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.

S项目的目的是为热等静压(HIP)在钚残渣处理和堆存中的应用提供科学依据。该项目的目标是：在控制PO2的情况下，利用热等静压技术制备候选玻璃/陶瓷废料。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。该项目还将支持热处理技术部署的NDA战略。
