2013:01 Validation of Weld Residual Stress Modeling in the NRC International Round Robin Study
Weld residual stresses (WRS) have a large influence on the behavior of cracks growing under normal operation loads and on the leakage flow from a through-wall crack. Accurate prediction on weld residual stresses is important to make proper decisions when cracks in weld joints are detected. During the latest years, there has been a strong development in both analytical procedures to...

2013:31 Aesthetic ultrasound devices – current state of knowledge and suggested measurement set-up for characterization of exposure
This report concerns the ultrasound devices used for the aesthetic purposes of body contouring and fat reduction (ablation of adipose tissue). Such devices have recently become more frequent on the Swedish market. These ultrasound devices are currently not medically regulated in Sweden and little is known about their safety and potentially harmful exposure when using them. This report aims to...

2013:30 Laser pointers and Eye injuries - An analysis of reported cases
The safety limits that exist for human exposure of laser radiation are essential to reduce the risk of injuries. These values, however, give very little information on what tissue damages that may be expected at various elevated exposure levels. Similarly, the Swedish Radiation Protection Authority (SSM) has very little information on how such tissue damage is related to the impairment of the...

Tubbrott i en tryckvattenreaktor
Svenska tryckvattenreaktorer har tre ånggeneratorer som innehåller tusentals tuber. Tuberna är en säkerhetsbarriär mellan kärnkraftverkets primär- och sekundärkrets.Om en tub går av måste reaktorn stoppas och den skadade ånggeneratorn isoleras. Faktabladet beskriver vad som händer vid ett tubbrott i en tryckvattenreaktor.
