Nuclear Energy
By Sam Reiter, Ethan Andersen, Austin Tang, and Emilee Hirsch
How easy is it to convert this source into usable energy?
How do we get Uranium?
Uranium Enrichment
Wolf Creek Nuclear power plant.
Wolf Creek has been safely providing clean, reliable energy to the citizens of Kansas and Missouri since 1985. The plant generates about 1,200 megawatts of electricity, which is enough energy to power more than 800,000 homes!
How could this source of energy be used in school?
Could this form of energy be used for transportation?
Could this energy be used in our homes now?
It could be we just need to be able to convert quicker. There are already many places that are powered with nuclear energy. Many sources say in 50 years we will have doubled the use of nuclear energy.
Some Sources of Radiation
Does this cause any noise pollution?
How does this form of energy contribute to any pollution on land?
Nuclear power is a clean energy source that generates electricity for one in five homes and businesses in the United States without producing or emitting any greenhouse gases, including carbon dioxide. It is truly a solution to pollution, and nuclear power plants currently generate 73 percent of all carbon-free electricity in America
Does nuclear energy pollute the air?
Does nuclear energy pollute the water?
Nuclear energy can pollute the water with heavy metals and salts that build up in the reactor's water supply, but this is the same as a coal reactor, because water is primarily used to cool excess heat from plants. The water from a nuclear power plant is still not considered radioactive because it never comes in contact with radioactive materials.
Nuclear has the highest capacity factors, or availability, of any source of electricity. It’s available 90 percent of the time, compared to 34 percent for wind and just 25 percent for solar.
Nuclear has the lowest production costs of any generating source.
Uranium, used to make nuclear fuel, has stable prices and is abundant worldwide, thus providing a high degree of energy security.
Lower carbon dioxide levels.
Technology is already developed.
Power generating capacities large enough to supply industrial and city needs.
Nuclear waste can be reduced through waste recycling and reprocessing.
Nuclear reactors use Uranium and its instability to produce lots of heat to heat water into steam that turns a turbine, which generates power. So, how do we get it?
The possibility of a meltdown
High construction costs
Radiation (possibility of cancer, hair loss, sterility, seizures, and heart failure for workers).
Target for terrorism
Waste lasts 200 – 500 thousand years.
Uranium Mining
Uranium is mined through open pit mining, underground mining, and leaching. The U.S. has about 300 million pounds of Uranium in Texas, New Mexico, and Wyoming.
17% of Uranium consumed in the United States is mined in the U.S. The rest is imported largely from Russia, Australia, and Canada.
On submarines and many other Naval ships a nuclear reactor is used to produce steam to drive a turbine which can either generate electricity to drive electric motors, or turn the propeller shafts directly.
Nuclear ships, like aircraft carriers, can steam at 30 knots (nautical miles per hour) under nuclear power.
We could use the electricity generated by nuclear power plants to power the school.
It isn't. Converting uranium into energy takes a very long time (almost 3 years) and is a very complex, painstaking process.
Before mined uranium can be used, it must be enriched. The uranium in reactors is uranium isotope 235,while most natural uranium is uranium isotope 238. The 0.72% of uranium isotope 235 in natural uranium is enriched into uranium with 3.5% of its uranium being isotope 235. By comparison, nuclear weapons have uranium enriched to 90%, with 27 times more isotope 235 than reactor uranium.
Waste Disposal
The closest and first Kansas Nuclear energy operating place.
Once the nuclear fuel is 'spent', in which it can no longer sustain enough nuclear reactions to heat the water that creates the steam that turns the turbine that generates power, it is stored on-site or buried underground in concrete. As of now, there are no great storage methods for the uranium that is still highly dangerous even though it is spent.
Nuclear reprocessing
Nuclear reprocessing is a technique used to separate fissionable plutonium from the spent fuel to be reused in the reactor. Finally, breeder reactors are not restricted to only using recycled plutonium and uranium as fuel, and they can multiply the energy extracted from uranium about 60 times.
The End
Nuclear energy is actually one of the only expandable, large scale energy source that doesn't pollute the air and doesn't emit carbon dioxide into the air.
The factories that produce the nuclear energy can create some noise pollution. but either than that there is no noise pollution involved.
We think that this is a good form of energy that can work well for the U.S. It is safe, clean, and powerful enough to generate large amounts of electricity. Nuclear energy would be more worth using because nuclear energy is much cleaner and safer than a plant that burns fossil fuels. Also, nuclear plants are more efficient and generate more energy than a fossil fuel powered plant. As of 2012, 14 percent of the world's electricity is generated by nuclear energy.


It is very easy to convert nuclear fuel into usable energy. Nuclear reactor cores are submerged in water, where nuclear reactions boil the water and the steam travels through pipes to turn a turbine that generates readily usable electricity.
