1996:70 Risks from Nuclear Waste
The first part of this review discusses the importance of risk. Man seems to have a longing for risks, like a part of the human nature. If risks are missing, they have to be invented, as needed parts in the emotional attraction of sports, amusement parks, traveling, etc.; this is the emotional part of risk. There is also a rational part of risk, in selecting such objects in ordinary life big...

1996:26 Status för gjutet rostfritt stål i äldre svenska kärnkraftverk
En sammanställning av tillståndet för komponenter i gjutet rostfritt stål har gjorts. Bakgrunden till rapporten är de sprickor som upptäckts i ventil- och pumphus i huvudcirkulationskretsarna i Oskarshamn 1. Syftet med det utförda arbetet är att fil en bild av kunskapsläget när det gäller större gjutna komponenter hos i första hand...

1995:70 Crack Characterisation for In-service
During in-service inspection by non destructive testing the reliability is highly dependent on how the equipment is adjusted to the specific object and to the anticipated crack features. The crack feature and morphology vary widely between different cracking mechanisms and between material types, in which the cracks appear. The major objective of this study was to characterise a number of...

1994:14 Evaluation of acceptance criteriafor data on environmentally assistedcracking in light water reactors
The assessment of possible sub-critical crack growth through environmentally assisted cracking (EAC) is a commonly encountered problem in safety evaluations of light water reactor components. The numerous factors influencing EAC fall into three main groups (material, medium and loading), but their interactions are highly complex. Field assessments usually rely on the evaluation of...
