5 Matching questions

  1. Meltdown
  2. Low Level Radioactive Waste
  3. Fission
  4. Plutonium
  5. High Level Radioactive Waste
  1. a a synthesized (man made) unstable, fissionable material
  2. b Gives off low levels of ionizing radiation for a shorter time period, requires safe storage for 100 to 500 yrs
  3. c Waste which gives off high amounts of ionizing radiation for a short time and, lower amounts for a long time, requires safe storage for 240,000 yrs
  4. d the process by which the nucleus of a heavy atom splits into two or more fragments; the process releases nuetrons and energy
  5. e an accident in a nuclear reactor where the fuel overheats and melts the reactor core

5 Multiple choice questions

  1. Radiation which dislodges electrons form the molecules they hit causing them to change chemically and impair normal functions, effects: burned tissue, anemia, impaired cell division, cancer
  2. a device that converts the kinetic energy captured by a turbine into electrical enrgy
  3. A bomb developed in the 1940's by the US, uses critical mass of U-235 or plutonium to create uncontrolled chain reaction (fission) which releases massive amounts of energy, which causes catastrophic destruction
  4. sub-critical masses of fissionable U-235 or plutonium
  5. The part in the containment building where the fuel rods come together to begin the chain reaction, and where the control rods are placed in between the fuel rods to slow the chain reactions

5 True/False questions

  1. Uranium 235a stable non-fissionable isotope of uranium


  2. Nuclear ReactorReactor using fuel/control rods to create heat, used to make steam to eventually spin a turbine


  3. Cooling Towertower in which the extremely high temperature steam (from the light water plant design) is cooled and condensed back into water to be reused


  4. Wind TurbineDevice that converts mechanical energy into electricity by spinning a copper coil inside a magnetic field


  5. Fossil FuelPlant material, manure or any other organic matter that is used as an energy source
