What is nuclear fission? Explain with an example. Write the equation of the nuclear reaction involved.
Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei).The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a large amount of energy.
E.g., When uranium-235 atoms are bombarded with slow moving neutrons, the heavy uranium nucleus breaks up to produce two medium-weighted atoms and 3 neutrons, with the emission of tremendous amount of energy.
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?
