UK Atomic Energy Authority’s (UKAEA) robotics team, the Remote Applications in Challenging Environments (RACE), supported the testing of agile robots for nuclear decommissioning.

UKAEA’s robotics team RACE was at Sellafield recently to advise and support on how canine-like robots could help the clean-up of Western Europe’s largest nuclear site.

The nuclear power company, Sellafield Ltd, held a three-day trial of Spot, the agile mobile robot developed by Boston Dynamics, at the Calder Hall nuclear power station, which is now being decommissioned.

The building offers challenging terrain in a risk-managed environment, providing ideal conditions to test Spot’s agility, scanning and radiation detection capabilities.

If successful, Spot could be deployed at locations across the Sellafield site to carry out routine tasks like inspections, mapping, data capture and characterisation. The four-legged robot is able to perform autonomous missions and can be controlled remotely via an operator, which significantly improves safety by allowing the robot to enter hazardous, contaminated areas in lieu of a person.

Spot is also expected to speed up inspection times, as robots do not require as much personal protective equipment, and help save money by ensuring more frequent data collection and better predictive maintenance.

The RACE centre at UKAEA’s Culham site owns two Spot devices and has been working on applications for them in industrial locations where it’s difficult or unsafe to send humans. One of its Spots last year carried out a radiation mapping project at Chernobyl for the University of Bristol.
