Summary:

This Final Report is, together with the accompanying Data Report (Posiva working report WR 2016-37, one of two top documents summarising the results from the Greenland Analogue Project (GAP). GAP was launched in 2008 when the national nuclear waste management organisations in Sweden (SKB), Finland (Posiva) and Canada (NWMO) joined forces to support the project.

The GAP was initiated to increase the knowledge on glacial hydrological processes and their influence on both surface and subsurface environments relevant to the long term performance of geological repositories for nuclear waste. To this end, a Greenland site, with an existing ice sheet in a crystalline bedrock setting, serves as a natural analogue to future conditions expected for selected repository sites in previously glaciated terrain, such as in Finland.

This Final report presents key findings of the GAP and the increased scientific understanding that has been obtained, whereas the accompanying Data Report (working report WR 2016-37) compiles and evaluates the datasets collected within the project. The results presented in the two reports will be used in ongoing and future safety assessment work performed at Posiva.
