Development of Waste Package Evolution Scenarios

Quintessa has assisted Nirex in developing waste package evolution scenarios for the geological disposal of low-level and intermediate-level wastes, as input to investigating the importance of time-dependency and heterogeneity effects on post-closure repository performance*. In addition to a base scenario, seven variant scenario classes have been defined representing combinations of enhanced water flux, altered water chemistry and physical disruption, and scenarios were presented as combined storyboards and timelines. If you would like a copy of the report, please contact Nirex at info@nirex.co.uk.
