RISApplication of Fracture Assessment Method Considering Constraint Effect to Ductile-Brittle Transition Temperature Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the long-term operation of nuclear power plants, evaluating the integrity of reactor pressure vessels (RPVs) against neutron irradiation has become increasingly important. In the context of pressurized thermal shock ...
Determination and Sensitivity Analysis of Target Flaw Sizes for Performance Demonstration of Cast Austenitic Stainless Steel Pipe by Probabilistic Fracture Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The material of primary coolant pipe of nuclear power plants is cast austenitic stainless steel (CASS), which has a coarse crystal structure and its anisotropy causes low permeability of ultrasonic waves and low detectability. ...
