چکیده

The materials of the article consider design characteristics horizontal steam generators PGV-1000 for WWER NPPs. NPP generator, in particular is a specific heat exchange unit. This unit, together with nuclear reactor and turbine, one main equipment multi-circuit (double-circuit) turbine generator produces working using dissipated from core by cooling medium sent to surface generator. generators, connecting contours coolant substance, equally belong each them. heat-absorbing substance (water, steam). type pressurized water reactors produce dry saturated steam. requirement maintain high purity due transfer surfaces such made austenitic stainless steel electropolished surfaces. do not allow boil core, so temperature at outlet (at inlet generator) always lower than saturation corresponding pressure circuit. Underheating (approximately 25 ÷ 30 °С) guarantees exclusion vaporization even most loaded channels. modern as various modifications provide technical economic performance units WWER-1000 maintainability, which allows extend service life domestic

A 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....

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 ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Fault Diagnosis for Steam-flow Exciting Vibration of Ultra Supercritical 1000 MW Steam Turbine

With the increase in thermal power capacity, ultra supercritical units have become the mainstream of power industry. At the same time, with the improvement of the steam parameters and the lengthening of shafting, the production of steam flow excited vibration is frequent in the ultra supercritical units, which may seriously affect the reliability of the unit. This paper has taken steam flow exc...
