Respuesta :
Correct answer is B
Explanation:
Control rods in Nuclear reactor:
During nuclear reaction when a heavy nucleus break up into two light nuclei that time neutron are release and these neutrons further break up other nucleus which release more neutrons which lead to a chain reaction. the nuclear reaction is kept from going critical by keeping the rate of reaction safe by using control rods. Controls rods absorb excess neutrons, keeping them from causing too many uranium atoms to split too quickly.
We see that controlled rods take in extra neutrons, keeping them from imposing too many uranium atoms to split up too quickly.
Option D is correct
How are nuclear reactions are kept from going critical?
Generally, at the nuclear response when a heavy nucleus spoils up into two mild nuclei, at that time neutrons are released, this process is repeated in progression and this launches additional neutrons which direct to a chain reaction.
Therefore, Controls rods take in extra neutrons, preserving them from inflicting too many uranium atoms to break up too quickly.
Option D is correct
