waste is also generated while decommissioning and dismantling
nuclear reactors and other nuclear facilities.
The most important reason the fuel has to be replaced every
few years is the fission products.
nuclear fusion:a nuclear reaction in which atomic nuclei of low atomic number
fuse to form a heavier nucleus with the release of energy.
E=mc2: the equation says that energy and mass (matter) are interchangeable;
they are different forms of the same thing. Under the right conditions, energy can become mass,
and vice versa.
E = mc2 is the key to understanding why and how energy is released in nuclear reactions.
