what is nuclear fusion?

two light nuclei join together to form a larger heaver nucleus, releasing energy as radiation

New cards

what conditions are needed for nuclear fission?

  • nuclei = +1 charge - electro-statically repel

  • massive pressure and temperature are required to overcome repulsive forces

what is the equation for nuclear fusion

2^_1H + 1^_1H —> 3^_2He + energy

what are the pros and cons of nuclear fission?

Pros

Cons

  • Hydrogen is abundant in seawater

  • need very little fuel

  • Doesn’t produce greenhouse gas

  • No need to keep chain reactions under controls

  • Tritium could bond with water to make radioactive water

  • May be too expensive to ever build

  • Fuel isotopes (tritium and He²) are scarce

  • we don’t have the technology
