Question

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 None of the above a. c. d. e. f. g. 2. Nitric acid is used in the PUREX process because: a. It dissolves zirconium b.It dissolves fuel pellets c. It forms complex ions with uranium and plutoniunm d. a and b above e. b and c above f none of the above 3 State why it is necessary to change the valence of Pu in the second stage of the PUREX process 4. Write the structural formula: 2-chlorobutane

Explanation / Answer

1) PUREX : First stage involves the extraction to separate the irradiated fuel's ywo main components - Uranium and Plutonium -from a residue of fission products and minor actinides which are considered as waste.

Then the scrubbing process for the back extraction and then followed by stripping

Option d is the correct answer.
