2014:59 Technical Note, Relation between earthquake magnitude, fracture length and fracture shear displacement in the KBS-3 repository at Forsmark – Main Review Phase
spent nuclear fuel at the Forsmark site. Two sources of threat are: i) events due to thermal loading on the rock mass by the heat from canisters with spent nuclear fuel, and ii) seismic events, i.e. earthquakes ... the shear displacement on rock fractures induced either by the eff ect of thermal loading, or by an earthquake at a nearby deformation zone, or by the combination of the two. In SKB’s safety assessment SR-Site...
