Fission means to split atoms; fusion means to ______ them together.
Join or Fuse
What is the solid, used fuel from a reactor called

One major advantage of nuclear energy is that, unlike burning fossil fuels, it emits none of these types of gases into the air during operation.
Greenhouse gases specifically carbon dioxide
True or False: A nuclear reactor can explode like an atomic bomb.
False
What is contained in the nucleus?

The reaction in a power plant is a controlled ______ reaction.
Fission
This waste remains radioactive for thousands of ______.
Years
Nuclear power plants are considered one of America's most reliable energy sources because they can run at full capacity over 90% of the time, often for 1.5 to 2 years between refueling.

True or False: All life on Earth is subjected to some natural background radiation.
True
A nuclear plant uses heat from fission to boil water, creating ______ to spin a turbine.
Steam
What is the term for the time it takes for half of a radioactive substance to decay?
Half-life
What is the general term for energy from unstable atoms
Radioactivity or ionizing radiation
This is the primary challenge and concern associated with nuclear energy, which involves dealing with radioactive materials that are no longer useful.
Radioactive waste

What's the name for the energy released from the nucleus of an atom?
Nuclear Energy
Name one method of protecting yourself from radiation
time, distance, and shielding

Background radiation
True or False: One small uranium fuel pellet can produce the same amount of energy as a ton of coal or three barrels of oil.
True
What are the rods inserted into a reactor to control the rate of fission
Control rods
