1.0 NEEDFORCIRCULATING

WATERSYSTEMMODIFICATION Fullflowoperation oftheCirculating WaterSystem(CWS)forStLucieUnit1wasattempted inJanuaryof1976.Atthattime,theoceanportionofthesystemconsisted oftwo12footdiameterintakepipelines andone12footdischarge pipeline. Separateintakeanddischarge canalsonlandconveyedtheoceancoolingwatertoandfromtheplant~Duringinitialoperation, veryhighwaterlevelsoccurredinthedischarge canal,causingsomeflowoveranemergency spillway'ecause ofthis,thesystemwasshutdown. Subsequent testingofCWpumpsperformance inearlyFebruaryindicated thattheywerepumpingabout15percentabovethedesignflow.However,throttling thepumpswiththedischarge valvestothedesignflowstillresultedinhigherthanexpectedwaterlevelinthedischarge canalandhydraulic headlosses inexcessofthoseexpectedinbothintakeanddischarge pipelines. Theseconditions weredetermined tobetheresultofhigherthanexpectedoceantides,andtheformation ofmarinegrowthonthepipewall,asdescribed below.Adiver'sinspection ofthepipelines revealedtheformation ofmarinegrowthonthepipewall(severalinchesthickontheintakepipelines, aboutoneinchthickonthedischarge pipeline) alongtheentirelengthofthesepipelines. Testsperformed todetermine thehydraulic characteristics ofeachpipelineindicated thatthehydraulic headlosses intheoceanpipelines werehigh,andthatthepipelinefrictionfactor(Darcy-Wiesbach 'f')wasdetermined tobe0.030fortheintakepipelineand0.024forthedischarge

pipeline, ascomparedwithacleaxrpipe h.~)f frictionfactorof0.015orless.Thesehigherfrictionfactorswerecausedbymarinegrowthonthepipewallandaddedapproximately threeftandtwoftofhydraulic headlosstotheintakeanddischarge pipelines, respectively, representing 50percentand30percentincreaseintotalheadlosses forthesepipelines.

Todemonstrate thatthemarinegrowthseriously affectedthehydraulic frictionfactor,thedischarge pipelinewascleanedinSeptember of1976torestorethefrictionfactorto0.016.Areduction ofabouttwofeetofheadlosswasrealized. Additionally, periodicmonitoring ofthehydraulic performance oftheoceanpipelines wasinitiated todetermine changesinthefrictionfactor.Theresultsofthismonitoring areshowninFigure1.0-1.Fromthemonitoring program,itwasconcluded thatmarinegrowthonthepipewallwouldrequiretreatment eitherbyperiodiccleaningofthepipelines, orbysometypeofcontrolorbyphysicalmodification ofthesystem.Sincethetwointakepipelines weredesignedtosupplywaterforStLucieUnits1and2,nooperating problemwasexperienced forStLucieUnit1ontheintakeside.However,whenStLucieUnit2becomesoperational in1983thecombinedeffectsofheadlosses, asindicated intestssimulating twounitoperation, willadversely affectplantoperations inthatexcessive headlosses throughtheintakepipelines couldreducetheintakecanalwaterlevelsuchthatminimumpunpsubmergence requirements could ~~notbemet~Similarly, excessive headlosses intheoceandischarge pipelinewouldresultinhighwaterlevelsinthedischarge canalandpossiblespillwayoverflowtothemangroves northofthecanal.Finally,thecombinedheadlossincreases wouldreducethevolumeofcoolingwaterpumpedthroughtheplantsuchthatplanttemperature risewouldexceedtheoriginal24Fmaximumandplantefficiency wouldbereduced.In1978,thedischarge canaldikesandtheoverflowspillwaywereraisedtoaccommodate higherwaterlevelsinthedischarge canal.Additionally, aperiodicpipecleaningroutinewasintitated forthe12footdiameteroceandischarge pipeline. Finally,theStLucieUnit2oceandischarge

pipeline, whichhasbeenconstructed, wasincreased indiametertoallowformarinegrowthaccumulations.
