NUCLEAR FISSION : 

NUCLEAR FISSION U235 + n → fission + 2 or 3 n + 200MeV When a neutron strikes an atom of uranium, the uranium splits into two lighter atoms and releases heat simultaneously. Fission of heavy elements can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments

NUCLEAR CHAIN REACTIONS : 

NUCLEAR CHAIN REACTIONS This nucleus in turn produces neutrons, and the process repeats. If the process is controlled it is used for nuclear power or if uncontrolled it is used for nuclear weapons A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus.

NUCLEAR POWER PLANT WORKING : 

NUCLEAR POWER PLANT WORKING Nuclear fission creates heat inside the reactor Heat transfers to steam generator where steam forms. Steam turns turbine and generator which converts steam into electricity Steam routs to condenser. Cool water removes excess heat, condensing steam into water Water then pumps back to steam generator for reuse

Nuclear power in India : 

Nuclear power in India Nuclear power is the fourth-largest source of electricity in India after thermal, hydro and renewable sources of electricity. India has 17 nuclear power plants in operation generating 4,120 MW while 6 other are under construction and are expected to generate an additional 3,160 MW.

ADVANTAGES : 

ADVANTAGES Nuclear energy has no typical pollutants or greenhouse gasses One million times as much energy in one pound of Uranium as in one pound of coal. It is possible to generate a high amount of electrical energy in one single plant. Use the nuclear energy in the war.

DISADVANTAGES : 

DISADVANTAGES The problem of radioactive waste is still an unsolved one. High risks: It is technically impossible to build a plant with 100% security. Uranium is a scarce resource, its supply is estimated to last only for the next 30 to 60 years depending on the actual demand.
