Optical Fiber Demodulation System with High Performance for Assessing Fretting Damage of Steam Generator Tubes

Sensors, 2018
In order to access the fretting damage of the steam generator tube (SGT), a fast fiber Fabry-Perot (F-P) non-scanning correlation demodulation system based on a super luminescent light emitting diode (SLED) was performed. By demodulating the light signal

Key Findings from the Artist Project on Aerosol Retention in a Dry Steam Generator

Nuclear Engineering and Technology, 2016
A steam generator tube rupture (SGTR) event with a stuck-open safety relief valve constitutes one of the most serious accident sequences in pressurized water reactors (PWRs) because it may create an open path for radioactive aerosol release into the ...

A 3D model to solve U-tube steam generator secondary side thermal-hydraulics with coupled primary-to-secondary side heat transfer

, 2020
The U-tubes of steam generators (SG) are concerned by vibration issues. The vibration behavior is driven by the local secondary flow (velocity, void fraction, two-phase pattern).

Evaluation of target-wastage in consideration of sodium-water reaction environment formed on the periphery of an adjacent tube in steam generator of sodium-cooled fast reactor

Nihon Kikai Gakkai ronbunshu, 2018
Wastage on adjacent tubes (target-wastage) arise from water/steam leak in steam generators of sodium-cooled fast reactors (sodium-water reaction). Target-wastage is likely to be caused by liquid droplet impingement erosion (LDI) and Na-Fe composite ...

Simulation of tube rupture in steam generator and transient analysis of VVER-1200 using PCTRAN

Energy Procedia, 2019
The objective of this paper is to present and analyze the results of simulated steam generator tube rupture (SGTR) accident in VVER-1200 Nuclear Reactor in PCTRAN. In simulating the accident, 100% of one full tube rupture has been considered.

Fretting wear damage mechanism of Inconel 690 alloy tube in nuclear power plant

Cailiao gongcheng
The steam generator is subjected to the action of high temperature and high-pressure steam， and the flow induced vibration phenomenon of its heat transfer tube is caused by the secondary lateral flow.

Flow visualization study at the interface of alternating pitch tube bundles in a model helical coil steam generator using particle image velocimetry

International Journal of Heat and Mass Transfer, 2018
A simplified Helical Coil Steam Generator (HCSG) model was constructed to study the flow on the shell side of rod bundles that coil against one another, using a 12-degree single rod bundle interface.
