The proposed research will develop experimental expertise at Queen's for testing of graphene oxide membranesas a water filtration system. The long term goal is to develop a system capable of reliably filtering tritium fromheavy water. A computational modelling study will support the research, with the goal of determining theunderlying mechanism for the filtration. This modelling effort will guide a process of optimisation of themembrane through functional additions.Eventually, nuclear reactors must be de-commissioned. The key outcome of this research will be efficientseparation of Tritiated water from the decommissioned heavy water moderator. Efficient filtration has thepotential to make safe storage much easier, and in addition to i) provide separated tritium and heavy water forsubsequent sale; ii) position Canada well to lead the global marketplace for de-commissioning of reactors thatwill be emerging internationally over the next few decades. HQP will gain experience in advanced chemicalfiltration techniques that are also applicable to, e.g. desalination of water.

拟议的研究将在皇后学院开发实验专业知识，用于测试氧化石墨烯膜作为水过滤系统。长期目标是开发一种能够可靠地从重水中过滤氚的系统。一项计算模型研究将支持这项研究，目的是确定过滤的基本机制。这一建模工作将通过增加功能来指导膜的优化过程。最终，核反应堆必须退役。这项研究的关键成果将是从退役的重水慢化剂中有效地分离氚水。高效的过滤有可能使安全储存变得更加容易，并且除了i）为随后的销售提供分离的氚和重水; ii）使加拿大在未来几十年内在国际上出现的反应堆退役的全球市场中处于领先地位。HQP将获得先进的化学过滤技术的经验，这些技术也适用于水的脱盐。
