2012:10 Technical Note, Review of the Geomicrobiological Aspects of SKB’s Licence Application for a Spent Nuclear Fuel Repository in Forsmark, Sweden

The Swedish Radiation Safety Authority (SSM) reviews the Swedish Nuclear Fuel Company’s (SKB) applications under the Act on Nuclear Activities (SFS 1984:3) for the construction and operation of a repository for spent nuclear fuel and for an encapsulation facility. As part of the review, SSM commissions consultants to carry out work in order to obtain information on specific issues. The results from the consultants’ tasks are reported in SSM’s Technical Note series.

To evaluate whether the research work by SKB has been adequately comprehensive to describe the influence of microbial activity for sulphide production at repository depth. To document any uncertainties with regard to predictions of rates and consequences of microbial sulphide production.
