heavy water reactors

Heavy water reactors use water containing a higher proportion of deuterium (a hydrogen isotope) instead of regular hydrogen. This heavy water acts as a neutron moderator, efficiently slowing down neutrons to sustain nuclear fission reactions. Because heavy water absorbs fewer neutrons, these reactors can use natural, unenriched uranium as fuel, reducing processing costs. They are known for their safety and efficiency, often used in countries seeking a reliable and flexible nuclear power source. Overall, heavy water reactors are a mature technology that enables effective nuclear energy production with minimal fuel enrichment.
