What is nuclear energy?
Its important for you to know that everything around you is made up of tiny objects called atoms. Most of the mass of each atom is concentrated in the center (which is called the nucleus ), and the rest of the mass is in the cloud of electrons surrounding the nucleus. Protons and neutrons are subatomic particles that comprise the nucleus.
Under certain circumstances, the nucleus of a very large atom can split in two. In this process, a certain amount of the large atom’s mass is converted to pure energy following Einstein’s famous formula E = MC2 , where M is the small amount of mass and C is the speed of light (a very, very large number).
In the 1930s and ’40s, humans discovered this energy and recognized its potential as a weapon.
Technology developed in the "Manhattan Project" successfully used this energy in a chain reaction to create nuclear bombs. Soon after World War II ended, the newfound energy source found a home in the propulsion of the nuclear navy, providing submarines with engines that could run for over a year without refueling.
This technology was quickly transferred to the public sector, where commercial power plants were developed and deployed to produce electricity.
