Expansion joints are installed on the sodium pipelines of fast reactor power stations to absorb the displacement for thermal compensation.This can reduce the difficulty in the layout of pipelines, supports and hangers, effectively shorten the length of sodium pipelines and reduce the number of spring supports and hangers, thus realizing the compact
A Multistage Physics-Informed Neural Network for Fault Detection in Regulating Valves of Nuclear Power Plants
In Nuclear Power Plants (NPPs), online condition monitoring and the fault detection of structures, systems and components (SSCs) can aid in guaranteeing safe operation.The use of data-driven methods for these tasks is limited by the requirement of physically consistent outcomes, particularly in safety-critical systems.Considering the importance of

Rotating Behavior Observation of Cavitation in Inducer with Suction Axi-Asymmetrical Plate
The attachment of inducer in front of main impeller is a powerful method to improve cavitation performance.In operating condition at partial flow rate and extremely low suction pressure, cavitation surge oscillation occurs and the stable operating range becomes narrower.It has been found from previous experimental study of authors that the cavitati
