2005:41 Models for Fuel Rod Behaviour at High Burnup
Perspective Background During recent years a considerable amount of work has been performed on studying the behaviour of nuclear fuel at high burnup and to model it in computer codes. SKI has previously ... afore- mentioned processes. Grain growth kinetic modelling is briefly reviewed and pertinent data on grain growth of high burnup fuel obtained during power ramps in the Third Risø Fission Gas Release...

2021:10 Establishment and use of attention values in environmental fatigue assessments
SSM perspective Background As Swedish NPPs reach their original technical design life, re-assessment of the fatigue life of structural components is needed for safe long term operation (LTO). In these ... these re-assessments one must consider that new knowledge has shown that environmental effects on fatigue life must be considered. One common method to verify the fatigue life of structural components subjected...

2004:32 A Strain-based Clad Failure Criterion for Reactivity Initiated Accidents in Light Water Reactors
than previously estimated. At the beginning of 1995 SKI issued fuel and cladding failure limits based on available test data. It was envisaged at that time that the failure limits should be re-evaluated when ... joined the OECD-IRSN CABRI water loop project at the end of 2000. The purpose was to gain information on the failure threshold for nuclear fuel cladding as a function of burnup, especially for modern cladding...
