Question

If each fission reaction in a nuclear reactor emits three neutrons, how many neutrons are produced from three fission reactions?
one
three
six
nine

Answer 1

I thinking the answer is nine

Answer 2

Answer : The correct option is, Nine.

Explanation :

Nuclear fission : It is defined as the splitting of bigger nuclei into two smaller nuclei. During this process neutrons and some energy also released.

In nuclear reactor, neutron hits the uranium nucleus, the uranium nucleus splits into two nuclei and three neutrons. These three neutrons further hit the uranium nucleus and the uranium nucleus split into two nuclei and these 3 neutrons produces 9 neutrons.

The reaction for nuclear fission is,

$^{235}_{92}U+^1_0n\rightarrow ^{89}_{36}Kr+^{144}_{56}Ba+3^1_0n$

As, Each nuclear fission reaction produces 3 neutrons

So, three nuclear fission reaction produces 9 neutrons
