2012:71 Identification of Brittle Deformation Zones and Weakness Zones
In preparation for the review of Swedish Nuclear Fuel and Waste Management Company’s (SKB) license application for disposal of spent nuclear fuel, Swedish Radiation Safety Authority (SSM) is conducting ... 500 m depth and embedded in bentonite clay. Thus, the rock, the clay and the copper canister are acting as barriers in order to retard the possibility of spent fuel to escape the repository and reach the...

2012:70 Process Parameters Affecting Inhomogeneity of Material Microstructure
There’s been a tremendous change in the number, product types, locations, equipment, and manufacturing capabilities of stainless steel producers from the late 1960’s to present. This reconfiguration of ... early 1970’s to the mid 1980’s and continues today. These changes have produced a loss in manufacturing flexibility, due to the inherent constraints created by equipment and plant designs that were customized...

2012:68 Assessment of cost for dismantling of Ringhals 2 PWR
Swedish Nuclear Waste Fund (SNWF). Transparency of and confidence in the process to ensure collection of sufficient funds is fundamental for the acceptance and sustainability of the Swedish model for estimating ... cost of dismantling the Trojan NPP in the U.S. and supported by other benchmark data derived from U.S. dismantling projects underway or completed at the Zion and Rancho Seco NPPs. The conclusions of the study...

2012:67 Technical Note, Hydrogeological modelling of the Forsmark site
tunnels. The principal results consist of hydraulic and transport property estimates for discrete-fracture network (DFN) models on block scales of 50 m and 100 m, including blocks containing representative ... license application. Analytical, geometrical, and permeameter simulation methods are used to give multiple methods for estimating effective properties and understanding the significance of results. Geometrical...

2012:66 Safety Leadership – the managerial art of balancing production pressure and safety
project has been dedicated to investigating and characterizing ‘safety leadership’, set in the context of literature on safety leadership, safety culture and safety management, in order to build a solid ... solid theoretical basis. The authors have delved deeply into the theories and conceptualizations of leadership and analysed this area in order to further the understanding of safety leadership in the light...

2012:65 Technical Note, Review of the Nuclear Criticality Safety of SKB’s Licensing Application for a Spent Nuclear Fuel Repository in Sweden
Swedish Nuclear Fuel and Waste Management Company in 2011 applied to the Swedish government for approval of a proposed solution for disposal of used fuel from Swedish nuclear power reactors and some relatively ... identified for further elaboration. Such issues include safety criteria, safety margins, method validation and potential criticality accident consequences. The overall conclusion is that adequate nuclear criticality...

2012:63 Technical Note, Review of Radionuclide Sorption on Bentonite and Forsmark Bedrock Material
Denna rapport granskar sorption-data för bentonit och berg vilka har använts i säkerhetsanalysen SR-Site. Det kan konstateras att härledningen av Kd-värden har gjorts på ett systematiskt sätt och att presentationen av resultat är uttömmande. Kontroller visar att härledning och överföring av resultat kan betraktas som spårbar. Det...

2012:62 Technical Note, Review of the MARFA Code
requested by SSM to review SKB’s MARFA code and consider whether the technical arguments and assumptions used for developing the code are sound, appropriate and adequate to support its use in SR-Site. This ... the scope and presentation of the verification cases. It is suggested that SSM could carry out a full QA audit of the MARFA development process. The linkage between the flow (DFN) modelling and the transport...

2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion
Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths in Forsmark fractures, with no evidence for removal/dissolution by previous glacial episodes. This natural analogue ... are in equilibrium (steady-state) with montmorillonite and saponite and these minerals may control pH, PCO2, SiO2(aq) and Na/Ca in groundwaters (and any future intruding glacial meltwaters) in the near-field...

2012:60 Technical Note, Handling of climate related issues in the safety assessment SR-Site
research carried out over several decades and is an impressive compilation of data and knowledge of the site of Forsmark. The sections on climate, glaciations and permafrost have developed continuously through ... occurred and some known weaknesses still remain. On the general structure there are some remarks on the way the process is described in the proposal. It is unclear how new research findings can enter and influence...
