  11. 11. Results • ≈ 200 MeV is released per fission • Most of this becomes kinetic energy of fission fragments • A room temperature atom has about 1/40 eV kinetic energy -- fission fragments have 400,000,000 times that energy! • Punchline: fission fragments are hot

  18. 18. What’s in spent fuel?
  19. 19. • Something that is radioactive emits radiation • Radiation is energy traveling trough space (light, microwaves, x-rays, gamma rays, etc.) • Radioactive materials decay into non-radioactive materials • Spent nuclear fuel becomes less radioactive over time doe.gov
