Abstract

Different FE models and programs were used to study the load of a RPV with an assumed partial circumferential crack in the near-core circumferential weld seam as a result of a mixing transient with temporal variation of coolant temperature in the axial and circumferential directions. Results tallied well with crack loads calculated by elasto-plastic FE analyses. Comparative calculations were performed involving simplified thermo-mechanical load assumptions, while assuming rotational-symmetric or strip-wise cooling at a RPV featuring assumed circumferential cracks of different depths and geometries.
