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

(A) $BrO_{3}$
(B) $O_{2} F_{2}$ ✓ Correct
(C) $I_{2} O_{5}$
(D) $ClF_{3}$

Answer: (B)

Solution

Spent nuclear fuel is treated with dioxygen difluoride,

O_{2} F_{2}

, a very strong fluorinating and oxidising agent. It converts plutonium into volatile plutonium hexafluoride,

Pu F_{6}

, which is distilled off and so separated from the bulk of the fuel. The reagent used to remove most of the plutonium from spent nuclear fuel is

O_{2} F_{2}
