reactor types

NameFull NameSpectrumCoolantModeratorCycleDescription
PWR Pressurized Water Reactor THERMAL H2O H2O Rankine Most common nuclear reactor. Water is kept under high pressure to prevent boiling in the core.
BWR Boiling Water Reactor THERMAL H2O H2O Rankine Water boils directly in the reactor core to generate steam for the turbines.
CANDU Canada Deuterium Uranium THERMAL D2O D2O Rankine Uses heavy water for moderation/cooling, allowing use of natural (unenriched) uranium.
SFR Sodium-Cooled Fast Reactor FAST Na Rankine Uses liquid metal sodium. No moderator (fast spectrum) allows for breeding fissile fuel.
AGR Advanced Gas-cooled Reactor THERMAL CO2 C Rankine British design using CO2 coolant and Graphite moderator. High thermal efficiency.
HTGR High Temperature Gas Reactor THERMAL He C Brayton Uses Helium coolant and Graphite. Capable of very high temperatures for process heat or hydrogen production.
