WebThese advanced reactors, envisioned to vary in size from tens of megawatts up to hundreds of megawatts, can be used for power generation, process heat, desalination, or other industrial uses. Advanced Small Modular Reactors (SMRs) are a key part of the Department’s goal to develop safe, clean, and affordable nuclear power options. WebThe Pressurized Heavy Water Reactor (PHWR-220) is a 235 MWe pressure-tube type reactor derived from the Canadian CANDU design. It uses heavy water (D2 O) both as a primary coolant and as a neutron moderator. Pressure tubes made of Zr-2.5%Nb contain the 0.5 m long cluster-type fuel bundles containing 19 Zircaloy-4 cladded pins of natural UO 2.
