2011:12 Analysis of Barrier Performance: Modelling of Copper corrosion scenarios with and without buffer erosion
(intersecting deposition holes) and local SRB activity all contributes to an uneven corrosion profile on the canister. This is not caused by a true localized corrosion phenomenon but rather by what might ... formulation of SRB activity suggests only a moderate influence on copper corrosion. Steven J. Benbow, Peter C. Robinson and Sarah P. Watson SSM English The purpose of this project was to develop a numerical...

2013:27 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures
349-06 code open up today for a more detailed analysis where the beneficial impact of reinforcement on anchor capacity can be taken into account. How this analysis can be done is, however, not explicitly ... sufficient reinforcement is present. The objective of the project is to study the effect of reinforcement on the concrete breakout capacity of cast in headed bolts in concrete structures by numerical simulations...

2013:24 Modelling of nuclear fuel cladding under loss-of-coolant accident conditions
The results are compared with experimental data on cladding rupture strain, temperature and pressure. The effects of heating rate and rod internal pressure on the rupture strain are evaluated by systematic ... alloy, for which no definite constitutive relation is yet available. Tero Manngård and Ali R. Massih SSM English We present a unified model for calculation of zirconium alloy fuel cladding rupture during...

2012:11 Issues in the corrosion of copper in a Swedish high level nuclear waste repository
knowledge in the area of copper corrosion in the planned repository environment and obtain information on how copper corrosion evolves during the assessment period of 100 000 years. The equilibrium chemical ... as a function of temperature has been calculated by use of a thermodynamics code called GEMS. Based on the results, the following sulphide species (S2-, HS-, H2S, HS22-, and S22-) are predicted to be present...
