(The American Society of Mechanical Engineers (ASME), 2022)In typical leak-before-break (LBB) analyses in the nuclear industry, the uncracked piping normal operating forces and moments are applied in a cracked-pipe analytical procedure to determine normal leakage, and the combined ... -
Normalized Ratcheting Diagram Under Sinusoidal Vibration Waves
(The American Society of Mechanical Engineers (ASME), 2022)Ratcheting is a progressive incremental inelastic deformation or strain which can occur in a component that is subjected to variations of mechanical stress, thermal stress, or both. This study concentrated on the ratcheting ... -
A Method for Monitoring Vibrational Fatigue of Structure and Components
(The American Society of Mechanical Engineers (ASME), 2022)A vibrational fatigue monitoring system has been developed by Framatome to assess, in real-time, the evolution of industrial structures, systems and components lifetime expectancy. Its originality comes from the fact that ... -
J Predictions for Defective Pipe Elbows Via the Reference Stress Method
(The American Society of Mechanical Engineers (ASME), 2022)In R6, the J-based failure assessment diagram (FAD) method is used in the fracture assessment and is underpinned by the reference stress J scheme. Therefore, an assessment using the R6 FAD method is equivalent to a J ... -
Deterministic and Probabilistic Evaluations of Structures and Components Credited for Seismic Design Extension Conditions
(The American Society of Mechanical Engineers (ASME), 2022)There is “high confidence” in the ability of the structures, systems, and components (SSCs) of nuclear power plants (NPPs) to perform as designed for design basis accidents (DBAs). For design extension conditions (DECs), ... -
Fatigue Damage Management According to Performance-Based Maintenance Concept
(The American Society of Mechanical Engineers (ASME), 2021)A maintenance concept of performance-based maintenance (PBM) has been proposed by the current author. According to the PBM concept, inspection results are considered in determining the next inspection schedule. In this ... -
