RISInvestigation on Constraint Effect of a Reactor Pressure Vessel Subjected to Pressurized Thermal Shocks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The integrity of a reactor pressure vessel (RPV) related to pressurized thermal shocks (PTSs) has been extensively studied. This paper introduces the method of using fracture mechanics for the integrity analysis of a RPV ...
Probabilistic Pressurized Thermal Shocks Analyses for a Reactor Pressure Vessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Both deterministic and probabilistic methods are used to assess the integrity of a reactor pressure vessel (RPV) subjected to pressurized thermal shocks (PTSs). The FAVOR code is applied to calculate the probabilities for ...
Probabilistic Pressurized Thermal Shock Analysis for a Reactor Pressure Vessel Considering Plume Cooling Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The inner surface of a reactor pressure vessel (RPV) is assumed to be subjected to pressurized thermal shocks (PTSs) caused by the injection of emergency cooling water. The downstream is not homogeneous but typically in a ...
Constraint Assessment for Specimens Tested Under Uniaxial and Biaxial Loading Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In structural integrity analysis of reactor pressure vessels (RPVs), a postulated shallow crack is subjected to biaxial far-field stresses. However, the fracture toughness Kc or Jc, which is an important material property ...
