Nuclear energy is a clean and efficient power source generated through the fission of Uranium-235. While it produces minimal CO2 emissions and yields substantial energy output, it also generates radioactive waste and poses safety risks. Learn about how nuclear plants work, the types of reactors, and locations of nuclear facilities. Explore the challenges of nuclear energy for the future and potential solutions.

Nuclear energy By Jeffrey
What is nuclear energy? • It is a clean energy source. • It is made when neutrons hit Uranium 235. • The energy in nuclear plants is fission.
Benefits and Negatives Some benefits are: • It produces very little Carbon Dioxide. • The uranium pellets are very small, but one pellet produces the same amount of energy as 150 gallons of oil! Some negatives are: • Nuclear energy produces radioactive waste. • Nuclear energy is unrenewable.
How does nuclear energy work? • The fission produces heat that heats water into steam. • The steam turns a turbine to make electricity • The steam cools back into water in a cooling tower.
Types of reactors • There are two types of reactors: • boiling water reactors and pressurized water reactors. ( BWR and PWR)
BWRs • BWRs work by turning water into steam. • The steam turns a turbine that makes electricity • The steam cools down back into water in a cooling tower.
PWRs • PWRs work by heating pressured water so that it doesn’t turn into steam • The hot water heats water in a steam generator • That steam turns a turbine. • The hot water flows back to the “engine” to be reheated
Where? • Nuclear energy is in many states such as: • Missouri, Illinois, Texas and more! • The one nuclear plant in Missouri is located in Callaway County, which is 80 miles away from St. Louis.
Nuclear for future? • Nuclear wouldn’t be a good energy source for the future because: • Nuclear is unrenewable • Nuclear is very dangerous, and we need a safer way to store it. • However, scientist are thinking of burying radioactive waste in Yucca Mountain
