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
conditions of the fault and deformation zone inventory at Forsmark a reactivation potential analysis was carried out. At present-day stress conditions the deformation zones are stable and show no large deformations ... deformations or detected seismicity. Any changes in stress, and in particular increase of differential stress on deformation zones, might cause slip. Therefore, several stress field models have been considered...

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
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 damage being ... 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 that the direct access of sulphide species to...

2014:54 Technical Note, Further Modelling Comparison of Simple Reference Biosphere Models with the LDF Modelling Approach – Main Review Phase
for the Forsmark site under temperate climate conditions were previously developed for SSM’s review and are described in Walke (2014), along with comparisons against SKB’s LDF modelling approach. The current ... capability to represent warm and periglacial climate states. Secondly, to further explore differences between the biosphere dose factors calculated with SSM’s simple models and those calculated using the...

2014:55 Technical Note, Further Reproduction of SKB’s Calculation Cases and Independent
Som en del av säkerhetsanalysen SR-Site presenterar SKB modellresultat som illustrerar kapseln och buffertens säkerhetsfunktioner. I var och en av de fem beräkningsfallen är delar av kapsel och/eller buffert frånvarande i modellen av slutförvarssystemet. Modellresultaten jämförs inte med säkerhetskriterier eftersom beräkningsfallen innehåller...

2014:51 Report from SSM’s scientific council on ionizing radiation within oncology, 2013. MR in radiotherapy - an important step towards personalised treatment?
Imaging is important for radiotherapy and the development of new imaging modalities is closely linked to the evolution of modern radiotherapy. The implementation of magnetic resonance imaging (MRI) in ... patient selection to follow-up and discusses possibilities and difficulties related to the introduction of MRI. The report states that many functional MR-methods are available and if the effort to bring these...

2014:50 Technical Note, A Study of Availability of Fuel Data for Sweden’s Spent Nuclear Fuel
selecting a sample of spent fuel and investigating the information available at the Nuclear Power Plants (NPP’s) in Sweden, the Central interim storage facility (Clab) and Studsvik. The results indicate ... required data is available and can be obtained for fuel unloaded after 1980. For fuel unloaded before 1980 most data can be retrieved but all data are not stored digitally and require some effort to retrieve...

2014:47 Technical Note, Assessment of groundwater salinity evolution at repository depth and especially the impact of dilute water infiltration
expected changes of topographic and climatic conditions at Forsmark. This is a long-term safety issue because very dilute water could destabilise compacted bentonite and erode buffer, leading to advective ... hydrogeological properties of the sparsely-fractured bedrock and the processes of water-rock reaction in shallow infiltration, hydrodynamic mixing and exchange with pore waters in rock matrix will be such that...

2014:46 Technical Note, QA in SKB’s Groundwater Flow Modelling
SR-Site, for the proposed repository at Forsmark. The specific objective is to get an understanding and an assessment of SKB’s quality assurance of the groundwater flow modelling in connection to SR-Site ... of the modelling work and the traceability of the modelling analysis and results through the safety assessment. General QA issues in groundwater flow modelling were identified and the QA review focused...
