Reliability of Steam Generator Tubes With Axial Cracks
Journal of Pressure Vessel Technology, 1996An approach for estimating the failure probability of tubes containing through-wall axial cracks has already been proposed by the authors. It is based on probabilistic fracture mechanics and accounts for scatter in tube geometry and material properties, scatter in residual and operational stresses responsible for crack propagation, and characteristics ...

Vibration Damping of Stabilized Steam-Generator Tubes
Volume 4: Fluid Structure Interaction, 2005The integrity of steam-generator tubes is an important aspect of the long-term reliable operation of nuclear power plants. In situations where a tube is judged to be at risk, it must be either plugged, or removed, or reliably stabilized in some manner to avoid excessive motion of the tube due to flow-induced vibration.

Development of stabilizers for steam generator tube repair
Nuclear Engineering and Design, 1987Abstract Fluidelastic stability, turbulence-induced and vortex-induced vibration analysis of different types of stabilizers for repairing steam generator tubes are presented. The performances of the different designs are compared with that of a common basis — the virgin tube.

Caustic Cracking of Steam Generator Tube Materials
CORROSION 1976, 1976Failures of Inconel-600 steam generator tubes by caustic induced stress corrosion cracking have occurred in pressurized water reactors around the world.1,2 These failures have occurred in plants which used coordinated phosphate control of the secondary chemistry,3 in those which used an all volatile treatment,4 and in those which were in transition ...

Ginna Steam Generator Tube Rupture
1984At 9:25 a. m. on January 25, 1982, a single steam generator tube ruptured in the “B” steam generator at the R. E. Ginna Nuclear Power Plant. Prior to the incident, the plant, a two-loop Westinghouse design, had been operating at full power with no indications of primary to secondary leakage.

In-Situ Pressure Testing of Steam Generator Tubes
10th International Conference on Nuclear Engineering, Volume 1, 2002The anatomist John Hunter said, “But why think? Why not try the experiment?” His words are applicable to in-situ pressure testing as a means of performing condition monitoring of steam generator tubes. Other methods of performing condition monitoring include the application of theoretical burst and leakage equations (deterministic methods ...

A Contribution to Assessment of Steam Generator Tubes Integrity
2005Three-dimensional linear and non-linear finite element analyses have been carried out to determine the stress intensity factors, the J-integral and the plastic limit loads for external axial semi-elliptical surface cracks in VVER steam generator tubes under internal pressure.
