Question

What must happen to uranium before it can be used as a fuel source?

A. No changes are necessary.

B. Stable U-235 must be enriched with 3% radioactive U-238.

C. Stable U-238 must be enriched with 3% radioactive U-235.

D. Unstable U-235 must be enriched with 5% U-238 to stabilize it.​

Answer 1

Answer:

D

Explanation:

Before it can be used in a reactor for electricity generation, however, it must undergo a series of processes to produce a useable fuel. For most of the world's reactors, the next step in making the fuel is to convert the uranium oxide into a gas, uranium hexafluoride (UF6), which enables it to be enriched.

Answer 2

Unstable U-235 must be enriched with 5% U-238 to stabilize it.​ Hence, option D is correct.

What is radioactive?

Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei into atomic nuclei to form more energetically stable atomic nuclei.
