Service water systems are a critical part of the infrastructure of nuclear plants.
Corrosion has been shown to be the predominant degradation mechanism for service water
piping. Because of the diversity of water sources (seawater, brackish water, and various fresh
waters), piping materials (bare carbon steel, coated or lined carbon steel, stainless steels, and
non-ferrous metals), and service water system designs, a guideline for service water piping
requires a set of concise rules, rather than a proscriptive chemical “recipe” for the system to
achieve its design life.
