2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion
PCO2, SiO2(aq) and Na/Ca in groundwaters (and any future intruding glacial meltwaters) in the near-field at the site. This conclusion would not be evident from modelling approaches using mixing only. Modelling ... suggesting that the buffer may be partially altered prior to glacial meltwater intrusion. David Savage SSM English Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths...

2024:17 Atomistic studies on the adsorption and desorption of radionuclides on fuel crud and system surfaces in Light Water Reactors
SSM perspective Background Radiation safety is of particular concern during power plant maintenance. Radionuclides produced by the neutron bombardment in the core during operation may accumulate on system ... filter system or piping and contribute to the radiation field. Some ions that are prone to neutron capture often become trapped in the deposits on the fuel cladding surfaces, also called CRUD. It is important...

also an analysis of the differences between the electrical and mechanical field especially in the area of independent review. SSM will use the results from the survey to develop the system of independent ... Institute) was merged into one authority - SSM (Swedish Radiation Safety Authority). The publication of the report has been delayed and is now published in the name of SSM. This project was lead by the Department...

2019:04 Dosimetry in environments surrounding a laser-plasma accelerator
SSM perspective Background Modern laser technology makes it possible to generate ultrashort pulses with a very high peak power. At the Lund Laser Centre, a high-power laser facility in Lund, Sweden, laser ... laser pulse whereas the heavier ions largely remain in place, resulting in a very strong electrical field. The research conducted in the field is spurred by the potential to create applications where charged...

2014:30 Modelling Approaches to C-14 in Soil-Plant Systems and in Aquatic Environments
Substantial expertise on carbon biogeochemistry already exists in the fields of plant physiology and aquatic ecology and therefore is it beneficial to draw on this to identify the important issues. A paper ... programme was published in Radiocarbon Journal. Further studies on C-14 (including modelling, model inter-comparisons, and experimental work) have been on-going by individual BIOPROTA member organisations and continued...

2009:16 Influence of Hardening Model on Weld Residual Stress Distribution
Weld residual stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important ... present report is the result of an effort to acquire and to develop the latest research results in the field of WRS and especially the influence of hardening model. The choice of hardening model has been the...

2017:22 Effect of weld repairs on residual stresses in nickel base dissimilar metal welds
affect the residual stresses through e.g. increased tensile stresses and increased plastic straining on the surfaces of the piping in contact with the light water reactor environment. This may in turn reduce ... by numerical simulation with two dimensional axi-symmetric assumptions. Conclusions are drawn based on comparison of the weld residual stresses before and after weld repair. The results show that the inside...

2014:43 Technical Note, Workshop on general corrosion of copper
This report describes the outcome of the workshop organized by SSM on general corrosion of copper that was held in Stockholm on the 26-27th of August, 2013. The report summarizes the issues discussed and ... as opinions rather than SSM’s point of view. Based on the information, arguments and analyses presented in the workshop, it has been concluded that no safety-significant impacts on the general corrosion...
