SELLAFIELD Ltd has pleaded guilty to sending several bags of radioactive waste to the wrong facility.
The company is being prosecuted by nuclear regulators Environment Agency and the Office for Nuclear Regulation after four bags of mixed general waste, such as plastic, paper, tissues, clothing, wood and metal, from normal operations in controlled areas of the site, were sent to Lillyhall landfill site, in Workington.
The bags should have been sent to the Low Level Waste Repository, at Drigg, Cumbria - a specialist facility that treats and stores low level radioactive waste consignments.
Sellafield found the error was caused by a new monitor which had passed the bags as ‘general’ waste making them exempt from strict disposal controls.
All of the original four bags were retrieved from the landfill and returned to Sellafield for correct disposal.
Ian Parker, nuclear regulation manager for the Environment Agency, said: ‘We have carried out a thorough investigation in partnership with the Office for Nuclear Regulation and have already required Sellafield Ltd to take action to ensure this does not happen again.’
Following the guilty plea entered at Workington Magistrates’ Court, sentencing will take place at Carlisle Crown Court on March 8.
