Nuclear EngineeringPUREX is an acronym standing for Plutonium and Uranium recover by ExtractionProcess used to reprocess nuclear fuel in order to extract Uranium and Plutonium

PUREXDissolved in Nitric AcidDissolution of irradiated fuel in Aqueous nitric acid, Uranium and Plutonium are transferred to Organic phase by intensive mixing with organic solvent extraction

PUREXUranium extraction processSeparation of 99.9% Uranium and >95% of Technetium by the addition of acetohydroxamic acidAddition of AHA provide greater proliferation resistance

UREXAddition of Secondary agent n-octyl(phenyl)-N,N-diisobutyl arbamoylmethylphosphine oxide in combination with tributylphosphate, the PUREX process is turned in to TRUEX(Transuranic Extraction) process.To remove the transplutonium metals from waste

TRUEX(CMPOMOXMixed OxideBlend of plutonium and Uranium

MOXPyrometallurgical process(Nuclear reprocessing)Separating actinides element with actinide family

PYROProcessSpent fuel is melted, and mixed with molten saltElectric Current applied, actinide(cathode) while non-actinide waste remain in salt.Mixed Actinides produce by pyrometallic processing ca be used as Nuclear fuel as fissile or fertile

PYROHybrid process involving fluoride volatiliy and solvent extractionfluoride volatiliy-purify UPurex process-purify U and Pu mixtures

FLOUREXfluoride volatiliyPurified with decontaminator factor of 107 using NaF absorbers.
