- 2. Used as an irritant to prevent zebra muscle colonization
- 8. Corrosion characterized by a chemical or Electro-chemical reaction that occurs uniformly over a surface
- 9. Gaining of electrons
- 11. Loss of electrons
- 13. A measure of the gross level of ions or dissolved ‘solids’.
- 15. Reduction takes place and this electrode
- 16. The most detrimental ion relative to environmentally assisted cracking of materials (stainless steel) used in the BWR environment
- 19. Red Brown Ferric Oxide (rust)
Down
- 1. The oxidation potential of a Standard Hydrogen Electrode
- 3. Generally attributed to a tenacious oxide film on the metal surface, which separates the base metal from the environment
- 4. ________________ induced corrosion (MIC)
- 5. Form of localized corrosion where the rate of attack is much greater at certain areas on the surface than others.
- 6. Occurs when electrochemically dissimilar metals are metallically connected and exposed to a conductive environment (electrolytic solution).
- 7. Corrosion which occurs within an area which is shielded from the bulk environment
- 10. For carbon steel systems corrosion rates will __________ when dissolved oxygen falls below 20 ppb.
- 12. Oxidation takes place at this electrode
- 14. The S in IGSCC
- 17. Limited to approximately 2.2 ppm in PWR reactor coolant to minimize risk of caustic attack of the zirconium alloy fuel cladding
- 18. Promotes transgranular stress corrosion cracking (TGSCC) of annealed stainless steel, plus pitting and crevice corrosion.
- 20. Corrosion that is increased when material is exposed to rapidly moving turbulent fluid
