This paper will discuss the various aspects surrounding the reliability and
performance of nuclear generating equipment and structures in light of corrosion
considerations. Corrosion failure mechanisms will be discussed for underground
plant piping. Case histories will be presented demonstrating corrosion and failure
problems and methods of implementing corrosion control procedures such as
protective coatings, cathodic protection (CP), water treatment, and material selection.
Key words: galvanic corrosion, corrosion management, hydrophobic, ground grid,
electrochemically corrosive environment, cathodic protection, protective coating,
current requirement, impressed current, sacrificial anode, deep anode ground bed,
indirect assessment methods, dielectric couplings, solid state decoupling device,
surface anode bed, coating pin hole or holiday, current density, ferrous sulphate injection.
