Transcript of Fusion/Fission/Nuclear Energy
Energy Grant Mattson Tyson Kauffman By: Fusion smashes atomic nuclei together to make heavier nuclei.
End products usually light, stable nuclei
Fusion reactors not yet producing electrical power (1) Fusion Citations Fission http://reactor.engr.wisc.edu/tour/fission.htm
http://library.thinkquest.org/26026/History/nuclear_power_s_effects.html Does not emit harmful gases
Preserves land and habitats
Produce low-cost power
Ranked one of the safest industries to work in the U.S (1) Benefits of Nuclear Plants Risks of Nuclear Plants Radiation- Affects peoples' health; causes cancer to those who live near power plants
Radioactive Waste- Disposed underground
Nuclear Reactor Accidents- Malfunctions, which lead to meltdowns (2) Nuclear Reactors Nuclear fission used in reactors
Large amount of energy released (2) How is nuclear power generated? Nuclear power is generated using Uranium.
Generated in a nuclear reactor
Uses Uranium as fuel
Heat generated by nuclear fission (1) Types of Power Plants (By Generation) 1st Generation- Early reactor prototypes
2nd Generation- Reactors built up to the late 1990's
3rd Generation- Improvements on 2nd generation reactors
4th Generation- Reactors currently being researched (1)
Fission is when the nucleus of an atom splits because of impact with another particle.
Nuclear fission produces energy for nuclear power.
This process also drives a nuclear explosion, but must happen quickly to create the explosion.
Nuclear fission produces free neutrons and photons, or gamma rays. (2) Position on Nuclear Power Nuclear power can be very useful, but it shouldn't be used to the extent of affecting humanity and the environment. Sometimes, it can result in disaster.
If an accident occurs, the radiation will spread and possibly damage peoples' health. (2) Pictures: and http://quest.eb.com/
