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 ... zirconium alloys (Ziracaloy-2 and Zircaloy-4) and upgraded to fit for Zr1%Nb materials. The adaptations are successful since a good agreement between experimental data and model computation has been reached...

2014:19 Evaluation of the Halden IFA-650 loss-of-coolant accident experiments 5, 6 and 7
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 ... cladding, rod rupture, etc.) and how the separate effects interact in the complex integrated manner. The codes are under constant development and need to be compared with actual tests. In this report simulations...

2014:17 Technical Note, Assessment of radiological effects on non-human biota –Main Review Phase
This report presents a review of SKBs assessment of the long-term radiological effects on plants and animals of a deep geological repository as described in SKB report TR-10-08. The SKB report is one of ... each element of the assessment was considered separately. The appropriateness of the SKB approach and the effect of any justifiable alternatives were evaluated. A key protection goal of the assessment...

2014:11 Technical Note, Radionuclide Solubility Limits in SKB’s Safety Case
part of the main phase of SSM’s license application review. The project involved review of reports and independent modelling studies on issues related to the potential solubility of radionuclides in waters ... radionuclide solubility limits in a series of reports and papers that have been produced over several years. The model is scientifically based and founded on the principles of chemical thermodynamics.

2014:09 Further Development of the Core Simulator CORE SIM: Extension to coupled capabilities for BWRs
The developed tool is fully MatLab based and requires a set of input data from a commercial static core simulator. The driving perturbation can be specified both as a perturbation in thermo-hydraulic parameters ... distribution of the noise in coolant density, pressure, enthalpy, inlet velocity, fuel temperature and neutron flux is obtained. In this work, some results of the noise simulations, performed for the case...
