A team of physicists and chemists from the University of Bristol hope to recycle radioactive material directly from a former nuclear power plant in Gloucestershire to generate ultra-long-lasting power sources.
布里斯托尔大学的一组物理学家和化学家希望直接从格洛斯特郡的一座前核电站回收放射性物质,以产生超持久的电源。

Work has begun at Berkeley Power Station in to remove radioactive waste products from the site as part of its decommissioning programme. 
作为其退役计划的一部分,伯克利发电站已经开始从现场清除放射性废物。

By extracting Carbon-14 isotopes from the irradiated graphite, the time and cost of the clean-up operation would be significantly reduced.  
通过从辐照石墨中提取碳-14同位素,清理操作的时间和成本将大大减少。

Berkeley was decommissioned in 1989 and it has only just become safe to start removing radioactive waste products from the plant.
伯克利于1989年退役,开始从工厂中清除放射性废物才刚刚变得安全。
 

These are currently stored in concrete vaults eight metres underground and require specialist equipment to retrieve and process securely.
这些目前存放在地下八米深的混凝土拱顶中,需要专业设备才能安全地检索和处理。

The second nuclear station on the bank of the River Severn is Oldbury, which stopped producing electricity in 2012. This site completed defueling in 2016 and is now in the early decommissioning phase.
塞文河岸边的第二座核电站是奥尔德伯里,该核电站于2012年停止发电。该站点于2016年完成加油,目前处于早期退役阶段。

These two sites, as well as the reactors at Hinkley Point in Somerset and other decommissioned sites across the UK, hold vast amounts of irradiated graphite that hold the Carbon-14 isotope that could be recycled to generate power.
这两个地点,以及萨默塞特郡欣克利角的反应堆和英国其他退役地点,拥有大量的辐照石墨,这些石墨含有碳-14同位素,可以回收用于发电。

University of Bristol researchers have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current. By using Carbon-14 which has a half-life of 5730 years, the batteries could potentially provide power on a near-infinite basis.
布里斯托大学(University of Bristol)的研究人员培育出一种人造钻石,当将其置于放射性场中时,能够产生小电流。通过使用半衰期为5730年的碳-14,电池可以提供近乎无限的电力。

This work is part of the ASPIRE project: Advanced Self-Powered sensor units in Intense Radiation Environments. The lead researcher is Professor Tom Scott from the School of Physics and Director of the South West Nuclear Hub.
这项工作是ASPIRE项目的一部分:强辐射环境中的高级自供电传感器单元。首席研究员是来自物理学院的Tom Scott教授和西南核中心主任。

He said: “Over the past few years we have been developing ultra-low powered sensors that harvest energy from radioactive decay. This project is at quite an advanced stage now and we have tested the batteries in sensors in places as extreme as the top of a volcano!”
他说:“在过去的几年里,我们一直在开发超低功率传感器,从放射性衰变中收集能量。这个项目现在处于相当先进的阶段,我们已经在火山顶部等极端的地方测试了传感器中的电池!

As well as using the batteries in environments where conventional power sources cannot easily be replaced, there are potential applications for medical purposes such as for hearing aids or pacemakers. It could even be possible to power spacecraft or satellites for much further travel than is currently possible.
除了在传统电源不易更换的环境中使用电池外,还有潜在的医疗用途,例如助听器或心脏起搏器。它甚至可以为航天器或卫星提供动力,使其比目前更远的旅行。

Professor Scott added: “The ultimate aim is to have a factory based at one of the former power stations in the South West that takes Carbon-14 isotopes directly from the graphite blocks for use in diamond batteries.
斯科特教授补充说:“最终目标是在西南部的一个前发电站建立一家工厂,直接从石墨块中提取碳-14同位素用于金刚石电池。

“This would significantly reduce the radioactivity of the remaining material, making it easier and safer to manage.
“这将大大降低剩余材料的放射性,使其更容易、更安全地进行管理。

“With the majority of the UK’s nuclear power plants set to go offline in the next 10-15 years this presents a huge opportunity to recycle a large amount of material to generate power for so many great uses.”
“随着英国大多数核电站在未来10-15年内下线,这提供了一个巨大的机会,可以回收大量材料,为许多伟大的用途发电。

This technology is a strong example of the research and innovation being developed in the South West region, the home to the only nuclear new build project in the UK.
这项技术是西南地区正在开发的研究和创新的有力例子,西南地区是英国唯一的核电新建项目的所在地。
