U238 will undergo fission by

A. High energy (fast) neutrons alone

B. Low energy (slow) neutrons alone

C. Either fast or slow neutrons

D. Medium energy neutrons

Answer: Option A

Solution(By Examveda Team)

U238 will undergo fission by high energy (fast) neutrons alone.
The much more abundant uranium-238 does not undergo fission and therefore cannot be used as a fuel for nuclear reactors. However, if uranium-238 is bombarded with neutrons it absorbs a neutron and is transformed into uranium-239.
