• 2012:62 Technical Note, Review of the MARFA Code

  As part of SSM’s Initial Review Phase of SKB’s SR-Site safety assessment of the final disposal of spent nuclear fuel at the Forsmark site, Quintessa has been requested by SSM to review SKB’s MARFA code ... use in SR-Site. This Technical Note summarises the findings of Quintessa’s review. The main concern raised in the review is the poor quality of the documentation associated with the MARFA code, in particular...

• 2012:07 Implementation of the Master Curve method in ProSACC

  Cleavage fracture toughness data display normally large amount of statistical scatter in the transition region. The cleavage toughness data in this region is specimen size-dependent, and should be treated ... methodology is a procedure for mechanical testing and statistical analysis of fracture toughness of ferritic steels in the transition region. The methodology accounts for temperature and size dependence of fracture...

• 2012:49 Hydrogeological characteristics of sites for low- and intermediate-level waste disposal

  Forsmark area with its selected two sites and the Laxemar-Simpevarp area with its two sites are broadly similar in terms of lithology, rock ages, and tectonic histories. The two areas differ in terms of degree ... degree of deformation, and tectonic fabric. Some lithologic and tectonic differences are noticeable between the two sites in the Forsmark area and between the two sites in the Laxemar-Simpevarp area. These...
