Nuclear power can bee produced by process called fusion . In this kind of reaction , the nuclei of the fuel come together and do not break apart . Nuclei is the center of atom consist by Protons and Neutrons . In Nuclear Fusion , unlike Fission , occurs only with small atoms whose nuclei contain very few Protons and Neutrons . The fuel consist of two different forms of hydrogen . To produce Nuclear Fusion , pairs of nuclei meet , so their proton and neutrons fuse together and become a single nucleus , and a spare neutron is left over . The fused nuclei and neutrons move off at high speed and producing great heat . In nuclear fusion reaction , radiation is not emitted , but the spare neutrons are harmful .
To make the nuclei and neutrons meet and fuse together , the atoms must be banged together with very powerful force . This can only be done by heating the fuel to temperatures of millions of degrees .
Nuclear fusion powers the Sun , and occurs in thermonuclear weapons .

| Deuterium-Deuterium fusion |
When deuterium ( Gas fuel which a form of hydrogen and made from water) nuclei ( 1 proton and 1 neutron ) fuse with another deuterium nuclei , a neutron left over then 2 protons and 1 neutron forms a normal helium nuclei .
When tritium ( other gas fuel , another form of hydrogen and made by bombarding lithium ) nuclei ( 1 proton and 2 neutrons ) fuse with deuterium nuclei , a neutron left over then 2 protons and 2 neutrons forms an unstable form of helium .
