• 2014:05 Technical Note, Assessment of flows to deposition holes – Main Review Phase

  division between highly fractured deformation zones (described in terms of deterministic geometry), and the more sparsely fractured rock (described in terms of statistical geometry). The model for the highly ... fractures, which are randomly located and oriented in a given volume of rock. The population of these plates is described by statistical distributions of geometric and hydraulic properties. Flow is assumed...

• 2013:34 Technical Note, Seismology – Post-glacial seismicity and paleoseismology at Forsmark

  Metoden som SKB använder för att förutse seismisk risk för slutförvaret skiljer sig i två avseenden från gängse förfarande. För det första, förkastningsrörelser inom förvaret är beräknade utifrån numeriska bergmekaniska modeller i stället för genom en Probabilistisk riskanalys för förkastningsrörelse...

• 2013:30 Laser pointers and Eye injuries - An analysis of reported cases

  is related to the impairment of the vision. This type of relationship between an imaginary exposure and a subsequent disability is very useful in the risk assessments that are made in the authority’s supervision ... The purpose of this study was to investigate what dose of laser radiation, in terms of intensity and exposure time, may be associated with eye damages. The study has been limited to unwanted exposures...
