- Expensive, bad reputation with the public, waste is radioactive for years
- High risk of nuclear accidents
- Lots of background radiation produced, waste is hard to deal with
4. How do moderators increase rates of fission?
- Slowing down fast-moving protons because slow moving protons are more likely to be absorbed by the uranium atom
- Slowing down fast-moving neutrons because slow moving neutrons are more likely to be absorbed by the uranium atom
- Slowing down fast-moving electrons because slow moving electrons are more likely to be absorbed by the uranium atom
- Removing the thermal energy produced in fission reactions so it can be used to heat water to produce steam to power turbines
5. What is terminal velocity?
- A constant velocity - when air resistance is equal to the weight of the object and the resultant force is now 0
- An alternating velocity
- A slow velocity
- A constant velocity - when resultant force is 100
