Nuclear energy works through nuclear fission, where uranium-235 is split in a nuclear reactor, generating heat. This heat is used to boil water and create steam that powers generators to produce electricity. Key advantages are that it is an energy-dense source that produces reliable base-load power with low greenhouse gas emissions. Disadvantages include nuclear waste, decommissioning costs, and safety risks from meltdowns. Overall, nuclear energy provides society with cheap, efficient electricity while creating jobs through global interest in the technology.

3. Introduction
•Uranium was discovered in 1789 by Martin
Klaproth, a German chemist, and named after
the planet Uranus.
•Over 1939-45, most development was focused
on the atomic bomb.

4. Origin and History
• 1950s, Start penetration of Nuclear
power in Electricity Market.
•1951, ERB-I initially produced about
100kw from nuclear reactor near
Arco, Idaho.
• 1960, 17 nuclear power reactors, with capacity
of 1200MWe.
•2012, 31 countries, 435 nuclear plant ,370 GW in
operation, 12.3% world electricity.
