Purex 无盐试剂在流程中的应用研究进展 Title:ResearchProgressoftheApplicationofSalt-Free ReagentsinthePurexProcess Abstract: ThePurex(PlutoniumUraniumExtraction)processisawidely usedmethodforextractingplutoniumanduraniumfromspent nuclearfuel.ThetraditionalPurexprocessinvolvestheuseof variousreagents,includingsalts,whichintroducecomplexitiesin wastetreatmentandposechallengesintermsofnuclearsafety.In recentyears,therehasbeengrowinginterestinthedevelopment ofsalt-freereagentsasalternativestoovercometheselimitations. Thispaperprovidesanoverviewoftheresearchprogressmadein theapplicationofsalt-freereagentsinthePurexprocess.The potentialbenefitsandchallengesassociatedwiththeir implementationarediscussed. 1.Introduction: ThePurexprocessisanimportanttechniqueforthe separationandrecoveryofplutoniumanduraniumfromspent nuclearfuel.However,thepresenceofsaltsintheprocessposes challengesinwastetreatmentanddisposal.Salt-freereagents offerapromisingsolutiontoreducecomplexitiesandimprovethe efficiencyandsafetyofthePurexprocess. 2.AdvantagesandChallengesofSalt-FreeReagents: 2.1Advantages: -Simplifiedwastetreatment:Theabsenceofsaltsinthe processreducesthevolumeandcomplexityofwastegenerated duringthePurexprocess. -Enhancednuclearsafety:Salt-freereagentsreducetherisks associatedwiththehandlinganddisposalofradioactivewaste, improvingtheoverallsafetyoftheprocess. -Environmentalbenefits:Byeliminatingorreducingtheuse ofsalts,theenvironmentalimpactofthePurexprocessis mitigated,leadingtoamoresustainableapproach. 2.2Challenges:
