The recently published 'Nuclear Industrial Strategy' (2013) describes clearly the aspirations of the UK government for both 'New Build' power stations and the life extension of existing nuclear fleet within this timeline. Nuclear energy also remains a strategic priority for South Korea with capacity planned to be increased by 59% by 2022. New approaches need to be developed to manage high level (HLW), intermediate level (ILW) and low level waste (LLW) in a sustainable way, as well as methods for dealing with unresolved legacy issues. This project combines the talents and capabilities within South Korea and the UK to develop solids phase materials that actively target and extract radioactive metals from nuclear wastes. This material is capable of concentrating radioactive metal ions from large volumes of waste in which the problematic radioactive metal ion may be present in small quantities. As an example, rather than sending LLW straight to the Low Level Waste Repository (LLWR) in Cumbria, these solid phase materials can be utilised as a method of waste treatment removing the radioactivity of the LLW so it can be safely disposed of in a landfill. This approach will extend the operational life of the LLWR, where space is limited.Solid phase extractants like these can be developed to selectively target and scavenge specific radioactive metals ions. This work will look at making new solid phase materials to target and remove specific radioactive metal ions, such a cobalt and strontium. This will be done by changing the groups that bind the metal ions on the surface of the silica solid phase.Work will be carried out to determine how these solid phases, which are silica based, once loaded with radioactive metals can be directly converted into a glass or hybrid glass/ceramic, glass/polymer waste form. Experiments will then determine how this waste form, once made, performs in its ability to safely contain the radioactive material.The solid phase extractants, once developed, have the ability to be applied to a number of different decommissioning and remediation issues, such as cleaning up legacy cooling pond sludges or decontamination of soil and ground water.The results from this work will extend the applicability of selective extractants and their use into other areas, while at the same time broadening and cementing collaboration ties between South Korea and the UK in the development of decommissioning technology for future nuclear strategy.

最近发布的“核工业战略”（2013）清楚地描述了英国政府在这一时间表内“新建”发电站和延长现有核电站寿命的愿望。核能仍然是韩国的战略重点，计划到 2022 年将产能增加 59%。需要开发新方法来管理高放废物 (HLW)、中放废物 (ILW) 和低放废物 (LLW)可持续的方式，以及处理未解决的遗留问题的方法。该项目结合了韩国和英国的人才和能力，开发可主动靶向并从核废料中提取放射性金属的固相材料。该材料能够从大量废物中浓缩放射性金属离子，其中可能存在少量有问题的放射性金属离子。例如，这些固相材料可以用作废物处理方法，消除低放废物的放射性，从而可以将其安全地处置在垃圾填埋场，而不是直接将低放废物直接发送到坎布里亚郡的低放废物处置库（LLWR） 。这种方法将延长空间有限的 LLWR 的使用寿命。可以开发此类固相萃取剂来选择性地瞄准和清除特定的放射性金属离子。这项工作将着眼于制造新的固相材料来瞄准和去除特定的放射性金属离子，例如钴和锶。这将通过改变二氧化硅固相表面上结合金属离子的基团来完成。将开展工作以确定这些基于二氧化硅的固相一旦负载放射性金属后如何直接转化为玻璃或混合玻璃/陶瓷、玻璃/聚合物废料形式。然后，实验将确定这种废物一旦制成，其安全容纳放射性物质的能力如何。固相萃取剂一旦开发出来，就能够应用于许多不同的退役和修复问题，例如清洁处理遗留冷却池污泥或净化土壤和地下水。这项工作的结果将扩展选择性萃取剂的适用性及其在其他领域的使用，同时扩大和巩固韩国和英国之间的合作关系开发未来核战略的退役技术。
