JA10 : Long-term stability of bentonite in crystalline environments

SRA Key Topic	SRA Topic	SRA Topic priority
Technical feasibility and long-term performance of repository components	Long-term stability of bentonite in crystalline environments (Topic 3.9 in the SRA)	High

Explanation of the contents of the activity

A project could consist of several parts:

State-of-the –art summary of knowledge on bentonite buffer stability in the individual programmes and within the EC framework (BELBaR)
Laboratory experiments which would exemplify difficult events/conditions for the buffer in the long-term perspective.
In-situ experiments using expected conditions for the buffer in a repository-type environment.Modelling of laboratory and in-situ experiments
Summary of results and consequences for the programmes involved.

Current on-going work (through EC, IAEA, bilaterally...)

Within almost all individual programmes
SKB/Posiva co-operation
EC FP7-project BELBaR (Bentonite Erosion effects on the Long term performance of the engineered Barrier and Radionuclide Transport).
