Sensitivity study of the pretest analysis of the NESC-1 spinning cylinder experiment
This report presents results from the pretest analysis of the NESC-1 spinning cylinder. The cylinder has an internal diameter of 1045 mm, a wall thickness of 175 mm and a length of 1296 mm. An internal surface breaking crack with depth of 73 mm and length of 205 mm subjected to a thermal shock is studied here. 3D elastic-plastic finite element calculations, considering the crack-tip constraint, are employed in the analysis. Also performed are sensitivity studies to demonstrate how different affecting parameters such as the specific modelling of the cladding HAZ and the cladding residual stresses impact the crack driving force. From the sensitivity studies, it is observed that uncertainties due to different assumptions in the analysis influence the assessment results less than uncertainties in the brittle fracture toughness data of the materials.
