2010:42 Using the EPRI Risk-Informed ISI Methodology on Piping Systems in Forsmark 3
based upon the risk for core damage or the risk of release of radioactive substances. Both qualitative and quantitative measures of the relative risk are allowed to be used. So far only the PWRs in Sweden are ... risk procedure based upon the so-called damage index and consequence index. All Nuclear Power Plants in Sweden have a fairly detailed PSA analyses and it is now of interest to find out if such PSA analyses...

2010:40 Rock-block characterization on regional to local scales for two SKB sites in Forsmark – Uppland and Laxemar – eastern Småland, south-eastern Sweden
elevation data in 500m, 50m and 10m grids were used for rock-block interpretations at regional, semi-regional and local scales of areas around the two SKB sites, Forsmark in Uppland and Laxemar in Småland, which ... close to the surface of the sub-Cambrian peneplain and varying altitude may testify to block-faulting in a distorted peneplain. Topographic breaks and changes in the gradient also reveal possible zones...
