2014:57 Technical Note, Issues in the Corrosion of Copper in a Swedish High Level Nuclear Waste Repository: Phase III. Role of Sulphide Ion in Anodic and Cathodic Processes
important findings of this research project show that: In the case when the bentonite buffer between the copper canister and the granitic rock is not damaged, we can neglect the possibility of general corrosion ... corrosion damage being a threat to canister integrity over a 100,000 year storage period. However, if the bentonite buffer is damaged for any reason, and does not act as an engineered barrier, it is predicted...

2011:16 Modelling of ultrasonic testing of cracks in cladding
decades, SSM has supported research to develop a model for the non-destructive test situation based on ultrasonic technique. Such a model is important in many ways, for example to supplement and plan experimental ... parametric studies in qualification situation. Modeling can be a useful tool when the inspection system shall be technically justified. Many functions have been added to the model UTDefect and in this step propagation...

2019:15 3D Thermo-Mechanical Coupled Modelling of Thermo-Seismic Response of a Fractured Rock Mass related to the Final Disposal of Spent Nuclear Fuel and Nuclear Waste in Hard Rock
SSM perspective Background When assessing the long-term safety of a repository for spent nuclear fuel it is important to consider future earthquakes. Previous studies by Yoon et al. (2014, SSM Report 2014:59) ... deformation zones using a 2D thermo-mechanical coupled model that uses a Particle Flow Code (PFC2D, Itasca). The 2D approach limits the investigation to horizontal and vertical cross sections of the Forsmark site...

2011:02 The Back-End of the Nuclear Fuel Cycle in Sweden, Considerations for safeguards and data handling
The report is a compilation report consisting of three papers. A safeguards approach for the planned encapsulation facility and the operating final repository is presented in paper 1. Special considerations ... become inaccessible in the final disposal process. A finding according to the paper is that the safeguards approach for the final disposal process should include a gross defect measurement. Furthermore, it...
