2014:17 Technical Note, Assessment of radiological effects on non-human biota –Main Review Phase
This report presents a review of SKBs assessment of the long-term radiological effects on plants and animals of a deep geological repository as described in SKB report TR-10-08. The SKB report is one of ... any justifiable alternatives were evaluated. A key protection goal of the assessment, as defined by SSM, relates to the value of certain types of species. There appears to have been little ‘special attention’...

2017:12 Computational assessment of LOCA simulation tests on high burnup fuel rods in Halden and Studsvik
in a Light Water Reactor (LWR). The lack of cooling and the drop in pressure impose large stresses on the nuclear fuel which would increase the risk of fuel rod damage and the subsequent release of active ... 5 (see SSM report 2015:37). Objective This report describes the validation of the models against tests performed in Halden and in Studsvik, the latter commissioned by NRC. The objective for SSM in this...

2023:14 Effect of gamma-irradiation on the redox states of the structural iron in bentonite clay
SSM perspective Background Bentonite 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 ... physicochemical properties of bentonite clay, such as swelling. In this study, the focus is on such radiation effect on compacted bentonite. Results Molecular dynamics simulations show that the water radiolysis...

2017:20 Assessment of inertia effects on transient clad-to-coolant heat transfer and coolant flow under reactivity initiated accidents
In this report, simple hydrodynamic models are used for studying the effects of coolant inertia on fuel-to-coolant heat transfer and coolant flow under reactivity initiated accidents in light water reactors ... SCANAIR fuel rod analysis program. The results of our study suggest that inertia has a negligible impact on the growth kinetics of the continuous vapour film that forms between the fuel rod cladding tube and...
