Room closure response to gas generation and mechanical strength of different waste forms in a bedded salt repository
Materials Research Society Symposium Proceedings
Finite element calculations of the porosity history of a nuclear waste disposal room for transuranic (TRU) waste in a bedded salt formation have been completed. The analyses include a reduced elastic/secondary creep model for the host halite and a nonlinear consolidation model for the crushed salt backfill. Histories were determined for a 2000 years time period starting from the emplacement of room seals.
