(Mar. 23) 74th Academic Lunch Seminar of Sino - French Institute of Nuclear Engineering and Technology

Last updated :2018-03-20

Topic: The state of the art of Tube Support Plate (TSP) clogging phenomenon in PWR steam generators
Speaker: Dr. Guangze YANG
Time: 12:40–14:00, Friday, March 23, 2018
Venue: F309, teaching building, Zhuhai Campus, SYSU
Organizer: Sino-French Institute of Nuclear Engineering and Technology, SYSU
Language: English

Abstract:

The steam generator is an essential component in PWR, which allows the heat exchange between the primary and secondary circuits. After 15-20 years of operation, an obstruction by deposits of flow holes between Tube Support Plate (TSP) and primary tubes is observed, called TSP clogging. This phenomenon may lead to catastrophic consequences for nuclear power plant operation and radiation protection. TSP clogging is a complicated phenomenon, involving various fields such as thermohydraulics, chemistry and metallic materials. Nowadays, this phenomenon remains poorly studied. To understand the formation mechanism of TSP clogging and to further find suitable remedies, this talk is aimed to thoroughly provide a state of the art of this phenomenon, based on nuclear power plant feedbacks, previous works in literature and speaker’s Ph.D. study conducted in CEA in France. A guideline for future investigations of TSP clogging will also be proposed.

About the speaker:
Dr. Guangze YANG, Associate research fellow at IFCEN, SYSU. Dr. Yang obtained his master and French engineer degrees from both Chimie ParisTech (Paris) and INSTN (Saclay) in 2014, and Ph.D. degree from Paris VI University (Paris) in 2017. All the research works were carried out in CEA Cadarache (Saint-Paul-les-Durance, France) during his Ph.D.. His main research interests include nuclear materials, corrosion, ageing problems in PWR steam generators (TSP clogging, fouling, sludge etc.) and irradiation effects on materials.
