The Office for Nuclear Regulation has issued an improvement notice to Sellafield Ltd following an incident that occurred during a maintenance outage in April 2025.
During the works, contractors operating under the supervision of Sellafield Ltd were replacing steel ropes on an overhead crane when they became loose and fell to the ground. While no workers were injured and there was no radiological risk, the incident had the potential to cause more serious harm to workers.
The improvement notice has been served following contraventions with Regulations 7(1) and 7(5) of the Management of Health and Safety at Work Regulations 1999, in relation to the provision of health and safety assistance (specifically, supervision).
Sellafield Ltd has until 13 November 2026 to comply with the requirements of this notice.
