In February and April 2022, the Lyra robot carried out a survey of the 140m-long underfloor duct which runs under the central corridor between the laboratories.
The technology was developed by teams at Dounreay, the Robotics and Artificial Intelligence in Nuclear (RAIN) Hub and FIS360, and was made available for the survey through the National Nuclear User Facility's Hot Robotics programme.
Now the characterisation survey is complete, a comprehensive picture of the duct will help make informed decisions on how the duct should be decommissioned.
