Question

Explain Nuclear Fission?​

Answer 1

Answer:

Nuclear Fission is the splitting up of an unstable nucleus by firing a neutron at it, releasing energy, neutrons and two roughly equal-sized fragments.

Explanation: When the neutron is fired at the unstable nucleus e.g. uranium 235. It splits into roughly equal-sized fragments, releasing several neutrons and energy. These neutrons can then go on to cause a chain reaction which is typical of a nuclear bomb when uncontrolled. However, inside power stations, the reaction is controlled using control rods and this ensures only 1 neutron of the several released goes on to cause another nuclear fission reaction. Nuclear Fission is used in a power station to release heat, which boils water, releasing steam, which turns a turbine, which runs a generator and generates electricity.
