97-13: PGDP Enhances Plant RCW ReliabilityThe 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

In addition it presents a mathematical method which can be used to predict the performance of a cooling tower which has a fill height and fill air travel

examined by electrochemical techniques and by microscopic examination

in wet-dry mode and zero visible plume in dry mode

Building owners and engineers should test water samples for Legionella from cooling systems

The initial performance test indicated a major tower deficiency

The studies and conclusions reported in this paper are the resuits of the author's own work

The paper reviews existing methods to indicate testing accuracy and attempts to establish a detailed method application to cooling tower testing

No one would expect a structure almost constantly drenched with large volumes of water to be considered a fire hazard

Advances in online testing and online instrumentation allowing quick decisions about the quality of these waters

Further power reductions may be realized as a result of lower cascade flow losses and improved airfoil insensitivity to roughness effects

galvanized cooling towers that have not been properly treated at start-up may experience rapid formation of a soft
