5 True/False Questions

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


  2. Ionizing Radiationa chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically.


  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. Control Rodssub-critical masses of fissionable U-235 or plutonium


  5. Photovoltaic CellsNeutron absorbing material that slows the chain reaction
