2012:38 Technical Note, Radiological effects on non-human biota - initial review
The focus of this review was SKB’s assessment of radiological effects on non-human biota in SR-Site according to present regulations and guidance from SSM and it was conducted by Karolina Stark at the ... biota, and the integration of human and non-human biota dose assessment. These gaps question the scientific soundness and quality of SR-Site. Clarifications are also needed regarding the use of the ERICA...

2009:17 Effect of Welding Residual Stresses on Crack Opening Displacement and Crack-Tip Parameters
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 ... evaluating the stress intensity factor K for cracks located in multi-dimensional weld residual stress fields in piping geometries. Another aim is to investigate the accuracy of existing methods to evaluate...

2016:01 Literature Study on Sparse Channel Interpretation and Modeling
Channelling has been observed in laboratory and field experiments at various scales. However, it is still an open research issue whether a sparse channel network is likely to be a better model than the ... discussed, namely (a) what are the evidences of channelized flow in fractured rocks with laboratory and field measurements?; (b) what is the relationship between generalized flow dimensions from well test analysis...

2018:21 Research on Resaturation of Bentonite Buffer
Previous THM-modelling showed that the re-saturation time is strongly dependent on the hydraulic conditions in the near-field of the repository. Moreover, it is difficult to predict the degree of homogeneity ... illustration of homogeneity are important for SSM's judgement of the long-term safety of spent fuel repository. Results This report consists of three parts: (1) Research on Resaturation of Bentonite Buffer – Hydrological...

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...

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...
