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’...

2014:11 Technical Note, Radionuclide Solubility Limits in SKB’s Safety Case
The Swedish Radiation Safety Authority (SSM) is reviewing a license application, which has been submitted by Svensk Kärnbränslehantering AB (SKB), for a spent nuclear fuel repository at Forsmark. This ... project that forms part of the main phase of SSM’s license application review. The project involved review of reports and independent modelling studies on issues related to the potential solubility of...

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...

2016:02 Technical Note, An updated review of the creep ductility of copper including the effect of phosphorus
Background The Swedish Radiation Safety Authority (SSM) reviews the Swedish Nuclear Fuel Company’s (SKB) applications under the Act on Nuclear Activities (SFS 1984:3) for the construction and operation ... As part of the review, SSM commissions consultants to carry out work in order to obtain information on specific issues. The results from the consultants’ tasks are reported in SSM’s Technical Note series...

2012:37 Technical Note, Selective review of the hydrogeological aspects of SR-Site
This review of the hydrogeology is selective. It focuses on the measurement, interpretation and modelling of the potential repository host rock, that is the rock domain FFM01<-400m. It accepts as reasonably ... particularly the near-surface 150m in the form presented by SKB. SKB have decided that their main field measurement method is the Posiva flow log. The review notes the speed and efficacy of the method in...

2012:17 Technical Note, Corrosion of copper canister
corrosion is treated in SKB´s safety assessment as being only dependent on oxygen gas and thus easily estimated by an oxygen mass-balance calculation. This simple model has no scientific support since several ... accelerating effect on copper corrosion. Any corrosion model describing the gaseous copper corrosion period must therefore be based on experimental data. Peter Szakálos and Seshadri Seetharaman SSM English It is...

2014:58 Technical Note, Rock Mechanics - Assessing probability and extent of blind faults and fault-end growth around the KBS-3 repository at Forsmark – Main Review Phase
changes in stress, and in particular increase of differential stress on deformation zones, might cause slip. Therefore, several stress field models have been considered in this study. In general, steeply dipping ... simulation results. In addition, this analysis clearly shows that a good understanding of the stress field is essential for any mechanical analysis of geological system behaviour. Simulation of the influence...

2013:37 Technical Note, Rock Mechanics – Evolution of fracture transmissivity within different scenarios in SR-Site – Main Review Phase
shear loading due to SKB’s thermal, glacial and earthquake loading scenarios for the KBS-3 repository at Forsmark. In the first part of the report, SKB’s laboratory experiments on shear fracture dilation ... dilation and extensive literature review on shear fracture dilation in-situ and in laboratory under moderate normal stress show that dilation can become important even under moderate normal stress of about 20...
