2007:23 On Safety Management, A Frame of Reference for Studies of Safety Management with Examples From Non-Nuclear Contexts of Relevance for Nuclear Safety
The authors present the theoretical framework. There they also discuss the pros of using the system perspective to build a useful frame of reference of safety management using non- nuclear organizations; this as a way to create models useful for the nuclear power industry but based on general understanding of the concept of safety management. The chosen organizations are used extensively to...

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...

2017:13 Monte Carlo patient-specific pre-treatment QA system for volumetric modulated arc therapy
Background The clinical use of volumetric modulated arc therapy (VMAT) has augmented rapidly since it became commercially available. As a result, the need for comprehensive quality assurance (QA) has increased. Current practices in Sweden normally compare the delivered dose with the planned dose based on measurements with different methods, for instance: portal dosimetry, point dose...

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...

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...

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...

2011:02 The Back-End of the Nuclear Fuel Cycle in Sweden, Considerations for safeguards and data handling
The report is a compilation report consisting of three papers. A safeguards approach for the planned encapsulation facility and the operating final repository is presented in paper 1. Special considerations concerning safeguards for the final disposal process have been discussed and incorporated into the approach. Paper 2 defines the spent fuel data that must be secured, for safeguards...

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...

2015:15 Användning av låg- och höganrikat uran – en studie från ett icke-spridningsperspektiv
Höganrikat uran definieras som uran med en anrikning av 235U på minst 20 %. Att minska eller helt eliminera det civila användandet av hoöanrikat uran är ett viktigt led i internationellt icke-spridningsarbete. Till skillnad från plutonium är höganrikat uran inte en biprodukt utan framställs för ett specifikt ändamål. Detta innebär att...

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...
