Characterization of phases in ‘crud’ from boiling-water reactors by transmission electron microscopy

Electrochemistry Studies of Semiconductor Properties of Structure Materials in the Nuclear Power Plants by Zinc Injection Technique

“…In another hand, the corrosion rate of metal [9], besides stress corrosion [10] and pitting corrosion [11,12], is highly related to the behavior of oxide films. Dawn E. Janney, et al [13] studied deposit of reactor fuel bundle in 2 boiling water reactors in which zinc injection technique was adopted, and willemite (Zn 2 SiO 4 ) was observed. Y. J. Kim [14] reported that the Fe 2 O 3 in outer layer of passive film of 304 stainless steel, which formed in high temperature water with 5ppb Zn 2+ and 15ppb Cu 2+ addition, turned into Fe 3 O 4 /ZnFe 2 O 4 and Cr enriched in inner layer.…”

The Semiconductor Character and Corrosion Resistance of Passive Film of 316L Stainless Steel (SS) and Nickel Alloy 800 Formed in Zinc Contained High-Temperature and High-Pressure Water

“…In the other hand, the corrosion rate of metal [9], besides stress corrosion [10] and pitting corrosion [11,12], was highly related to the semiconductor behavior of passive film. Many previous investigations [12][13][14][15][16] have reported that the corrosion resistance of stainless steels depended on the composition, structure and thickness of the passive film.…”

“…Dawn E. Janney, et al [15] studied deposit of reactor fuel bundle in boiling water reactors in which zinc injection technique were adopted. D. Shintani et al [16] investigated that the film was a double-layer structure consisting of a Fe oxide-rich outer layer and a Cr oxide-rich inner layer.…”
