Terminology

• 1)Nuclear power uses nuclear fission to heat
  water into pressurized steam, which turns a
  turbine generator creating electricity.
• 2) Nuclear fission is a nuclear reaction that
  occurs when a nucleus splits into smaller nuclei,
  and releases gamma radiation.
• 3) Radiation sickness occurs when someone is
  exposed to radiation it causes damage to blood
  cells, and symptoms include nausea, vomiting,
  fever, weakness, fatigue, hair loss, and is often
  fatal.
• 4) Scram is "an emergency shutdown of a nuclear
  reactor", its an acronym for "safety control rod
  axe men".
• 5) A steam turbine creates power when steam,
  (vaporized water) hits blades on a wheel, causing
  it to rotate rapidly, creating power.
• 6) Core meltdown is when the reactor core cooling
  fails, and the emergency core cooling fails, the
  core heats up until its a "molten mass".
• 7) "Plutonium is a radioactive chemical
  element". It is primarily created in nuclear
  reactor, and is shiny and tarnishes easily.
• 8)A nuclear reactor is a device in which nuclear
  chain reactions are initiated, controlled, and
  sustained at a steady rate.
• 9)Decontamination is the process of removing
  contamination, particularly the cleaning off of
  dangerous materials.
• 10)Radioactive exposure, also called radiological
  contamination, is the uncontrolled distribution
  of radioactive material in a given environment.
• 11)Cesium 137 is a radioactive isotope of cesium,
  which is formed mainly as a fission product by
  nuclear fission. It has a half-life of 30.07
  years, and decays by beta decay.
• 12)Strontium 90 is a radioactive isotope of
  strontium, with a half-life of 28.8 years.
• 13)A containment vessel consists of a barrier
  that successively includes fuel cladding, primary
  vessels, and thick shielding. As a final barrier,
  the reactor is housed in a containment structure.
• 14)There are several types of graphite moderated
  nuclear reactors that have been used in
  commercial electricity generation.
