2011:34 Evolution of hydrogen by copper in ultrapure water without dissolved oxygen
from this research was that the experimental difficulties of repeating Hultqvist and co-workers work are considerable and were initially underestimated. The main challenge was to obtain satisfactory tightness ... Nevertheless, experimental work conducted in this project has in principle reproduced parts of Hultqvist and co-workers work. Exposure of copper in pure anoxic water resulted in a measureable gas production rate...

2011:33 Mathematical modelling of ultrasonic testing of components with defects close to a non-planar surface
defect close to a non-planar surface. The studies have been performed in both 2D and 3D, and in 2D in both the anti-plane (SH) and the in-plane (P-SV). The results show that the presence of a non-planar back ... of defects close to the surface. The results show that the corrugated interface can have important, and in some cases, major effects on the signal response. The results depend crucially on the parameters...

2011:32 The Euratom Treaty v. Treaties of the European Union: limits of competence and interaction
Euratom Treaty (promotion of research and dissemination of knowledge; health and safety; encouragement of investment; supplies; safeguards; the nuclear common market) and areas which are in the competence ... (nuclear safety; management of spent fuel and radioactive waste. The Euratom Treaty in comparison with other international treaties and the EU Treaties (TEU and TFEU) has some special features, distinguishing...

2011:30 A fatigue analysis including environmental effects for a pipe system in a Swedish BWR
The effect of the environment on fatigue design has been the subject of intense study in USA, Japan and elsewhere. Several reports indicate a potentially large influence of the environment, leading to the ... fatigue. 100 Kristin Steingrimsdottir and Magnus Dahlberg SSM English The effect of the environment on fatigue design has been the subject of intense study in USA, Japan and elsewhere.

2011:26 The influence of temperature and fluid pressure on the fracture network evolution around deposition holes of a KBS-3V concept at Forsmark, Sweden
about 500 m depth and embedded in 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 biosphere ... (e.g. millions of years), the rock will be subjected to thermal, mechanical and hydraulic changes that can induce failure and propagation of the existing fractures providing new pathways for the spent fuel...

2011:25 Report from SSM’s scientific council on ionizing radiation within oncology, 2010
this report, three main areas have been highlighted: quality assurance (QA), quality control (QC) and late side-effects including the risk of radiation-induced secondary malignancies. These areas reflect ... radiotherapy and intensity-modulated radiotherapy and how these influence QA, QC and late side-effects. Late side-effects of radiotherapy are also discussed in the context of paediatric oncology and radiotherapy...

2011:22 Infiltration of dilute groundwaters and resulting groundwater compositions at repository depth
stability, which may aggravate erosional processes. It is therefore of interest to analyze chemical and physical processes, which affect groundwater chemical composition from the infiltration at the surface ... infiltrating groundwater from a melting glacier may be affected by mixing with older more saline water and matrix water, as well as weathering reactions related to minerals in the bedrock. This report provides...

2011:21 Workshop on spent fuel performance and radionuclide chemistry -Rånäs 2010: Assessment of some outstanding issues
spent nuclear fuel has to comprehensively address the stage when containment barriers have failed and when radionuclide releases occur to the surrounding groundwater at repository depth. Essential processes ... oxidative dissolution of the UO2-matrix, inte- raction between radionu-clides and geologic media as well as secondary phases, and formation of intrinsic actinide colloids. This report descri- bes the outcome...
