RISA Reassessment of PWR Pressure Vessel Integrity During Overcooling Accidents, Considering 3-D Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A continuing analysis of the pressurized-thermal-shock problem associated with PWR postulated overcooling accidents indicates that the previously accepted degree of conservatism in the fracture-mechanics ...
A Probabilistic Approach to the Evaluation of the PTS Issue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integrated probabilistic approach for the evaluation of the pressurized-thermal-shock (PTS) issue was developed at the Oak Ridge National Laboratory (ORNL) at the request of the Nuclear ...
Fracture Mechanics Data Deduced From Thermal-Shock and Related Experiments With LWR Pressure Vessel Material
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal-shock experiments with steel cylinders have been conducted at ORNL to investigate the behavior of long axial inner-surface flaws during loading conditions similar to those imposed by a ...
