Describe the working of a hydrogen bomb.
The hydrogen bomb consists of heavy isotopes of hydrogen called deuterium and tritium along with lithium-6. Atom bomb is used for the explosion of hydrogen bomb. While the atom bomb is exploded, since its fission reaction a lot of heat is produced which raises the temperature of deuterium and tritium to 107°C in a few microseconds. Then fusion reactions of deuterium and tritium take place which produces a tremendous amount of energy. This explodes the hydrogen bomb. Lithium-6 is used to produce more tritium needed for fusion.
The following questions are about the nuclear reactor of a power plant.
a) Which isotope of uranium produces the energy in the fuel rods?
b) Will the fuel rods last forever?
c) Is the energy produced by nuclear fission or nuclear fusion?
d) What is the purpose of using the graphite moderator ?
e) What is the function of boron rods in the nuclear reactor?
f) Why is liquid sodium (or carbon dioxide gas) pumped through the reactor?
