*Difficult to safely dispose of nuclear waste.
*There is a small risk of meltdown.
==Key Stage 4==
===Meaning===
'''Nuclear Power''' is a method used to generate [[electricity]] using [[Nuclear Fuel|nuclear fuel]].
===About Nuclear Power===
: [[Nuclear Fuel]] can be used to provide [[power]] by generating electricity that can be sent to houses and industry.
: [[Nuclear Fuel]] has [[energy]] in its [[Nuclear Potential Energy Store|nuclear potential energy store]] which can be easily transferred into its [[Thermal Energy Store|thermal energy store]].

|}
: 1. [[Nuclear Fuel]] undergoes a [[Nuclear Reaction|nuclear reaction]] in the [[Reactor Core|reactor core]].
: 2. Water in the [[Reactor Core|reactor core]] is heated and passed through a heat exchanger.
: 3. Water in the [[Reactor Core|reactor core]] becomes contaminated with [[radioactive]] [[material]] so the heat exchanger heats up uncontaminated water.
: 3. The uncontaminated water turns to steam and passes down pipes to turn a turbine.
: 4. The turbine causes a generator to spin.
: 5. The generator makes an electrical current.
====Advantages====
*Can work continuously.
*Power supply can be varied depending on demand.
*Few [[Thermal Power Station|power station]]s needed to supply a large number of houses.
*High energy density (1kg of Uranium can provide the same energy as 10,000kg of coal).
====Disadvantages====
*Cost of fuel.
*Difficult to safely dispose of nuclear waste.
*There is a small risk of meltdown.
