The Effect of Clamping Force on the Wear Behavior of a Steam Generator Tube

Applied Sciences, 2022
Anti-vibration bars (AVBs) are essential components of a steam generator (SG) and are used to prevent steam generator tubes (SGTs) from vibrating intensely because of flow-induced vibration.

Procedure of Active Residual Heat Removal after Emergency Shutdown of High-Temperature-Gas-Cooled Reactor

Science and Technology of Nuclear Installations, 2014
After emergency shutdown of high-temperature-gas-cooled reactor, the residual heat of the reactor core should be removed. As the natural circulation process spends too long period of time to be utilized, an active residual heat removal procedure is ...

Physicochemical Reinforcement Unlocks Sterilization‐Stable Anisotropic Hydrogels for Cell‐Compatible Mock Arteries

Advanced Healthcare Materials, EarlyView.
ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)

Fiber Fabry-Perot Force Sensor with Small Volume and High Performance for Assessing Fretting Damage of Steam Generator Tubes

Sensors, 2017
Measuring the radial collision force between the steam generator tube (SGT) and the tube support plate (TSP) is essential to assess the fretting damage of the SGT. In order to measure the radial collision force, a novel miniaturized force sensor based on
