  7. Recognize that nuclear energy is a controversial issue. Be able to state some concerns regarding this issue and some facts that support its use.
  8. Understand some concerns regarding the environment as a result of the use of nuclear and non-nuclear methods of electrical generation.
  9. Develop and defend a position which either supports or rejects the use of nuclear energy for peaceful purposes.
  10. Develop and defend a position which either supports or rejects the use of nuclear energy for military purposes.
Lessons Questions

Key Concepts
  • CANDU reactor uses natural uranium ore as its fuel.
  • Saskatchewan has abundant deposits of uranium ore.
  • Fuel bundles, the calandria, heavy water, control rods, and condensers are important components of the CANDU reactor.
  • Nuclear reactors cannot explode like a nuclear bomb.
  • In a nuclear reaction accident a meltdown may occur if there is a loss of coolant.
  • The nuclear fuel cycle starts when uranium ore is mined and stops when it has been disposed of after use.
  • Tailings are the waste material after the uranium has been extracted. They are slightly radioactive and must be disposed of properly.
  • When a nuclear reactor has completed its useful service, it is decommissioned.
  • Nuclear energy for peaceful purposes has many pros and cons.
