Assessing volatility during the vitrification of model ILW Wastestreams

将对3种具有代表性的ILW废气(含Cs、PCM和TC)在3种基础玻璃系统(硼硅酸盐、硅酸盐和硼铝硅酸盐)中的掺入进行独立于技术的详细研究。最先进的表征技术，包括熔化过程中的现场测量，将用于确定挥发分的析出动力学，以及加工温度、挥发成分析出、废物掺入速率、氧化还原条件和玻璃粘度之间的关系。将开发一个将熔体化学和物理性质与挥发性物种演化动力学联系起来的模型，为使用玻璃化技术固定化ILW废水链霉菌提供基本的科学依据

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
