Indian government agency

Heavy Water Board (HWB) is a constituent unit under the Department of Atomic Energy in the Government of India. The organisation is primarily responsible for production of heavy water (D2O) which is used as a moderator and coolant in nuclear power as well as research reactors. Other than heavy water, the HWB is also engaged with production of nuclear grade solvents and extraction of rare materials. India is one of the largest manufacturers of heavy water in the world. Similarly, India has one of the world's largest fleets of pressurized heavy water reactors producing most of India's nuclear power supply.
