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...

2007:12 Development of a constitutive model for the plastic deformation and creep of copper and its use in the estimate of the creep life of the copper canister
The copper-iron canister for disposal of nuclear waste in the Swedish Programme has a design life exceeding 100,000 years. Whilst the operating temperature and operating stress are modest, the very long design life does require that the likely creep performance of the canister should be investigated. Many studies have been carried out by SKB but these have all involved very short duration...

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...

2007:15 Evaluation of the FRAPTRAN -1.3 Computer Cod
The FRAPTRAN-1.3 computer code has been evaluated regarding its applicability, modelling capability, user friendliness, source code structure and supporting experimental database. The code is intended for thermo-mechanical analyses of light water reactor nuclear fuel rods under reactor power and coolant transients, such as overpower transients, reactivity initiated accidents (RIA),...

2007:35 Urananrikning med laser och plasmaseparation - en analys med fokus på exportkontroll
Den nu resulterande rapporten berör kortfattat några generella principer för laseranrikning, både separation av atomärt uran – AVLIS - och separation av uran i molekylär form – MLIS. Vidare berörs mycket översiktligt några andra metoder inklusive plasmaseparation. Dessutom nämns vilken utrustning som kan komma ifråga, indikatorer på laseranrikning,...

2007:13 Elektrokemiska aspekter på korrosion i svenska reaktorinneslutningar
Samtliga svenska reaktorinneslutningar är konstruerade av spännarmerad betong. Ingjutningsgods i betong skyddas normalt mot korrosion genom att porvattnet i betongen är starkt alkaliskt. Denna miljö medför att stål passiveras. Under speciella omständigheter kan korrosion ändå uppstå. Viss uppföljning av korrosionsbilden i reaktorinneslutningarna...

2007:06 Probabilistic Safety Goals - Phase 1 -Status and Experiences in Sweden and Finland
Based on a series of interviews and on literature reviews as well as on a limited interna- tional over-view, the project has described the history and current status of safety goals in Sweden and Finland. A number of issues were discussed more in detail, including the status of the safety goals in view of the fact that they are often exceeded, strategies for handling violations of safety...

2007:27 Kompetensöverföring på svenska kärnkraftverk i samband med pensionsavgångar
Rapporten visar att ett av Sveriges tre kärnkraftverk har ett program för kompetensöverföring. På de två som saknar program efterfrågas mer struktur inom området, även om man redan nu arbetar med mentorer eller handledare. Genomgående är upplevelsen av bristen på resurser för överrekrytering och tiden till att överföra.

2007:04 Link Between RI-ISI and Inspection Qualification: Relationship between Defect Detection Rate and Margin of Detection
A relationship has been established between defect detection ratio and margin of detection based on blind trails. The results are based on a rather small amount of data produced by personnel from one inspection laboratory but give us indications of how signal to noise ratio is possible to relate to the probability of detection (POD) used in RI-ISI models. The relationship need to be developed...

2007:14 Review of experimental data for modelling LWR fuel cladding behaviour under loss of coolant accident conditions
This project has contributed to the research goal of giving a basis for SKIs supervision by means of evaluating experimental data and modelling the nuclear fuel cladding during a design base accident. The project has also contributed to the research goal to develop the competence about licensing of fuel at high burnup, which is an important safety issue. The results are useful as such, but...
