RISNonidealized Surface to Through Wall Crack Transition Model for Axial Cracks in Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have shown that a subcritical surface crack, due to primary water stress corrosion cracking (PWSCC), can transition to a throughwall crack (TWC) with significant differences between the inner diameter (ID) ...
Predicting the Impact of CRDM Thermal Sleeve Flange Wear in Westinghouse Pressurized Water Reactors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Dec. 2017, a four-loop 1300 MW Electricite de France (EdF) plant in France, Belleville Unit 2, experienced a complete wear through and separation of one of their thermal sleeves at a rodded control rod drive mechanism ...
Surface to Through-Wall Crack Transition Model for Circumferential Cracks in Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, finite element (FE) analyses were performed to update and also extend the applicable ranges of the existing KI and crack-opening displacement (COD) solutions for nonidealized through-wall cracks (TWCs). Then, ...
