Several types of ceramics are being researched around the world for their use in nuclear waste management. This project will focus on the synthesis of Ca, Ti and Zr based ceramics for the immobilisation of plutonium and high-level nuclear waste in the UK and investigate their response to radiation damage, helium bubble formation and corrosion under controlled conditions. The materials will be investigated using techniques such as EXAFS, GIXRD, IR-ATR, ToF-SIMS and TEM to develop a fundamental understanding of the corrosion mechanisms relevant under geological disposal conditions.

世界各地正在研究几种用于核废料管理的陶瓷。该项目将专注于合成Ca、Ti和Zr基陶瓷，用于固定英国的钚和高放核废料，并在受控条件下研究它们对辐射损伤、氦泡形成和腐蚀的反应。这些材料将使用EXAFS、GIXRD、IR-ATR、ToF-SIMS和TEM等技术进行研究，以对地质处置条件下的腐蚀机制有一个基本的了解。
