Lyra's exploration of high-risk areas at Dounreay earns recognition from Time magazine
A robot designed with help from Dounreay to safely inspect hazardous environments has been listed in Time magazine’s top 200 innovations of 2022.
The robot, known as Lyra, has been used to inspect ventilation ducts and feedback radiological information from high-risk areas where human access is restricted.
It follows a three-year collaboration between the decommissioning team from Dounreay’s Fuel Cycle Area (FCA), a consortium of universities led by Professor Barry Lennox of the University of Manchester, and knowledge transfer experts at FIS360, to trial a small tracked robot in a nuclear facility.
In 2020, the robotics specialists carried out initial trials in an inactive building, followed by a limited survey within a radiologically contaminated duct in the FCA. As a result of this research, a second-generation robot was developed, which improved on the original robot’s reliability in a hazardous environment.
Between February and April this year, the robot carried out a follow-up survey of a radiologically contaminated underfloor duct that runs under the central corridor between the laboratories.
Dounreay project manager Jason Simpson said: “We are delighted that Lyra has been recognised in this way. At Dounreay we are always looking for technology that will help us to decommission the site, and remotely operated vehicles such as Lyra are ideal for areas that are too small or contaminated for people to access.
"The survey provided us with information that is crucial to informing the way that we will take forward the decommissioning of that area.”
Prof Lennox added: “The trials at Dounreay have been incredibly helpful and not just for the development of Lyra. There are lots of reports describing that robots will transform how legacy nuclear facilities are decommissioned but there remain very few detailed case studies.
“The Lyra deployment has demonstrated to many people in the nuclear industry that robots can be used to solve real nuclear challenges, and it has provided evidence that there can be significant cost savings and reductions in human entries into hazardous environments.
“For Lyra specifically, the trials at Dounreay helped us progress the technology and allowed us to demonstrate that it worked in a real hazardous environment.”
Dr Iain Darby, Dounreay’s innovation manager, said: “The UK is at the cutting edge of pioneering the use of robotics in challenging environments. The experimental nature of many of our sites, now redundant facilities, means the clean-up and demolition requires innovation as well as great care. I’m delighted to see the achievement of the delivery team being recognised by Time – it is a great example of what can be realised when some the of UK's leading specialists collaborate to tackle real world problems.”
Dr Kate Canning, the Nuclear Decommissioning Authority's head of research and development, said: “This has been a win-win, bringing together a range of partners to develop a solution which has benefits for all involved.
"The Dounreay site team were able to really focus on an ideal solution to the challenge, and Manchester’s researchers brought their knowledge and expertise around the complex constraints on the site to develop a technological solution to the problem. Driving innovation and utilising new technologies is vital in helping us deliver our mission to safely and securely clean-up and decommission the nation’s oldest nuclear sites.”
The work was supported by Engineering and Physical Sciences Research Council funding through the Robotics and Artificial Intelligence in Nuclear programme and National Nuclear User Facility for Hot Robotics.
