2021:10 Establishment and use of attention values in environmental fatigue assessments
reach their original technical design life, re-assessment of the fatigue life of structural components is needed for safe long term operation (LTO). In these re-assessments one must consider that new knowledge ... life must be considered. One common method to verify the fatigue life of structural components subjected to an LWR coolant environment is to use so-called attention values. This simplistic method is beneficial...

2016:01 Literature Study on Sparse Channel Interpretation and Modeling
Channelling has been observed in laboratory and field experiments at various scales. However, it is still an open research issue whether a sparse channel network is likely to be a better model than the fracture ... the flow system in fractured rocks. The present report presents a literature study to bring together information useful for addressing this issue. Several key questions are discussed, namely (a) what are...
