Scientific objectives are:1. To deploy and refine advanced monitoring technologies for simultaneous imaging of THMC variables (pH, temperature, pore-water pressure, swelling etc) within the laboratory. We will embed state-of-the-art micro-to-nano scale wireless devices into bentonite, and combine these with micro-scale geophysical and magnetic monitoring surveys, to illuminate 2D and 3D heterogeneities in THMC behaviour.2. To integrate these monitoring technologies with experiments to gain a predictive understanding of the THMC evolution of clay-based engineered barriers, and their interfaces, up to the upper-bound of realistic environmental conditions. Interfaces will comprise joints within the clay as well as interfaces to the surrounding rock, cement and waste container. Experiments and modelling will focus on the effects of strong gradients in temperature (<150 degrees C), low pH cements and high salinity (10-40 g/l) across the EBS interfaces, and on the fingering of flow along joints and interfaces that may give rise to a heterogeneous THMC system response.

科学目标是：1。部署和完善先进的监测技术，用于在实验室内同时成像THMC变量（pH值，温度，孔隙水压力，膨胀等）。我们将把最先进的微纳米级无线设备嵌入膨润土中，并将其与微尺度地球物理和磁监测调查相结合，以阐明THMC行为的二维和三维非均质性。将这些监测技术与实验相结合，以获得对粘土基工程屏障及其界面的THMC演变的预测性理解，直至现实环境条件的上限。界面将包括粘土内部的接缝以及与周围岩石、水泥和废物容器的界面。实验和建模将重点关注EBS界面上的强温度梯度（<150℃）、低pH水泥和高盐度（10-40 g/l）的影响，以及可能引起非均质THMC系统响应的沿节理和界面流动的指向。
