Inside a nuclear fission reactor, a single fission event of a uranium-235 nucleus produces a tiny amount of thermal energy. Yet, the reactor core can continuously generate hundreds of megawatts of power to supply the national grid.

The electrical demand from the grid fluctuates throughout the day.

Explain:

  • how a continuous chain reaction is established to release vast quantities of energy
  • how control rods are adjusted to regulate the rate of energy output when the grid's electrical demand changes.
