Nuclear Reactions
Fission
Energy is released when a large atom is hit by a neutron, it becomes unstable and splits into two or three neutrons
When this happens, some of the mass of the atom is lost - it has been converted into energy. The energy can be used to generate electricity in a nuclear power station
-
At each stage of the fission reaction, it increases speed and energy. If this continued to increase there would be an explosion.
In a nuclear reactor, the chain reaction is controlled by boron rods, which absorb neutrons.
Nuclear power stations
-
-
Parts of a reactor: fuel rods, the moderator, the control rods, coolant and the containment vessel.
-
-
Fusion
-
A fusion reactor would be an ideal way to generate electrical energy. In order for this to take place there needs to be an incredible amount of energy. The reaction can be sustained, however a plasma is formed at a temperature of a million degrees.
-
This ic called a nuclear reaction and can happen in two ways, fission and fusion
