2. These split apart and produce more neutrons… 3.…which then
collide with other heavy, unstable atoms, and the process continues.
How does nuclear fission work?
1. Neutrons are fired at heavy, unstable atoms.

Using this chain-reaction with
control gives us
nuclear power
Using this chain-reaction
uncontrolled gives us
a nuclear bomb

Nuclear power plants
How do we all use oil in our every-day lives?
1. Fission occurs. Moderator – slows down neutrons
(so that fission can happen)Control rods – absorb neutrons (to keep the chain-reaction in check)

2. Fission heats up water
3. Hot water boils, creating steam
4. Steam drives the turbines, generating electricity!

5. Cold water from the cooling tower converts steam back to liquid water (it is
recycled)

We will read the article aloud, together
In your notes: make a list of pros of using nuclear power (at least four)

Leaks from nuclear power plants can release radiation, which damages DNA cancer, birth defects, etc.
1. Small risk of large accidents
Birth defects from Uranium exposureBurns from radiation

Mechanical failure and human error caused the cooling water to drain from the reactor, melting the fuel rods and releasing radiation.
Most radiation remained trapped inside and didn’t hurt anyone.

U.S. power plants store enough radioactive waste to fill a football field 10 feet high
This waste is stored in 125 sites across the country. The National Academy of Sciences reported that most of these sites are vulnerable to terrorist attacks.
