AProposaltoResearchtheStorageFacility

forSpentNuclearFuelatYuccaMountain

October1997

Introduction

Nuclearpowerplantsproducemorethan20percentoftheelectricityusedintheUnitedStates[Murray,1989].Unfortunately,nuclearfission,theprocessusedtocreatethislargeamountenergy,createssignificantamountsofhighlevelradioactivewaste.Morethan30,000metrictonsofnuclearwastehavearisenfromU.S.commercialreactorsaswellashighlevelnuclearweaponswaste,suchasuraniumandplutonium[Roush,1995].Becauseofthebuild-upofthiswaste,somepowerplantswillbeforcedtoshutdown.Toavoidlosinganimportantsourceofenergy,asafeandeconomicalplacetokeepthiswasteisnecessary.ThisdocumentproposesaliteraturereviewofwhetherYuccaMountainisasuitablesiteforanuclearwasterepository.Theproposedreviewwilldiscusstheeconomicalandenvironmentalaspectsofanationalstoragefacility.Thisproposalincludesmymethodsforgatheringinformation,ascheduleforcompietingthereview,andmyqualifications.

StatementofProblem

OnJanuary1,1998,theDepartmentofEnergy（DOE）mustacceptspentnuclearfuelfromcommercialplantsforpermanentstorage[Clark,1997].However,theDOEisundecidedonwheretoputthishighlevelradioactivewaste.YuccaMountain,IocatedinNevada,isaproposedsite.

TherearemanyquestionsregardingthesafetyoftheYuccaMountainwasterepository.ResearchersatLosAlamosNationalLaboratorydisagreeovertheIong-termsafetyoftheproposedhighlevelnuclearwastesitelocatedinNevada.In1994,CharlesBowman,aresearcheratLosAlamos,developedatheoryclaimingthatyearsofstoringwasteinthemountainmayactuallystartanuclearchainreactionandexplode,similartoanatomicbomb[Taubes,1995].ThestircausedbytheorysuggeststhatresearchershavenotexploredallsidesofthesafetyissueconcerningpotentiallyhazardoussituationsatYuccaMountain.

（1）explainthecriteriaforasuitablerepositoryofhigh-levelradioactivewaste;and

（2）determinewhetherYuccaMountainmeetsthesecriteria.

AccordingtotheDepartmentofEnergy（DOE）,arepositoryforhigh-levelradioactivewastemustmeetseveralcriteriaincludingsafety,location,andeconomics[Roush,1995].Safetyincludesnotonlytheeffectoftherepositoryonpeoplenearthesite,butalsopeoplealongthetransportationroutestothesite.InmyresearchIwillconsiderbothgroupsofpeople.Asfaraslocation,awastesitecannotbeinanareawithalargepopulationornearagroundwatersupply.Also,becauseoneofthemostsignificantfactorsindeterminingthelifespanofapossiblerepositoryishowlongthewastestoragecanisterswillremainintact,thewastesitemustbelocatedinadryclimatetoeliminatethemoisturethatcancausethewastecanisterstocorrode.Theeconomicsinvolvedin
