An optimised Graphene Oxide membrane for the filtration of tritiated heavy water

拟议的研究将开发用于水的同位素过滤的氧化石墨烯膜测试的专业知识。长期目标是开发一种能够可靠地从重水中过滤氚的系统。一项计算建模研究将支持这项研究，其目标是确定过滤的基本机制，从而通过功能添加指导膜的优化过程。不同的膜类型将被评估和优化，此外，还将概述从实验室到试点工厂的扩大方法。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。高效的过滤有可能使安全储存变得更加容易，并且除了i）提供分离的氚和重水用于随后的销售; ii）使加拿大能够在未来几十年内引领全球反应堆退役市场。HQP将获得先进过滤技术的经验，这些技术也适用于水的脱盐。

The proposed research will develop expertise in testing of graphene oxide membranes for isotopic filtration of water. The long term goal is to develop a system capable of reliably filtering tritium from heavy water. A computational modelling study will support the research, with the goal of determining the underlying mechanism for the filtration and hence guide a process of optimisation of the membrane through functional additions. Different membrane types will be assessed and optimised, and in addition an approach to scaling up from the lab to a pilot plant outlined.Eventually, nuclear reactors must be decommissioned. The key outcome of this research will be the efficient separation of tritiated water from the decommissioned heavy water moderator. Efficient filtration has the potential to make safe storage much easier, and in addition to i) provide separated tritium and heavy water for subsequent sale; ii) position Canada well to lead the global marketplace for decommissioning of reactors that will be emerging internationally over the next few decades. HQP will gain experience in advanced filtration techniques that are also applicable to, e.g. desalination of water.
