2024:10 Computational analysis of high-burnup fuel rod behaviour in PWR large-break LOCA
models for the thermomechanical behaviour of nuclear fuel in events such as LOCA and RIA. The research projects have been based on evaluations of tests on nuclear fuel in Halden Reactor Project (HRP) and Studsvik ... interpretations of the tests, including the analysis of new phenomena such as fuel fragmentation and its impact on the damage process. In this research project, a newly developed version of FRAPTRAN has been...

2007:24 Safety Management in Non-Nuclear Contexts Examples from Swedish Railway Regulatory and Company Perspectives
describe important features of safety management and the results are modelled according to the systems perspective developed. These are definitions of safety management, the structure of the organizations, organizational ... and accident reporting, and measurement of safety. The results tentative themes derived from the railway industry could be used in a systems approach to safety management in the nuclear context. However...

2021:02 On Water Induced Sensitization of Ni (Fe,Cr) alloys towards Stress Corrosion Cracking in LWR Piping from 1st Principles Modelling
SSM perspective Background In Swedish Light Water Reactors (LWR), stress corrosion cracking of reactor components and welds occurs from time to time. As the nuclear power plants are ageing, it is essential ... induced sensitization. Natural cracking is a phenomenon that is difficult to predict and very hard to study since it occurs suddenly and often unexpectedly. In order to study the crack initiation and growth...

2016:04 Uncertainty assessment of the SCANAIR V_7_5 computer program in analyses of BWR reactivity initiated accidents
In this work, we assess uncertainties that can be expected in computational analyses of boiling water reactor reactivity initiated accidents with the SCANAIR V_7_5 computer program. The work is intended ... intended to supplement a similar uncertainty assessment, focussed on pressurized water reactor accidents, which is currently being organized as an international benchmark exercise by the OECD Nuclear Energy...

2017:29 Evaluation of the simulation software CIVA for qualification purpose
studies. SSM has supported university research in the area for many years and, among other things, in the development of a software for ultrasound modeling. In addition, the accredited NDE laboratories are ... commercially most successful software in simulation of NDT situations. The program according to the supplier can handle different materials, geometries, cladding and anisotropy in arbitrary symmetry and orientation...

2011:26 The influence of temperature and fluid pressure on the fracture network evolution around deposition holes of a KBS-3V concept at Forsmark, Sweden
In preparation for the review of SKB’s license application for disposal of spent nuclear fuel, SSM is conducting studies to evaluate the performance of the multi-barrier principle on which the KBS-3 concept ... embedded in clay. Thus, the rock, the clay and the copper canister are acting as barriers in order to retard the possibility of spent fuel to escape the repository and reach the biosphere. During a very long...

2009:31 A Review of the Decommissioning Costs of the Ranstad Site
main objective of this study has been to review the future cost to decommission and dismantling the industrial area at the site of the old uranium mine at Ranstad in Sweden. Analyses of some detailed comparative ... information have been used in the context of preliminary “bench-marking” studies. The estimated costs for decommissioning of the old uranium mine in Ranstad have been compared with actual costs from other...

2013:09 An Application of the Functional Resonance Analysis Method (FRAM) to Risk Assessment of Organisational Change
The objective of this study was to demonstrate an alternative approach to risk assessment of organisational changes, based on the principles of resilience engineering. The approach in question was the ... (FRAM). Whereas established approaches focus on risks coming from failure or malfunctioning of components, alone or in combination, resilience engineering focuses on the common functions and processes that...

2015:38 Evaluation of fatigue in austenitic stainless steel pipe components
Transferability of experimental results obtained for smooth test specimens under constant amplitude loading to realistic components subjected to variable amplitude loading is an important issue in the design ... design against fatigue. There is a lack of experimental fatigue data for austenitic steel components and the present study is an important contribution to fill this gap. Objective The present study is aimed...
