Supporting Independent Review of SKB’s safety evaluation SE-SFL

The Swedish Radiation Safety Authority (SSM) is tasked with reviewing the safety evaluation of the planned geological repository for long-lived low and intermediate level waste (SE-SFL), as prepared by the Swedish Nuclear Fuel and Waste Management Company (SKB). Quintessa has provided support in undertaking the review.

SE-SFL is the latest safety evaluation of the disposal concept development for long-lived low and intermediate level waste in Sweden (SFL). The purpose of SE-SFL is to provide inputs to the next steps in the development of the repository, in particular, to evaluate the potential for the SFL repository concept to meet regulatory requirements for post-closure safety.

SSM has contracted external experts to support its review of SE-SFL. The general objective has been to support SSM’s assessment of the evaluation, provide feedback on the continued development of the SFL repository concept, and review the continued development of SKB’s approach to assessment-level modelling. Quintessa provided independent reviews of SKB’s approach to modelling concrete degradation, radionuclide transport in the near-field, and biosphere dose assessment. The findings of these reviews are contained in SSM Report 2021-13.
