  1. QOTD • What is the major difference between fission and fusion?

  2. Fusion vs Fission Mr. Dunnum

  3. Fusion • Nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. • It is accompanied by the release or absorption of energy depending on the masses of the nuclei involved..

  4. Picture of Fusion

  5. Fusion • Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei and therefore are the most stable. • The fusion of two nuclei lighter than iron or nickel generally releases energy. • The fusion of nuclei heavier than them absorbs energy.

  6. Fission • A reaction in which an atomic nucleus of a radioactive element splits by bombardment from an external source, with simultaneous release of large amounts of energy, used for electric power generation

  7. Fission • Fission is Exothermic • The sum of the masses of the resulting nuclei is less than the original mass(about 0.1% less) • The “missing mass” is converted to energy according to E=mc2

  8. Energy production

  9. Nuclear Fuel Costs • Nuclear Fuel Costs Include • Uranium -Increasing Uranium Cost has Minimal Impact • Enrichment • Manufacturing • Waste Disposal • Total Nuclear Fuel Cost is Only About 0.5 cents per kilowatt-hour • Uranium accounts for only about 20% of this cost or 0.1 cents per kilowatt-hour
