The nature and scale of the task to decommission the UKs legacy nuclear facilities inherited by the Nuclear Decommissioning Authority (NDA) has been historically poorly characterised and highly uncertain. A key objective for the NDA is to form a comprehensive understanding of the work to be done and the associated costs. Although uncertainties still remain, the total discounted costs of completing the NDA's mission were estimated in 2013/14 to be £69.4 billion. An understanding of the nature of legacy waste is an essential part of the decommissioning process. This proposal targets the process of locating and identifying the nature of the gamma-ray emitting radioisotopes present in legacy nuclear waste. The ability to locate, characterise and correctly partition the waste is key to this strategy and will contribute to a significant reduction in the costs associated with the decommissioning effort.This knowledge exchange project brings together the University of Liverpool Nuclear Physics Group, STFC Daresbury Laboratory, Canberra UK Ltd and National Nuclear Laboratory (NNL) to develop a field capable gamma-ray sensor, couple it with an existing 3-D vision system and provide control software and reconstruction algorithms for real time image fusion. This system will enable reliable quantification of waste into free-release/low/intermediate level brackets, with the potential to significantly reduce the cost and time of decommissioning.

核退役管理局（NDA）继承的英国遗留核设施退役任务的性质和规模历来不甚明确，而且高度不确定。NDA的一个关键目标是全面了解要完成的工作和相关成本。尽管仍存在不确定性，但2013/14年度完成NDA使命的总折扣成本估计为694亿英镑。了解遗留废物的性质是退役过程的一个重要组成部分。这项建议的目标是确定遗留核废料中放射伽马射线的放射性同位素的位置和性质。这一知识交流项目汇集了利物浦大学核物理小组、STFC达雷斯伯里实验室、堪培拉英国有限公司和国家核实验室（NNL），以开发一种可用于现场的伽马射线传感器，将其与现有的三维视觉系统相结合，为真实的实时图像融合提供控制软件和重建算法。这一系统将能够可靠地量化废物，将其归入自由释放/低/中水平类别，并有可能大幅减少退役的成本和时间。
