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

将进行一项技术独立的详细研究，研究将3种代表性的ILW废水模型（含Cs、含PCM和含Tc）纳入3种基础玻璃系统（硼硅酸盐、硅酸盐和硼铝硅酸盐）。最先进的表征技术，包括在熔融过程中的原位测量，将用于确定挥发物的演变动力学和加工温度之间的关系，挥发性组分的演变，废物掺入率，氧化还原条件和玻璃粘度。将开发一个将熔体化学和物理性质与挥发性物质演化动力学联系起来的模型，为在ILW固化过程中使用玻璃化技术提供基础科学依据
