Short summary
Bentonite buffer surrounding the waste canister is a critical part of the multi-barrier system for high-level radioactive waste geological repositories that undergo heating from heat-emitting waste and hydration from the host rock. Thus, extensive research was conducted to study the alteration of bentonite due to heating and hydration under high temperatures (200 °C); this work provides valuable data for model validation.
