Turkey Point Power Plant

• Built on 12, 700 acres in Homestead
• Opened in 1972
• Cost to build both reactors 235,000,000.00
• Employs 680 workers

Nuclear Energy

• Fission releases the energy
• Radiation is a product of this energy release
• Three types of radiation are Alpha, Beta and
  Gamma
• We are exposed to about 360 mRems of radiation
  annually
