How does nuclear fission create energy?

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.

Nuclear fission creates energy by splitting uranium atoms in a reaction that releases heat and radioactive particles. The released neutrons then trigger a chain reaction with other uranium atoms, producing more energy.
