• Which is the largest source of power in the United States?

• Do you feel this is good or bad?

Nuclear Energy Around the World

As of October 2010, 29 countries worldwide are operating 441 nuclear reactors for electricity generation and 61 new nuclear plants are under construction in 15 countries.

Nuclear power plants provided 14 percent of the world's electricity production in 2009.

In total, 16 countries relied on nuclear energy to supply at least one-quarter of their total electricity.

How does it work?• Uranium is the source of fuel. • A neutron basically splits the uranium atom therefore causing the nuclear fission to

take place.• When the split of the uranium atom happens you get more neutrons and heat is created.• The heat that is created is transferred to water (primary coolant). • From there the water runs through a steam generator where it never comes in contact

with the secondary water. This allows the radioactive fluid to remain separate from the secondary part of the plant.

• The heat from the primary running through the steam generator creates super heated steam.

• We then harness the steam to spin turbine generators to create electricity, spin the propulsion train to push the ship through the water and to launch aircraft off the catapults.

• Then as that steam cools it condenses back to water where it returns to the steam generator to repeat the cycle.

WHAT IS RADIATION AND WHAT TYPES ARE THERE?

• Radiation: energy that travels in rays or particles

• Natural sources of radiation are found everywhere from water, soil, air, and even the food we eat

SOURCES OF RADIATION

THE COOKIE QUESTION: If you had an THE COOKIE QUESTION: If you had an alpha, a beta, a gamma, and a neutron alpha, a beta, a gamma, and a neutron

cookie, which would you:cookie, which would you:

• THROW AWAY• PUT IN YOUR

POCKET• EAT• HOLD IN YOUR

HAND

• α Alpha particle• Β Beta particle• γ Gamma • n Neutron

Cookie Question Answer:Cookie Question Answer:

• Alpha particle: Hold in your hand because it is shielded by dead skin cells.

• Beta particle: Put in your pocket because it is shielded by thick clothing.

• Gamma: Eat, because one gamma is very small, and the chances are low that it will even contact any part of your body.

• Neutron: Throw away because we use water to either moderate or shield neutrons, and your body is made of 70% water.
