NUCLEAR POWER =]

How does it work:
Inside a nuclear power station nuclear reactions are taking place in the fission reactor and coolant (cold water) is being pumped around the reactor and turned to steam by the heat generated by the reactions. The steam drives the electricity generating machine called the turbine.
Here are some simple steps to understand the process:
1) The water pressurizer keeps the coolant pressure high so that the water can't boil

2) Travels to reactor core which contains fuel and control rods

3) Coolant pump circulates water around reactor

4) Hot water produces steam in steam generator

5) Steam drives the turbine

6) The steam is condensed back to water and returned to the steam generator.

Benefits/Positives:
439 nuclear power reactors are in operation in the world in 31 countries. Nuclear power gives France the cleanest air of any industrialised country and also the cheapest electricity in Europe.75% of the electricity comes from nuclear power. It reprocesses nuclear waste to reduce the mass and make more energy. Reprocessing can potentially recover up to 95% of remaining uranium and plutonium in nuclear fuel and transform it into new mixed oxide fuel. It will reduce carbon emissions and increase energy security, as well as decrease dependence on foreign oil. The sun makes the energy from the nuclear reactions deep inside the earth, which makes it like a giant nuclear power station.

Negatives:

Nuclear power doesn’t produce emissions but does produce toxic radioactive waste. The best way to dispose this waste is to store it deep underground in leak proof concrete containers which must stay for thousands of years, while radioactivity slowly declines to zero. Unfortunately, this is dangerous and explosive and is unsafe.


Statistics:


Every second, the same amount of energy reaches earth from the sun as coal then the fired power station that could make from approximately 200,000 truckloads of coal.

1 kilogram of uranium generates as much electricity as 3000 tonnes of black coal, which is 7.5 million kilowatt hours of electricity.


Real Life events:


On April 1986 a nuclear reactor exploded and clouds of radioactive particles were blown across Europe. It contaminated food and water and a 30km radius evacuation zone had to be set up around the reactor. It took centuries before the radiation fell to a safe level in the zone.
