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

拟议的研究将发展用于水的同位素过滤的石墨烯氧化膜测试方面的专业知识。长期目标是开发一种能够可靠地从重水中过滤氚的系统。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，从而指导通过添加功能来优化膜的过程。将对不同的膜类型进行评估和优化，并勾勒出从实验室扩大到中试工厂的方法。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地分离氚水。高效过滤有可能使安全存储变得容易得多，此外，i)为后续销售提供分离的氚和重水；ii)使加拿大在未来几十年将在国际上出现的反应堆退役方面处于全球市场的领先地位。HQP将获得先进过滤技术方面的经验，这些技术也适用于海水淡化等。

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.
