2014:19 Evaluation of the Halden IFA-650 loss-of-coolant accident experiments 5, 6 and 7
The analytical tools, which are fuel rod computer codes, that Quantum Technologies AB use and develop, contain models of several of the phenomena that are acting on the nuclear fuel (cladding temperature, fission gas driven pressure, strain and stress in the cladding, rod rupture, etc.) and how the separate effects interact in the complex integrated manner. The codes are under constant...

2014:56 Seismic design and analysis of safety-related nuclear structures in Sweden
The report presents the historical development of the seismic design for the U.S., France and Sweden with special focus on issues related to severe earthquakes beyond the design basis as well as important aspects concerning the design basis ground motions for the Swedish nuclear facilities. The report provides recommendations on a revised model for seismic hazard assessments, on minimum...

2014:20 An evaluation of high-temperature creep of zirconium alloys: data versus models
In this report Dr Massih presents correlations for creep in different phases of zirconium alloys and also presents a general solution to the difficulty of accurately describing the material properties in phase transition for several zirconium alloys. Based upon superplasticity relations, models are adapted to fit with experimental data for materials in transition regions. The creep models are...

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...

2014:48 Technical Note, Independent assessment of groundwater sulphide content in the long-te
Groundwater sulphide content is a key factor in the determination of canister lifetimes because of its role in corrosion of copper. SKB has based the canister lifetime analysis on a distribution of measured sulphide concentrations which are assumed to apply throughout the long-term analysis period. The distribution is based on expert judgement in the selection of samples that are regarded as...

2014:50 Technical Note, A Study of Availability of Fuel Data for Sweden’s Spent Nuclear Fuel
The study covers all types spent fuel planned to be placed in the final repository. It was carried out by selecting a sample of spent fuel and investigating the information available at the Nuclear Power Plants (NPP’s) in Sweden, the Central interim storage facility (Clab) and Studsvik. The results indicate that the required data is available and can be obtained for fuel unloaded after 1980.

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...

2014:53 Översyn av systemet med diagnostiska referensnivåer
Strålsäkerhetsmyndighetens mål för medicinsk röntgendiagnostik är att röntgenundersökningar ska vara berättigade och optimerade. Ett sätt att stimulera verksamhetsutövarna till att optimera sina röntgenundersökningar är det nationella systemet med diagnostiska standarddoser och referensnivåer. Sedan systemet infördes...

2014:51 Report from SSM’s scientific council on ionizing radiation within oncology, 2013. MR in radiotherapy - an important step towards personalised treatment?
Imaging is important for radiotherapy and the development of new imaging modalities is closely linked to the evolution of modern radiotherapy. The implementation of magnetic resonance imaging (MRI) in modern radiotherapy holds great promise for the future but the scientific council emphasizes that it must be carefully monitored in order to minimize the introduction of new risks, violating...
