... ABSTRACT Hydrogen peroxide (H 2 O 2 ) is the most important oxidant to determine the corrosive environment of boiling water reactors (BWRs). Since H 2 O 2 is unstable at high temperature and electrochemical measurement in high purity water is difficult, H 2 O 2 polarization characteristics...

... and exposed to high temperature, high purity water at 360°C under constant load conditions. Specimens were also ring loaded to a K level of approximately 35 MPaÖm and exposed to high temperature high purity water at 338°C. SCC was observed in every specimen test with the exception of the 304L specimen cold...

... observed after several tens of thousands of hours at 300°C. The effect of thermal aging on mechanical properties, including tensile, toughness, fatigue and static crack growth has been investigated at room temperature and in 288°C high purity water simulating BWR operating conditions. The measurement...

... purity solution compared to the sulfate solutions. On these alloys, M3O4 formed in low dissolved oxygen solutions while a M2O3 film formed in high dissolved oxygen, similar to what has been observed in high purity water. Alloy 600 in the PWR experiments was polarized below an electrochemical potential...

... ABSTRACT The polarization behavior of the redox reactions of hydrogen (H 2 ), oxygen (O 2 ), and hydrogen peroxide (H 2 O 2 ) on 304 stainless steel (SS) in high temperature, high purity water was studied in order to determine the electrochemical kinetic constants, such as Tafel slopes...

... fracture mechanic specimens which were tested in high purity water in the temperature range of -1O°C to 320°C, depending on the alloy. Attention was directed towards region II behavior, where the crack propagation rate is independent of stress intensity but sensitive to test temperature. The experimental...
