Pressurised heavy-water reactor
Heavy water (deuterium oxide) kept under pressure as both coolant and moderator, which absorbs far fewer neutrons than ordinary water and so lets the reactor run on natural, unenriched uranium. That is the CANDU design's defining trade: heavy water is expensive to produce, but the fuel needs no enrichment plant. Fuel is natural or slightly enriched uranium oxide, usually in horizontal pressure tubes, refuelled online without shutting the reactor down.
