻璃/陶瓷废物表征Ce、U和Th作为Pu替代物的分配和氧化还原行为建立Ce、U和Th的固溶机制及其作为替代物的有效性。该项目还将支持部署的NDA战略热处理技术。

The aim of this project s to develop scientific underpinning for application of hot isostatic pressing (HIP) to disposition of Pu residues and stockpile. The objectives are to: Fabricate candidate glass/ceramic wasteforms by HIP under controlled pO2 Characterise the partitioning and redox behaviour of Ce, U & Th as Pu surrogates Establish the solid solution mechanisms of Ce, U & Th and their effectiveness as surrogates.The project will also support NDA strategy for deployment of thermal treatment technologies.
