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

The proposed research will develop experimental expertise at Queen's for testing of graphene oxide membranes**as a water filtration system. 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. This modelling effort will guide a process of optimisation of the**membrane through functional additions.**Eventually, nuclear reactors must be de-commissioned. The key outcome of this research will be 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 de-commissioning of reactors that**will be emerging internationally over the next few decades. HQP will gain experience in advanced chemical**filtration techniques that are also applicable to, e.g. desalination of water.
