2006:36 Mechanical Integrity of Canisters Using a Fracture Mechanics Approach
This report presents the methods and results of a research project for Swedish Nuclear Power Inspectorate (SKI) about numerical modeling of mechanical integrity of cast-iron canisters for the final disposal of spent nuclear fuel in Sweden, using combined boundary element (BEM) and finite element (FEM) methods The objectives of the project are: 1) to investigate the possibility of initiation...

2007:17 Spent Fuel Dissolution and Source Term Modelling in Safety Assessment
SKI is preparing to review the license applications being developed by the Swedish Nuclear Fuel and Waste Management Company (SKB) for a final repository for the geological disposal of spent nuclear fuel (SFL-2) in the year 2009. As part of its preparation, SKI is conducting a series of technical workshops on key aspects of the Engineered Barrier System (EBS) and spent fuel. This workshop...

2007:19 An Applied Study of Implementation of the Advanced Decommissioning Costing Methodology for Intermediate Storage Facility for Spent Fuel in Studsvik, Sweden with special emphasis to the application of the Omega code
The aim of this applied study has been to describe in a systematic way an appropriate methodological sequence for cost estimation of crucial parameters in decontamination and decommission processes. The work has been limited to older nuclear installations and facilities. Furthermore, it may be envisaged that the process of estimating the parameters of decommissioning is one of the main issues...

2007:30 Modelling the Interaction of Low pH Cements and Bentonite
Concrete and cement are used in constructions as well as in conditioning of waste inrepositories for radioactive waste. It is well known that in the hyperalkaline conditions (pH > 12) of standard cement pore fluids, there is potential for deleterious effects upon the host rock and other EBS materials, notably bentonite, in geological repositories. Low pH cements are beginning to be considered...

2018:08 Calculated radiological consequences of applying European clearance levels to scrap metal from the decommissioning of Swedish nuclear facilities
Background Many practices involving radioactive substances generate materials with potential or known radioactive contamination. Clearance of materials means a decision that such materials can be released from regulatory control and used or disposed of without restrictions from a radiation protection point of view. According to regulations issued by the SSM, such decisions must be based on...

2001:10 Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken 2000
Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken är gott. Säkerheten och strålskyddet upprätthölls under 2000 på en tillfredsställande nivå i förhållande till de säkerhets- och strålskyddskrav som ställs, vilka är jämförbara med de krav som är allmänt accepterade i jämförbara...

2000:15 Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken 1999
Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken under tillsyn av Statens kärnkraftinspektion (SKI) och Statens strålskyddsinstitut (SSI) är gott. Säkerheten och strålskyddet upprätthölls under 1999 på en tillfredsställande nivå i förhållande till de säkerhets- och strålskyddskrav som ställs...

2000:01 Statistisk analys av uppmätta tillväxthastigheter hos spänningskorrosionssprickor (IGSCC)
Sprickor vid interkristallin spänningskorrosion har utgjort ett allvarligt problem inom kärnkraftsindustrin världen över. Ansenliga resurser har fokuserats på försök att förstå mekanismerna bakom denna typ av korrosion och därmed skapa möjligheter att förebygga eller åtminstone lindra problemet. Spricktillväxthastigheten har...

99:10 Verification and Validation of HumanFactors Issues in Control RoomDesign and Upgrades
Systems, facilities and equipment are periodically updated during a 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 itself, but not so much on how it is verified and validated. Therefore, HRP and the Swedish Nuclear Power Inspectorate...
