An optimum membrane and membrane assembly for the filtration of heavy water containing tritiated heavy water

拟议的研究将在女王大学开发实验专业知识，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。计算模型研究将支持该研究，其目标是确定过滤的潜在机制。这项建模工作将通过添加功能来指导膜的优化过程。最终，核反应堆必须退役。这项研究的主要成果将是从退役的重水慢化剂中有效分离氚化水。有效的过滤有可能使安全储存变得更加容易，此外，i) 提供分离的氚和重水以供后续销售； ii) 加拿大将在反应堆退役方面处于领先地位，该市场将在未来几十年内在国际上兴起。 HQP 将获得先进化学过滤技术的经验，这些技术也适用于，例如水淡化。

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.
