Short summary
In the Swedish Radiation Safety Authority's (SSM) licensing review of the application to construct and operate a spent fuel repository at the Forsmark site various concerns related to canister degradation processes were brought up. Some of these concerns were initiated by stakeholders and independent scientists. This paper provides a brief summary of a selection of these concerns, and describes how they were dealt with in the review process.
