    Abstract: This investigation is to present a verification study of probabilistic fracture mechanics (PFM) analysis code for a reactor pressure vessel (RPV) during pressurized thermal shock (PTS). The probabilistic fracture mechanics code FAVOR, developed by Oak Ridge National Laboratory, is used to calculate the conditional probabilities of crack initiation ... Show More

    Abstract: Throughout the homologation process, especially in Germany, the torsional load acting on the wheelset due to drive train oscillations must be evaluated. The maximum values of these dynamic torsional moments are strongly influenced by the adhesion conditions in the wheel/rail contact and the slip velocity range between wheel and rail due to drive co...
