2007:21 On tentative decommissioning cost analysis with specific authentic cost calculations with the application of the Omega code on a case linked to the Intermediate storage facility for spent fuel in Sweden
The aim of this applied study has been to demonstrate how a cost calculation is done in a systematic way. The framework of the project has been limited to older nuclear installations in Sweden. Furthermore, it may be envisaged that the process of making regular estimates of all the parameters is crucial in preparatory phases of decommissioning and dismantling processes. A secondary aim of the...

2023:11 Study of degradation of spent fuel’s structural material and core components under long-term wet storage
SSM perspective Background Sweden is managing the spent nuclear fuel and core components from its commercial nuclear reactors with a national strategic plan. The fuel and core components are initially ... initially stored at the reactor site. After an on-site storage period to comply with transportation limits on decay heat and radiation, these materials are shipped to the Clab (Central Interim Storage Facility...

2010:29 SKI:s och SSI:s synpunkter på SKB:s FoU/Fud-program 1986-2007
frågeställningar i samband med granskningarna. Myndigheternas målsättning har varit att påverka SKB:s utformning av Fud-programmen, bland annat med syfte att framtida slutförvarsansökningar ska kunna uppfylla ... kärnbränsle första kvartalet 2011 och därför är det nu angeläget för Strålsäkerhetsmyndigheten (SSM) att följa upp SKB:s hantering av viktiga synpunkter på Fud-programmen. En utgångspunkt för denna uppföljning...

2014:05 Technical Note, Assessment of flows to deposition holes – Main Review Phase
SKB’s conceptual model for flow through the fractured rock at Forsmark is based on a division between highly fractured deformation zones (described in terms of deterministic geometry), and the more sparsely ... these assumptions on flows to deposition holes is judged to be minor, compared with uncertainties in the model for the more sparsely fractured rock. This assessment focuses mainly on the statistical model...

2014:59 Technical Note, Relation between earthquake magnitude, fracture length and fracture shear displacement in the KBS-3 repository at Forsmark – Main Review Phase
spent nuclear fuel at the Forsmark site. Two sources of threat are: i) events due to thermal loading on the rock mass by the heat from canisters with spent nuclear fuel, and ii) seismic events, i.e. earthquakes ... the shear displacement on rock fractures induced either by the eff ect of thermal loading, or by an earthquake at a nearby deformation zone, or by the combination of the two. In SKB’s safety assessment SR-Site...

99:10 Verification and Validation of HumanFactors Issues in Control RoomDesign and Upgrades
power plant's lifetime. This has human factors implications, especially if the central control room is involved. Human factors work may therefore be required. There is an extensive literature on human factors ... factors itself, but not so much on how it is verified and validated. Therefore, HRP and the Swedish Nuclear Power Inspectorate (SKI) commissioned a study. The objective was to review the literature and establish...

2011:30 A fatigue analysis including environmental effects for a pipe system in a Swedish BWR
The effect of the environment on fatigue design has been the subject of intense study in USA, Japan and elsewhere. Several reports indicate a potentially large influence of the environment, leading to ... proposal of entirely new analysis procedures. SSM has in an earlier project sponsored research to evaluate the technical basis for these proposals, see SSM Research Report 2011:04. In the current report...
