The recirculating cooling water (RCW) system has served the Paducah Gaseous Diffusion Plant (PGDP) since 1951. Over the years, there have been changes to the system: cooling tower additions, cooling tower replacements, pump upgrades and the installation of a cathodic protection system. However, the basic system of headers and piping remains the same as the original construction. This paper will illustrate the problems experienced in a 40+-year-old piping system and the methods used to transform failing expansion joints, valves and piping ranging from 12 and 60 inch diameter into a reliable operating facility.
