Nuclear fission

Question 1

Nuclear fission

Answer 1

large nuclei break up into form smaller nuclei and releases energy

Question 2

Daughter nuclei

Answer 2

store a lot of kinetic energy because they are moving at high speeds

Question 3

Chain reaction

Answer 3

neutrons continue to travel and be absorbed by new nuclei

Question 4

Uranium 235

Answer 4

splits into two daughter nuclei as soon as it absorbs a neutron and two or more neutrons are released

Question 5

How is energy transferred in fission

Answer 5

by heating

Question 6

what happens when the chain reaction of uranium 235 continues

Answer 6

causes an atomic bomb

Question 7

control rods

Answer 7

contains elements which absorb neutrons

Question 8

Fuel rods

Answer 8

As fissions occurs, neutrons leave the fuel rods at high speeds

Question 9

Moderator

Answer 9

fuel rods are places in here to slow down the movement of the neutrons which are released by the fuel rods

Question 10

how are the control rods placed in a nuclear reactor

Answer 10

they are placed in between the fuel rods in the moderator, the further in the control rods are, the more neutrons are absorbed

Question 11

How does the nuclear reactor generate electricity

Answer 11

Energy released is transferred to a coolant
A hot coolant is pumped to a heat exchanger to make steam which drives a turbine to generate electricity
