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). See also Posiva Working Report 2007-35 (here) and SKB Report 12-17 (here).

 


New NA project in Japan

The International Bentonite Longevity (IBL) project will hold the kick-off meeting on 22-23 May, 2019 in Sagae-shi in Japan. Several implementing and research organisations will attend the workshop and site visit and the project was introduced at the NAWG-15 workshop in Prague and the Clay Conference in Davos in 2017 (see the pdf presentation (2.21 MB) ).
