Corrosion

2. The S in IGSCC
4. Reduction takes place and this electrode
5. Corrosion characterized by a chemical or Electro-chemical reaction that occurs uniformly over a surface
7. Red Brown Ferric Oxide (rust)
8. limited to approximately 2.2 ppm in PWR reactor coolant to minimize risk of caustic attack of the zirconium alloy fuel cladding
11. ________________ induced corrosion (MIC)
14. Corrosion that is increased when material is exposed to rapidly moving turbulent fluid
15. form of localized corrosion where the rate of attack is much greater at certain areas on the surface than others.
17. occurs when electrochemically dissimilar metals are metallically connected and exposed to a conductive environment (electrolytic solution).
18. used as an irritant to prevent zebra muscle colonization
19. Generally attributed to a tenacious oxide film on the metal surface, which separates the base metal from the environment

1. Corrosion which occurs within an area which is shielded from the bulk environment
3. Oxidation takes place at this electrode
4. promotes transgranular stress corrosion cracking (TGSCC) of annealed stainless steel, plus pitting and crevice corrosion.
6. Gaining of electrons
9. The most detrimental ion relative to environmentally assisted cracking of materials (stainless steel) used in the BWR environment
10. The oxidation potential of a Standard Hydrogen Electrode
12. a measure of the gross level of ions or dissolved ‘solids’.
13. Loss of electrons
16. For carbon steel systems corrosion rates will __________ when dissolved oxygen falls below 20 ppb.
