The long-term safety of the Low-level Waste Repository (LLWR) near the village of Drigg, Cumbria was assessed in 2002 and submitted to the regulator, the Environment Agency, as part of a review of the continued authorisation of the facility.
The outcome has been the recognition that key issues need to be addressed to provide a robust safety case for the facility. Failure to make this case could have major implications for the management of LLW in the UK.
Since late 2005, Quintessa has had a major involvement in helping British Nuclear Group, Sellafield Ltd to develop a 'Lifetime Plan' for the LLWR. This provides an integrated approach to tackling the key issues such as:
- Addressing key regulatory requirements for the continued authorisation of the LLWR;
- Supporting the derivation of the Site End State by the Site Stakeholder Group;
- Planning and preparatory work for the next iteration of the Post-Closure Safety Case within an overall Environmental Safety Case; and
- Developing a strategy for key issues such as the potential vulnerability of historic trenches to coastal erosion.
Nexia Solutions have also been working with Quintessa to support aspects of the Plan.
