2017:19 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures, Phase 2
Background In the design of anchorage equipment in concrete structures the beneficial effects of reinforcement are, in most cases, not considered. The American ASCI 349-06 code opens up for a more detailed analysis where the beneficial impact of reinforcement on anchor capacity can be taken into account. How this analysis can be done is, however, not explicitly described in the code. The...

2018:13 Prestudy - Detectors for variance measurements
Background The understanding of radiation quality requires knowledge about the energy deposition pattern of ionizing radiation on which models for cellular and sub-cellular damage can be built. Experimental data is fundamental in this context for quality assurance and bench-marking of models and simulations. Direct measurements are also of practical importance for radiation quality...

1995:19 Non-destructive Assay of Spent BWR Fuel with High-resolution Gamma-ray Spectroscopy
A method, based on high-resolution gamma-ray spectroscopy, has been developed for verification of burnup, cooling time, power history and, to some extent, the initial enrichment of spent BWR fuel. It is shown that, provided that the power history is known and corrected for, bumup and cooling time can be verified with accuracies within 3% and 60 days, respectively, for cooling times up to about...

2007:44e An Introduction to Nuclear Non-Proliferation and Safeguards
The compendium at hand will be used both within an outside Sweden as course material. It is partly a result from the work done by TKM (Training and knowledge management), which is a working group within Esarda (European Safeguards Research and Development Association) that on a yearly basis educates students from all over Europe. The intention is that the material shall be used in conjunction...

2007:43 ProLBB - A Probabilistic Approach to LeakBefore Break Demonstration
The SKI regulation SKIFS 2004:2 allows for the use of Leak Before Break (LBB) as one way to provide assurance that adequate protection exists against the local dynamic consequences of a pipe break. The way to demonstrate that LBB prevails relies on a deterministic procedure for which a leakage crack is postulated in certain sections of the pipe based on the leak detection capability of the...
