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
