2013:02 Forskningsreaktorer - en analys med fokus på icke-spridning och exportkontroll
Den nu resulterande rapporten berör kortfattat några olika typer av forskningsreaktorer liksom några av deras viktigaste användningsområden. Dessutom berörs reaktorernas användbarhet för plutoniumproduktion samt några indikationer på reaktordrift. Vi har valt att låta rapporten vara översiktlig utan att gå in på detaljer för...

2014:04 Global Non-proliferation ‘Clubs’ vs. the NPT
The study analyses the relationship between the Nuclear Non-Proliferation Treaty, NPT and various initiatives and institutions (‘clubs’) based outside the NPT framework, which aims to improve and strengthen the Treaty. The study identifies conflicts and possible synergies and proposes options for developing and improving the interaction between the NPT and ‘clubs’ in order to increase the...

2016:39 Recommended residual stress profiles for stainless steel pipe welds
Background The Swedish Radiation Safety Authority (SSM) and the Swedish nuclear power plant owners have financed Inspecta Technology in Sweden to analyze stainless steel pipe welds to obtain good estimations of weld residual stress (WRS) distributions. Detailed knowledge of the residual stress field in different types of welds is important since they can have substantial influence on...

2014:21 Effects of additives on uranium dioxide fuel behavior
This report will form a basis for the reviews that SSM does when the license holders applies for use of nuclear fuel with additives. The report is also intended as a reference to the models that Quantum Technologies AB has developed. The report and the models will be a valuable source of information for SSM and other parties when discussing the performance of doped fuel. Ali Massih SSM...

2013:01 Validation of Weld Residual Stress Modeling in the NRC International Round Robin Study
Weld residual stresses (WRS) have a large influence on the behavior of cracks growing under normal operation loads and on the leakage flow from a through-wall crack. Accurate prediction on weld residual stresses is important to make proper decisions when cracks in weld joints are detected. During the latest years, there has been a strong development in both analytical procedures to...

2011:06 Reliability Data Handbook for Piping Components in Nordic Nuclear Power Plants – R Book, Phase 2
The Nordic PSA Group (NPSAG) has undertaken to develop a piping reliability parameter handbook for use in risk-informed applications that involve the consideration of structural integrity of piping systems. The scope of the handbook is to establish high quality reliability parameters that account for the Nordic and worldwide service experience with safety-related and non-safety-related piping...

2011:05 Overview and Evaluation of the NESC Projects for Fracture Assessments of Nuclear Components
The Network for Evaluation of Structural Components (NESC) was started in 1993 and since then six different projects have been carried out. A seventh NESC-project is still in progress. The overall objective of these projects has been to study the reliability of the entire process of structural integrity assessment within an international framework. The network is coordinated by the European...

2010:47 Utveckling av programpaket för analys av termisk utmattning
I ett tidigare NESC-projekt (Network for Evaluating Structural Components – Thermal Fatigue) togs fram en Europeisk procedur för hantering av termisk utmattning. Den tidigare myndigheten Statens kärnkraftinspektion (SKI) var en av projektets finansiärer. Proceduren innehåller bl.a. utvärdering av en modell för analys av högcykelutmattning vid turbulent termisk...

2010:06 Upphandling inom kärnkraftsindustrin, kvalitet, säkerhet och beslutsfattande
Upphandling av tjänster eller annan inhyrd personal eller utrustning såsom byggnadsdelar, komponenter, system är att betrakta som en del av den kärntekniska verksamheten och ska därmed omfattas av ledningssystemet med tillhörande nödvändiga instruktioner (Strålsäkerhetsmyndighetens föreskrifter om säkerhet i kärntekniska anläggningar,...

2008:33 Risk-informed assessment of defence in depth, LOCA example
The methods that are used today in PSA are applicable for evaluating defence-in-depth levels 1 and 2. Failure data can be determined through: human reliability analysis, riskinformed in-service-inspection methodology, system reliability analysis and directly from plant specific failure data for the components. Many DID activities against LOCA are not explicitly modelled in typical...
