Robotics researchers have reached a breakthrough as scientists are able to safely and securely remotely operate a robot on the Sellafield nuclear site, with huge potential for the future of the UK’s nuclear clean-up mission.

Sellafield Ltd is part of the NDA group, which is responsible for decommissioning 17 of the earliest nuclear sites across the UK. For the last two years the UK has used quadrupedal robots through the RAICo programme and its supply chain in its efforts to clean up these sites.

More recently, the UK has worked with AtkinsRealis on the integrated remote monitoring project to deploy a customised Boston Dynamics Spot Quadrupedal Robotic ‘dog’ for a range of tasks including remote inspections, data gathering and clean-up work.

The latest trial takes remote operations a step further by removing the operator from the nuclear site all together, thanks to a highly secure virtual access network and live-streamed footage.

“This successful trial marks a significant milestone in our journey towards integrating advanced robotics into our operations at Sellafield,” Deon Bulman, ROV equipment programme lead at Sellafield Ltd said.

“The ability to remotely operate robotic systems like Spot demonstrates how digital innovation can enhance safety, efficiency, and decision-making on nuclear-licensed sites.

“By collaborating with AtkinsRéalis, we are exploring cutting-edge solutions that not only support our decommissioning mission but also pave the way for future advancements in remote operations.”

This is the first time this type of remote virtual site access has been trialled on a nuclear licensed site, though AtkinsRéalis has already deployed the technology at major construction projects around the world.

“Sellafield Ltd has pioneered the adoption of technology across its operations, and this latest milestone is another step forward for the role of robotics in decommissioning,” Richard Brook, technology solutions lead for decommissioning at AtkinsRéalis said.

“Virtual site access is already being used in the delivery of major infrastructure programmes: this trial is a big step towards unlocking its benefits for nuclear licensed sites without compromising safety or security.”
