Nuclear Power Plant-> Types of Reactors-> CANDU - Heavy water reactor. They may be run on recycled uranium from reprocessing light-water reactor (LWR) used fuel, or a blend of this and depleted uranium left over from enrichment plants. CANDU/PHWRs generally use natural uranium (0.7% U-235) oxide as fuel, so they need a more efficient moderator (the material that slows or moderates the speed of the neutron so it hits the next nucleus at the right speed to split, or fission, it). The G-S process, while capable of supplying the massive CANDU build programme from the late 1960s to the late 1980s, is expensive and requires large quantities of toxic H2S gas. 12) https: ...
