Question

________ energy is obtained by the fission reaction of an isotope of uranium in a nuclear reactor.

• A. Thermal
• B. Nuclear
• C. Mechanical
• D. Electrical

Answer 1

The correct option is B Nuclear

$\bullet$ Nuclear energy is obtained by the fission reaction of an isotope of uranium in a nuclear reactor.

$\bullet$ In this process a heavy nucleus splits into smaller fragments, which emits neutrons and photons.
$\bullet$ The emitted neutrons collide with uranium-235 nucleus and cause new fission reactions resulting to a chain reaction.

$\bullet$ A large amount of nuclear energy is released during this process.
