The aim of this collaborative feasibility study between two UK SME's and the University of Cambridge is to investigate the potential of whether a metal matrix ceramic reinforced composite can be used to store low level nuclear waste by developing consolidation and chemical process reactions to densify or consolidate the material. The composite already has high toughness, strength, relatively low density, is thermally stable and is economically attractive. These attributes are well suited to the intended nuclear waste storage application. However, in its standard form, its permeability to aqueous liquids is too high. The objective of this project is to study the potential for reducing the permeability, by low cost modifications to the production procedures using laboratory demonstrations to increase composite density, and to carry out fluid dynamics modelling of the long-term permeation behaviour of the consolidated material. The project is expected to last for 9 months and to result in the development of tough, lightweight, low-cost ceramic composite material for further prototype development of low-level nuclear waste containment vessels.

这两个英国中小企业和剑桥大学之间的合作可行性研究的目的是调查的潜力，是否可以使用金属基陶瓷增强复合材料存储低放射性核废料，通过开发巩固和化学工艺反应致密或巩固的材料。该复合材料已经具有高韧性、强度、相对低的密度、热稳定性和经济吸引力。这些属性非常适合于预期的核废料储存应用。然而，在其标准形式中，其对水性液体的渗透性太高。该项目的目的是研究降低渗透率的潜力，通过低成本的生产程序修改，使用实验室示范，以增加复合材料的密度，并进行流体动力学建模的长期渗透行为的巩固材料。该项目预计将持续9个月，并将开发出坚韧、轻质、低成本的陶瓷复合材料，用于低放射性核废料安全壳的进一步原型开发。
