Ongoing NA project in Japan

The International Bentonite Longevity (IBL) project was launched at the kick-off meeting on 22-23 May, 2019 in Sagae-shi in Japan. The project was introduced at the NAWG-15 workshop in Prague and recent updates presented at the Clay Conference 2022 in Nancy and current progress will be presented at NAWG-17. For future updates follow the website at www.iblproject.com. For further details contact Russell Alexander (This email address is being protected from spambots.

Publication by a NAWG member

Tony Milodowski and his co-authors have described the salinity and redox evolution in a deep coastal groundwater system. The results indicate long-term stability in a deep hydrochemical system despite repeated glaciations and associated sea level changes throughout the Quaternary.

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).
