An analysis on the consequences of a severe accident initiated steam generator tube rupture
Nuclear Engineering and Design, 2019An analysis on the thermal hydraulic behavior, core damage progression and radiological releases of a steam generator tube rupture event initiated by a station black out event for APR1400 is provided in this paper.

Integrity of VVER steam generator tubes
Theoretical and Applied Fracture Mechanics, 1995Abstract The eddy-current inspection is applied to Vitkovice to non-destructive testing of the steam generator tubes. The steam generator tube specimens, 16 mm by 1.5 mm, are made of AISI 321 steel with stress corrosion cracks. They were tested by the single-frequency eddy current inspection method.

Steam generator tube vibration tests
Nuclear Engineering and Design, 1985Abstract The buildup of magnetite in the steam generators of some pressurized water reactors had led operators to propose chemical cleaning to remove this product. In some cases, the volume of magnetite formed by the corrosion of the carbon steel has been sufficient to cause “denting” or reduction of the outer diameter of the tubes where they pass ...

Flaw analysis in steam generator tubes
International Journal of Pressure Vessels and Piping, 1986Abstract This paper presents the flaw assessment programme undertaken in France for PWR steam generator tubes affected by stress corrosion cracking. Failure criteria were deduced from burst tests on various crack configurations. Stresses and critical crack sizes were estimated for all operating conditions.

Damping of Steam Generator Tubes
Flow-Induced Vibration, 2003The flow-induced vibration (FIV) analysis is one of the most critical evaluations needed to ensure long-term operation of steam generator. Original design hardware is usually based on experience and testing. Performance changes, such as an increase in power with increased feedwater flow, or tube repairs including plugs, stabilizers, and sleeves are ...

Factors Affecting Steam Generator Tube Bow
Volume 3: Design and Analysis, 2013One of the challenges in straight shell-and-tube Steam Generator design is to avoid the tube to tube wear that can arise during operation due to higher than anticipated compressive tube loads and the resulting tube bow that can occur. Tube bow becomes significant when the compressive load in the tube exceeds its critical buckling capacity.
