Radioactive Waste Management Limited (RWM) is responsible for implementing the management and ultimate disposal of higher activity radioactive waste through constructing and operating a geological disposal facility (GDF).
In 2017, RWM published a set of safety case reports for a future GDF based on its understanding of the scientific and engineering principles supporting geological disposal. A site for a GDF has not yet been identified. The safety case is based on assumptions about possible geological settings, GDF concepts and designs, and is referred to as the 2016 generic Disposal System Safety Case (2016 gDSSC).
The Environment Agency and the Office for Nuclear Regulation have assessed the 2016 gDSSC at the request of RWM, to provide scrutiny and advice on parts of its work ahead of any permit or licence application.
