Nuclear utilities must insure that service water systems are available for situations ranging from continuous cooling to standby for critical emergency cooling. The service water systems in most plants operating today were built with carbon steel piping and many of these systems have incurred high maintenance costs. These costs have been attributed to various forms of corrosion under stagnant water conditions, fouling, and blockage due to coating delamination with critical consequences in emergency situations. The UNS S32205 duplex stainless steel has properties that are ideally suited for service water piping applications. The first application of S32205 for service water piping was installed at Duke Power's Catawba Nuclear Station in a system where Type 304 stainless and carbon steel proved unsatisfactory. This paper reports on the service history of installed S32205 piping after 500 days of service. The inside diameter pipe surfaces exhibit minimal deposit buildup and no general or localized corrosion. Likewise, welds are free of corrosion indicating that welds as well as the base metal resist the aggressive cooling water environment. The S32205 grade has recently been approved by ASME for Section 111, Class 2 or 3 construction and is more cost effective than many of the more highly alloyed stainless steels. With the recent ASME Code approval, the nuclear utility industry now has another piping material option for safety, as well as, non-safety related service water piping applications.
