D2o is used in nuclear reactor for
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure to avoid boiling, allowing it to reach higher temperature (mostly) without forming steam bubbles, exactly as for pressurized water reactor. While heavy water is very expensive to isolate f… WebApr 14, 2024 · Both iodine-131 and caesium-137 are used in nuclear medicine radiotherapy applications which means they have sufficient energy to cause cell death and mutation. In other words they are capable of producing cancers.
