2016:16 Technical Note, Possible influence from stray currents from high voltage DC power transmission on copper canisters
Radiation Safety Authority’s (SSM) review of the Swedish Nuclear Fuel and Waste management company (SKB) license application for a final storage for spent nuclear fuel, SSM has asked for complementary ... high voltage cables on copper corrosion (SSM 2012). SKB therefore has performed an extended study of the effects of high voltage DC power transmission as support for answering SSM. This study has been...

01:48 Effects of Time Pressure and Noise on Non-Destructive Testing
to be used for inservice inspections. A significant part of the qualification concept is requirement on qualification of NDT personnel, as it is commonly understood that the human factors effect the total ... The more detailed objective of that particular research was to study effects of stress conditions on manual ultrasonic testing. Results The results of the study suggest that a little stress pressure...

2013:36 Technical Note, Review and assessment of aspects of the Qeq concept – Main Review Phase
Waste Management Company (SKB) developed to represent transport of dissolved constituents in the near field at the Forsmark site, in particular the Qeq abstraction for diffusive transport. SKB uses the Qeq ... in order to estimate dissolved-species fluxes from the far-field environment to the canister surface and from a canister breach to the far field. To accomplish the review assignment, we (i) reviewed relevant...

2009:22 Alternative modelling of brittle structures in a sub-area of the SKB candidate area at Forsmark, eastern Sweden
repository for spent nuclear fuel. The structures in the rock, together with the regional stress field, affect the mechanical stability of the bedrock and the ground water transport within the bedrock ... chemistry. Together, these factors have influence on the environment within which transport of substances may occur, both in the near- and the far-field of the geological repository. The Swedish Nuclear...

02:41 Comparison of SKB's RES Matrix FEPs with SKI's PID FEPs (pdf 290 kB)
assembled a list of features, events and processes (FEPs), representing the Process System (near-field and far-field), with interactions/influences between FEPs incorporated in a Process Influence Diagram (PID) ... to compare SKB’s RES matrix FEPs and their interactions, with SKI’s PID FEPs (for the near-field and far-field/geosphere) and their interactions. The reversed order comparison is also investigated. For...

2017:12 Computational assessment of LOCA simulation tests on high burnup fuel rods in Halden and Studsvik
Computational assessment of LOCA simulation tests on high burnup fuel rods in Halden and Studsvik 2017:12 Author: Lars Olof Jernkvist SSM 2017:12 SSM 2017:12 SSM perspective Background Loss of Coolant ... in a Light Water Reactor (LWR). The lack of cooling and the drop in pressure impose large stresses on the nuclear fuel which would increase the risk of fuel rod damage and the subsequent release of active...

2016:21 The effect of a glaciation on East Central Sweden: case studies on present glaciers and analyses of landform data
ice age will give the Swedish Radiation Safety Authority (SSM) better prerequisites to assess what impact of a future glaciation might have on a repository for spent nuclear fuel. This report compiles ... compiles research conducted between 2008 and 2015 with a primary focus on 2012-2014. The primary aim of the research was to improve our understanding of processes acting underneath an ice sheet, specifically during...
