Corrosion behavior for Alloy 690 and Alloy 800 tubes in simulated primary water
Corrosion Science, 2013Abstract Corrosion behavior for Alloy 690 and Alloy 800 in simulated primary water is studied by open-circuit potential (OCP) measurement, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. Rise of pressure and temperature lead to negative shift of corrosion potential for both Alloy 690 and Alloy 800. EIS results show that

Development of U-Bending Technology for Alloy 690 Tubes
Volume 1: Plant Operations, Maintenance, Engineering, Modifications, Life Cycle, and Balance of Plant; Component Reliability and Materials Issues; Steam Generator Technology Applications and Innovatio, 2012Steam generator installed with heat-transfer tubes (HTT) is an enormous heat exchanger that uses heat energy derived from a reactor to generate steam. The steam drains into turbine generator of an nuclear power plant, and plays an important role in producing electric power in nuclear power plant.

We show that enhanced stress corrosion cracking (SCC) initiation in cold-rolled Alloy 690 with decreasing strain rate is related to the rate of short-range ordering (SRO) but not to the time-dependent corrosion process. Evidence for SRO is provided by aging tests on cold-rolled Alloy 690 at 623 K and 693 K (350 °C and 420 °C), respectively, which ...

Pitting corrosion of Alloy 690 in thiosulfate-containing chloride solutions
Journal of Nuclear Materials, 2000Abstract The effects of thiosulfate ion and solution pH on pitting corrosion of Alloy 690 in chloride solution were explored. Potentiodynamic polarization measurements were conducted to evaluate pitting corrosion susceptibility of Alloy 690 in these environments.

Characterization of SCC Initiation Precursors in Cold-Worked Alloy 690
CORROSION 2017, 2017Abstract Although highly cold-worked UNS N06690 has been shown to be susceptible to stress corrosion crack growth in pressurized water reactor primary water, it is unclear whether stress corrosion cracking initiation occurs under constant load test conditions.

Predicting Susceptibility to Intergranular Stress Corrosion Cracking of Alloy 690
Corrosion, 2000Susceptibility to intergranular attack (IGA) and intergranular stress corrosion cracking (IGSCC) of Alloy 690 (UNS N06690) was investigated using chemical etching, double-loop electrochemical potentiokinetic reactivation (DL-EPR), and slow strain rate tests.

Effect of Deformation and Orientation on SCC of Alloy 690
CORROSION 2009, 2009Abstract Alloy 690, of various microstructures and types of cold work, was tested in representative pressurized water reactor primary water at 340 and 360 °C. Intergranular cracking was observed on Alloy 690 at constant stress intensity factor (no cycling) and with “gentle” cyclic loading.
