Overview of Steam Generator Tube-Inspection Technology
Degradation of steam generator (SG) tubing due to both mechanical and corrosion modes has resulted in extensive repairs and replacement of SGs around the world. The variety of degradation modes challenges the integrity of SG tubing and, therefore, the stations’ reliability. Inspection and monitoring aimed at timely detection and characterization of the degradation is a key element for ensuring ...
متن کاملIntegrity and Integration Issues for Nano-Tube Based Interconnect Systems
As we continue miniaturization of circuits into nano-scale, interconnects have been recognized as the limiting factor for next generation of computing structures. To increase the density of integration many approaches have been proposed such as System on Chip (SoC), System in Package (SIP), and Networks on Chip (NoC)which all must address the interconnect issue address. Current approaches to So...
متن کاملA MEMS Steam Generator
Previous work [1] has shown that MEMS technology has significant potential to create more compact, higherperforming hardware for chemical oxygen iodine lasers (COIL). In COILs, the laser medium is a flowing gas that must be pumped through the system at high mass flow rates to ensure proper system operation. As a result, compact pumps with high pumping rates are a key element of the COIL system....
متن کاملParticulate Fouling and its Effect on U-Tube Steam Generator Thermal Performance
A multiple-node SIMULINK model of a U-tube steam generator (UTSG) has been developed so as to simulate the UTSG dynamics or responses to various defects, including fouling. UTSG responses to different events, such as reduced heat transfer area, change in heat transfer coefficient at different axial nodes, change in tube material conductivity, and the change of steam valve coefficients have been...
متن کاملDevelopment of a Robust Model-Based Water Level Controller for U-Tube Steam Generator
Government or any agency thereof. The views and opinions of authors expressed herein do not necessarily state or reflect those of the United States Government or any agency thereof. SUMMARY Poor control of steam generator water level of a nuclear power plant may lead to frequent nuclear reactor shutdowns. These shutdowns are more common at low power where the plant exhibits strong non-minimum p...
