Dow HDPE water pipe for nuclear power plant

As this was to be the first ever use of HDPE in a safety-related water pipe system at a nuclear plant in North America, the team at Callaway had to create a material specification and related procedures from scratch. In the process, they underwent a change in mindset from focusing on what was available to specifying what was really needed. Most importantly, Callaway engineers began to work closely with members of the HDPE pipe value chain. These players included The Dow Chemical Co. (Dow) as the HDPE supplier, WL Plastics Corp. as the pipe manufacturer, and Independent Pipe Products Inc. for the manufacture of special pipe fittings. The consultant, Frank Schaaf, Jr. of Sterling Refrigeration Corp., was also instrumental in the work necessary to gain approvals from the NRC. Callaway team selected CONTINUUM DGDA-2492 Bimodal Polyethylene Resin from Dow as the raw material for its new ESW secondary water pipe system. According to the team at Callaway, this installation is a first important step toward HDPE becoming a preferred material for safety-related water pipe systems at nuclear power stations. AmerenUE is already planning to replace other buried piping with HDPE in other systems in 2009.
