Nuclear Reactor
An engineered facility in which a controlled self-sustaining nuclear chain reaction is maintained to generate thermal energy for electrical power generation.
Governing formula
Multiplication Factor k = Neutrons in generation (i+1) / Neutrons in generation i
SI unit
MWth or MWe (Power Capacity)
In depth
Utilizes enriched fissile fuel (U-235 or Pu-239), a neutron moderator (water or graphite) to slow down fast neutrons, control rods to absorb excess neutrons, and a coolant system to transfer fission thermal heat to steam turbines.
Examples in the real world
Commercial Pressurized Water Reactors (PWR) generating zero-carbon baseload electricity for power grids.
