Question:

Which one of the following is used to remove most of plutonium from spent nuclear fuel?

  1. $\mathrm{ClF}_{3}$

  2. $\mathrm{O}_{2} \mathrm{~F}_{2}$

  3. $\mathrm{I}_{2} \mathrm{O}_{5}$

  4. $\mathrm{BrO}_{3}$


Correct Option: , 2

Solution:

$\mathrm{O}_{2} \mathrm{~F}_{2}$ oxidises plutonium to $\mathrm{PuF}_{6}$ and the reaction is used in removing plutonium as $\mathrm{PuF}_{6}$ from spent nuclear fuel.
