fissionreactorbased
Fission reactor-based technologies describe energy systems that derive most of their heat and electricity from controlled nuclear fission in a reactor core. In these systems, heavy nuclei such as uranium-235 or plutonium-239 are split by neutrons, releasing energy as heat that is captured by a coolant to produce steam and drive a turbine.
Core components include fuel assemblies, a neutron moderator to slow neutrons, a coolant to transfer heat, control
Major reactor types include light-water reactors, which use ordinary water for cooling and moderation (pressurized and
Safety is central to fission reactor-based systems. Features include multiple barriers, emergency cooling, rapid shutdown, and
Ongoing research aims to improve safety, efficiency, and flexibility, with efforts on advanced fuels, enhanced cooling,
