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...

2011:19 Experimental evaluation of influence from residual stresses on crack initiation and ductile crack growth at high primary loads
weld-induced residual stresses in some materials, for instance stainless steel welds. The R6-method on the other hand tends to give overly conservative assessment results. The significance of the secondary ... materials within nuclear applications has been studied earlier using an analytical approach by a SSM-financed study (SSM Research Report 2009:27). In that study a deterministic safety evaluation procedure was proposed...

2010:34 The understanding of the formation of valleys and its implication on site characterization: Moredalen and Pukedalen, south-eastern Sweden
Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. In south-eastern Sweden, there ... which is a marked, approximately 7 km long, E-W striking valley that cuts through a plateau (c.140 m a.s.l.), an elevated block of the sub-Cambrian peneplain. There are also more open over-deepened valleys...
