Engineers increase the concentration of uranium-235 atoms in nuclear fuelduring what process?A. Uranium-235 modificationB. Half-lifeC. Nuclear fuel modificationD. Enrichment

Respuesta :

Explanation:

The majority of nuclear reactors use the isotope uranium-235 as fuel; however, it is only a small part of the natural uranium mined. The concentration must be increased through a process called enrichment. Enrichment is the process of increasing the concentration of uranium-235 atoms in nuclear fuel.

Answer: D. Enrichment
