The proposed research will use U-containing particles found in the environment around the Fukushima Dai-ichi Power Plant as micro-scale representations of fuel debris and corium materials still inside the stricken reactors. By collecting, isolating and studying these particles we can build an improved knowledge base capable of underpinning the decommissioning of these highly degraded nuclear fuels within these damaged reactors (specifically Fukushima Daiichi, but also applicable to the Chernobyl nuclear power plant). There is equally an applicability to UK legacy nuclear sites, for example historic environmental contamination from Windscale or Dounreay. The development of this unique knowledge base will support a reduction in the hazard, cost and timescale of decommissioning, enabling accelerated decommissioning of nuclear sites. This may have a secondary impact of enhancing public acceptance of civil nuclear energy generation and geological disposal of radioactive wastes at an important time prior to the launch of the geological disposal facility siting process. At the same time, this research will build expertise towards the Civil Nuclear and Resilience Directorate's (CNRD) objectives to protect nuclear sites from threats and hazards; ensuring the UK's preparedness for civil nuclear emergencies and ensuring the UK is a leader on non-proliferation.

拟议中的研究将使用在福岛第一核电站周围环境中发现的含铀颗粒，作为仍在受损反应堆内的燃料碎片和堆芯熔化材料的微观代表。通过收集、分离和研究这些粒子，我们可以建立一个改进的知识库，能够支持这些受损反应堆（特别是福岛第一核电站，但也适用于切尔诺贝利核电站）内这些高度退化的核燃料的退役。同样适用于英国遗留的核场地，例如Windscale或Dounreay的历史环境污染。开发这一独特的知识库将有助于减少退役的危险、成本和时间表，从而加快核设施的退役。这可能产生的第二个影响是，在启动地质处置设施选址进程之前的一个重要时刻，提高公众对民用核能发电和放射性废物地质处置的接受程度。与此同时，这项研究将为民用核和复原力局的目标积累专门知识，以保护核设施免受威胁和危害;确保联合王国对民用核紧急情况做好准备，并确保联合王国在不扩散方面发挥领导作用。
