Planners in Cumbria have given the go-ahead for two new vaults at the UK’s Low Level Waste Repository (LLWR), along with an extension to a third vault.
The news will ensure the future of the facility, near Drigg, until 2050, creating around 120 construction jobs and securing existing roles.
LLWR was opened in 1957 as the only UK location for the disposal of solid waste containing low levels of radioactivity. It provides an essential service for NDA sites as well as other industries that produce low level waste (LLW). More than £100 million has been invested in the site’s infrastructure over the past decade to maintain it as an important national asset.
Many years of work were required to prepare the planning application, approved by Cumbria County Council, including submission of a detailed Environmental Safety Case covering geology, hydrogeology, waste characterisation, waste processing, engineering of the waste vaults, potential radiological impacts, coastal erosion and engagement with stakeholders.
Planning permission also allows the construction of a final cap over existing and new vaults and seven clay-lined trenches, where waste was disposed of before the first engineered vault opened 1988.
Dennis Thompson, Managing Director of LLW Repository Ltd, said:
“We are absolutely delighted. After three years of hard work, millions of pounds of investment, utilising dozens of technical and scientific experts, we submitted a substantive technical document that makes the case that it is safe to dispose of low level waste (LLW) at the site.
We submitted this case to the Environment Agency, and they did the same thing. They spent an additional three years reviewing it in detail. Every calculation, every model, every assumption was re-reviewed by the EA and their experts and they concluded that the case is made. It is safe to dispose of LLW at the LLWR both now and centuries into the future.”
