  1. 1. INTRODUCTION Thisprojectreportis an efficiencyanalysisof the PaloVerde NuclearPowerPlantlocatedin Tonopah,Arizona.Thisreportwill include:  Specificoutlineof plantdetailsandcharacteristics  Comparisontoothernuclearpowerplantsinthe UnitedStates  Analysisof electricaloutputandcostof production Thisplantruns a PWR (pressurizedwaterreactor) tertiarycycle,withthe primarycycle beingthe side linkedtothe heatfromthe reactor,the secondaryside runningalarge turbine generator, and the tertiarycycle runninga smallerturbine generatoraswell.Allof these cyclesare connectedbya seriesof heatexchangers,eachincorrespondinglydescendingtemperatures. The processI will be analyzingisthe secondarycycle.The secondarycycle consistsmainlyof a turbine connectedtoa generator,acondenser,afeedpump,anda heatexchanger(toreceive heatfrom the primaryside).The condenserandheatexchangerare consideredtobe completelyefficient(all heatistransferred,none islost)andthe turbine andpumpare consideredtoinitiallybe isentropic(efficienciesusedtocalculate actual workdone).Below you will findthe othercharacteristicsof the powerplantthatI believe make itbetterthananyother competingnuclearplantinthe UnitedStates,orthe world. PLANT DETAILS AND CHARACTERISTICS There are several keycharacteristicsof thispowerplantthatmake itstand out fromthe rest of the nuclearplantsinthe U.S., some of those being:  Size – one of the largestnuclearpowerfacilitiesinproductiontoday,generatingnearly 4GW of energy,20%higherthanany otherplantin the U.S.  Efficiency –rumoredto have near70% planttotal efficiency  Record-LowRadiation –Duringthe plant’slastoutage cycle,the average radiation exposure wasonly19 (beatingpreviousrecordof 20)  PWR – Waterin the primaryreactor line (nuclearreactorside) ispressurizedabove 2000psi to preventthe waterfromboiling,thuscreatingamore stable cycle  Turbine-Generators –PaloVerde housesthree of the world’slargestturbinegenerators, each producingnearly 1.3GW of energyonaverage (the powerplanthasthree units). Aside fromthe abovementionedcharacteristicsof thisnuclearplant,there isalsoone final designdetail thatis of greatimportance:the location.PaloVerde isone of the veryfew power plantsthat isnot locatednexttoa large bodyof water,itbeinginthe middle of Arizona.Palo UNIVERSITY OF MINNESOTA DULUTH To: Dr. Bill Pedersen From: TylerLenzen Date: 12/11/2013 Re: ThermodynamicsProject
  2. 2. Verde evaporatesthe waterfromsewage treatmentplantsfromnearbycitiesandtownsand usesthat condensedwatertoprovide waterforthe secondaryline of the nuclearpowercycle. PaloVerde isthe onlypowerplantinthe worldto use thistechnology. COMPARISON In the previousparagraph,Ibrieflytoucheduponthe factthatPaloVerde useswater evaporatedfromlocal sewage treatmentplantsasitsmainsource of water.Inadditiontothis, PaloVerde hasmanyadditional environmental benefitssuchas:  PollutionDisplacement –Since the beginningof itsoperationin1968, the powerplant has displacedmore than: o 2.8 milliontonsof sulfurdioxide o 503 milliontonsof carbondioxide,and o 1.6 milliontonsof nitrogenoxides  No Emissions –The powerplantemitsnofumesaside fromsteam, because itdoesnot use any fossil fuelstogenerate electricity.  Abundance of Fuel –Studieshave shownthatthere isenoughuraniuminthe earth todayto keepnuclearpowergoingforhundredsof yearswithouthavingtofindanother fuel source   NuclearContainment –Itis statedthat the containmentshieldingof the generating stationisover4 feetthickandcan withstandthe force of a jetaircraftat full speed. It isthese reasonsabove thatI believethispowerplantbeatsoutnearlyanyothertype of generatingplant.Inthe nextsection,Iwill analyze the electrical outputof the turbine generatorsandcalculate the efficiencyof the generators. ANALYSIS Appendedtothisreport isthe analysisof the efficiencyandpoweroutputof the generating station.Since the stationhasthree differentunits,Iwill assume the poweroutputforeachunit is1.3GW inmy calculationswhichare appendedtothisreport. Afterthe analysis,Iconcludedthat: Capitalgained W'net  costenergy hoursyear 5.782 10 8  $ Thispowerplantmakesupwardsof $578200000 a year (before all otherconsiderations),or578 milliondollars.Iamsure that there are a significantlylarge amountof costsassociatedwiththe restof thispowerplant,butI have neglectedtheseforthisanalysis. In conclusion,inthisanalysisIhave inferredthatthispowerplantmakesasignificantamountof money,andalsoadds a large amountof powertothe grid of Americathat otherwise would have to be addedby coal or natural gas,both of whichemitgasesthat are harmful to the environmentandthe image of powerproductionfacilities.Ibelieve thatnuclearpowerstations like thisone have agreat thinggoing,andI also believe thatwe shouldinvestheavilyinthemas theyare the powerof the future.
