1.The stages of the PUREX process are: Extraction, scrubbing, ionization Scrubbing, stripping, chelation Stripping, extraction, megapolation Extraction, scrubbing, stripping Absorption, ionization, fission Milling, conversion, enrichment a. C. d. e. f. g. one of the above 2.Nitric ac id is used in the PUREX process bec ause: It dissolves zirconium It dissolves fuel pellets It forms complex ions with uranium and plutonium a and b above b and c above none of the above a. d. e. f. 3. ,but Pure metallic uranium as a fuel has the advantage that it is disadvantage that it has the a. Anhydrous, sublimes b. Dense in U atoms, reacts with air and water c. Supercritical in the eutectic region, mixes with TBP d. Valuable, discolors readily e. A solid, dissociates in water f. Porous, high in saturated fat g. None of the above Solution purex is achemical method which is used to purify the nuclear reactors and nuclea weapons. purex stands for plutonium uranium redox extraction. by using this method seperate uranium and plutonoum. 1) the process are extraction , scrubbing, stripping. answer is (d) 2) the fuel is first dissolved in nitric acid at suitable concentraction(7m) and add tributyl phosphate is added ,folloewd liquid-liquid extraction process. it forms complex ions of uranium and plutonium. so the answer is (c) 3) i cannot find the answer.
