Nuclear energy is produced through the splitting, or fission, of a uranium atom in the core of a nuclear reactor. When hit by a neutron, the atom divides and releases two other neutrons, as well as heat and radioactive particles. The newly released neutrons then go on to bombard other uranium atoms. This sets off a chain reaction that continues until the uranium fuel is used up.
Please shorten this.
I hope a chain reaction is NOT the result.
Fission creates energy because bonding energy is in heavy atoms, when broken into smaller bits, that bonding energy (in the form of mass) is released as energy. As long as the reaction is controlled, usable power can be extracted from the reaction.
Hmmm. That is not shorter.
Dividing heavy atoms released much energy, that had been stored as mass.
