Potential interaction of alkali leachates on repository performance

Posiva, Finland, have recently released a new assessment of the potential impact of alkali, cementitious leachates from their L/ILW repository on their SF repository. The new study, Posiva Working Report 2017-03 (which can be downloaded here), builds on information from several NA studies, including work in Jordan (Maqarin) and Northern Ireland (Scawt Hill).
