  1. 3. chemical reaction between a fuel and an oxidant that produces an oxidized product.
  2. 4. is the process in which two nuclei are joining together to produce a single, heavier and larger nucleus
  3. 5. heavy hydrogen is isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). Deuterium has an atomic weight of 2.014.
  4. 6. force that act between two or more nucleons.
  5. 7. is the heaviest and only radioactive isotope of hydrogen, it has two neutrons in the nucleus and one proton. Tritium is produced naturally in the upper atmosphere when cosmic rays strike nitrogen molecules in the air.
  6. 9. is a state of matter similar to gas, but with most of the particles ionized. This means the particles have an increased or reduced number of electrons.

  1. 1. plasma confinement refers to the act of maintaining a plasma in a discrete volume. Confining plasma is required in order to achieve fusion power
  2. 2. force - The electromagnetic force is a type of physical interaction that occurs between electrically charged particles. It acts between charged particles and is the combination of all magnetic and electrical forces. Electromagnetic force can be attractive or repulsive.
  3. 8. toroidal device for generating controlled fusion processes in hot plasma,
