With over 500 participants this conference covers a wide range of topics, from engineering through to molecular dynamics, and the oral and poster presentations describe work undertaken at the very forefront of science in this area. James presented on two topics: his recent work on modelling iron-bentonite interactions with JAEA, using a more realistic simulation of the iron-bentonite interface; and reactive-transport modelling (undertaken for NWMO) of bentonite-based shaft seals in shale host rocks with saline groundwaters, implementing the Pitzer approach to model solute activity. Claire presented a poster on modelling work undertaken as part of the Long-Term Cement Studies (LCS) project, based on the cement-clay industrial analogue at Tournemire. This work was funded by NDA RWMD and was carried out in collaboration with our Associate, Dave Savage.
