2014:30 Modelling Approaches to C-14 in Soil-Plant Systems and in Aquatic Environments
carbon biogeochemistry already exists in the fields of plant physiology and aquatic ecology and therefore is it beneficial to draw on this to identify the important issues. A paper describing the BIOPROTA C-14 ... C-14 model inter-comparisons, and plans for the forward programme was published in Radiocarbon Journal. Further studies on C-14 (including modelling, model inter-comparisons, and experimental work) have...

2014:40 Technical Note, Review of Performance Confirmation Programs and Potential Roles in SSM’s Current Review of SKB’s License Application – Main Review Phase
The initial license application of a repository concept for disposal of radioactive waste is based on extensive site characterization, baseline monitoring, development of disposal designs and engineered ... the integration of a series of models representing processes controlling the containment, release and migration of radionuclides from the repository to the accessible surface environment. This information...

2014:57 Technical Note, Issues in the Corrosion of Copper in a Swedish High Level Nuclear Waste Repository: Phase III. Role of Sulphide Ion in Anodic and Cathodic Processes
important findings of this research project show that: In the case when the bentonite buffer between the copper canister and the granitic rock is not damaged, we can neglect the possibility of general corrosion ... corrosion damage being a threat to canister integrity over a 100,000 year storage period. However, if the bentonite buffer is damaged for any reason, and does not act as an engineered barrier, it is predicted...

2014:34 Technical Note, Modelling Comparison of Simple Reference Biosphere Models with LDF Models – Main Review Phase
development of simple reference biosphere models as a means of exploring the Landscape Dose Factor (LDF) approach adopted by SKB in the SR-Site safety assessment for the proposed final disposal of spent nuclear ... fuel at the Forsmark site. The models are developed and described in a systematic manner, based on international guidance reflected in the International Atomic Energy Agency’s BIOMASS approach. The context...

2014:54 Technical Note, Further Modelling Comparison of Simple Reference Biosphere Models with the LDF Modelling Approach – Main Review Phase
further use of simple reference biosphere models for SSM’s review of the Landscape Dose Factor (LDF) approach adopted by SKB in the SR‑Site safety assessment for the proposed final disposal of spent nuclear ... review and are described in Walke (2014), along with comparisons against SKB’s LDF modelling approach. The current study had two objectives. Firstly, to extend SSM’s simple models of the Forsmark site to...

2014:58 Technical Note, Rock Mechanics - Assessing probability and extent of blind faults and fault-end growth around the KBS-3 repository at Forsmark – Main Review Phase
To get a general understanding of the stability conditions of the fault and deformation zone inventory at Forsmark a reactivation potential analysis was carried out. At present-day stress conditions the ... Any changes in stress, and in particular increase of differential stress on deformation zones, might cause slip. Therefore, several stress field models have been considered in this study. In general, steeply...

2014:32 Technical Note, Assessment of the derivation and use of distribution coefficients and concentration ratios – Main Review Phase
This report presents a review of the approaches and databases which SKB have used to derive concentration ratios (CRs) and distribution coefficients (Kds) to consider if they are robustly derived and fit ... The focus of this review are SKB reports R-10-28 and TR-10-07 which describe the available site specific data and the subsequent derivation of CR and Kd values respectively for application in human assessment...
