Investigation on reverse flow characteristics in U-tubes under two-phase natural circulation

open access: yesNuclear Engineering and Technology, 2020
The vertically inverted U-tube steam generator (UTSG) is widely used in the pressurized water reactor (PWR). The reverse flow behavior generally exists in some U-tubes of a steam generator (SG) under both single- and two-phase natural circulations (NCs).

The Fretting Wear Characteristics of CrN and TiN Coating on Steam Generator Tube [PDF]

open access: yes, 2010
A steam generator tube of a nuclear power plant is damaged by a fretting phenomenon caused by flow induced vibrations (FIV). In this work, the surface of the tube was coated with CrN or TiN as a measure to improve performance of the fretting wear ...
