Assessing volatility during the vitrification of model ILW Wastestreams

将对3种基玻璃系统（硼硅酸盐、硅酸盐和硼铝硅酸盐）中3种具有代表性的模型废液（含碳、含PCM和含Tc）的合并进行技术独立的详细研究。最先进的表征技术，包括熔化过程中的现场测量，将用于确定挥发性演变的动力学以及处理温度、挥发性成分演变、废物掺入率、氧化还原条件和玻璃粘度之间的关系。将开发一个与熔体化学和物理性质与挥发性物质进化动力学相关的模型，为玻璃化技术在ILW废物流固定化中的应用提供基本的科学基础

A technology independent, detailed study on the incorporation of 3 representative model ILW wastestreams (Cs containing, PCM and Tc containing) in 3 base glass systems (borosilicate, silicate and boroaluminosilicate) will be undertaken. State of the art characterisation techniques including in-situ measurements during melting will be used to determine the kinetics of volatile evolution and the relationships between processing temperature, volatile Component evolution, waste incorporation rates, redox conditions and glass viscosity. A model relating melt chemistry and physical properties with the kinetics of volatile species evolution will be developed to provide fundamental scientific underpinning to the use of vitrification technologies in the immobilisation of ILW Wastestreas
