In case of nuclear energy, the objective of enrichment process is

The correct answer is: Increasing the concentration of fissile 235U.

Important Points

In the context of nuclear energy and the enrichment process, the main objective is to increase the concentration of fissile uranium-235 (235U) isotope in the uranium fuel.

• Natural uranium consists of mostly non-fissile uranium-238 (238U) and a small percentage of fissile uranium-235 (235U).
• For most nuclear reactors, a higher concentration of uranium-235 is required for sustained nuclear fission reactions, which produce energy.
• The enrichment process involves separating and increasing the proportion of uranium-235 in the uranium fuel to make it suitable for use in nuclear reactors.

thus the correct answer is Increasing the concentration of fissile 235U

Additional Information Nuclear reactor:

• It is a device in which a nuclear reaction is initiated, maintained, and controlled.
• It works on the principle of controlled chain reaction and provides energy at a constant rate.
