Nuclear reactions occur when two nuclei or a nucleus and subatomic particle collide, producing different nuclides. There are two main types of nuclear reactions: fission and fusion. Fission reactions like those of U-235 release energy through neutron-induced chain reactions. Fusion reactions like that of deuterium and tritium have potential to provide future energy. Nuclear energy is mainly used to generate electricity but also has military, medical, and agricultural applications. It reduces greenhouse gas emissions compared to fossil fuels but nuclear fuels are non-renewable and accidents could release hazardous radioactive materials.

3. Nuclear Reaction:
A nuclear reaction is semantically considered to be the
process in which two nuclei, or else a nucleus of an atom
and a subatomic particle(such as a proton, neutron, or high
energyelectron) from outside the atom, collide to produce
one or more nuclides that are different from the nuclide(s)
that began the process.

4. Types of Nuclear Reactions:
• Fission Reactions
Typical and well-known neutron-induced fission reactions are:
235U (n, 3 n) fission products
These reactions release energy. The released neutrons induce
further reactions, causing contineous chain reactions.

6. • Fusion Reactions:
The fusion reaction of deuterium and tritium
is particularly interesting because of its
potential of providing energy for the future.

8. Uses of Nuclear Energy:
 Mainly used in generation of Electricity
 Military applications
 Nuclear Weapons
 Nuclear Medicines
 Food and Agriculture

11. Advantage of Nuclear Energy:
 The generation of electricity through nuclear energy
reduces the amount of energy generated from fossil
fuels (coal and oil).
 Less use of fossil fuels means lowering green house
gas emmisions (CO2 and others)
 The cost of Nuclear fuel (overall uranium) is 20% of the
cost of energy generated

12. Disadvantage of Nuclear Energy:
Like fossil fuels , nuclear fuels are non-renewable
energy resources .
If there is an accident , large amounts of radioactive
material could be released into the environment
Nuclear waste remains radioactive and is hazardous to
health for thousands of years
