2023:14 Effect of gamma-irradiation on the redox states of the structural iron in bentonite clay
clay is used as buffer and backfill material which form engineered barrier in the spent fuel repository. The buffer material surrounding the copper canister will be exposed to gamma and neutron radiations ... bentonite. Results Molecular dynamics simulations show that the water radiolysis products H2O2, HO• and HOO• are neither strongly interacting nor strongly excluded from the interlayer regions of montmorillonite...

2023:11 Study of degradation of spent fuel’s structural material and core components under long-term wet storage
Background Sweden is managing the spent nuclear fuel and core components from its commercial nuclear reactors with a national strategic plan. The fuel and core components are initially stored at the reactor ... reactor site. After an on-site storage period to comply with transportation limits on decay heat and radiation, these materials are shipped to the Clab (Central Interim Storage Facility for Spent Nuclear Fuel)...
