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
