Heavy Water Board (HWB), an industrial organization under Department of Atomic Energy, is primarily responsible for production of Heavy water which is used as a 'Moderator' and 'Coolant' in the nuclear power reactors as well as research reactors. HWB is successfully operating six Heavy Water Plants in the country. HWB has mastered the complex production technology using two chemical exchange processes viz. (H2S-H2O) bi-thermal process and NH3-H2 mono-thermal process. India is perhaps one of the largest manufacturers of heavy water in the world as of today and the only country, which has mastered both these state-of-the-art processes to meet the heavy water requirements of the Indian nuclear power programme. Indigenously developed hydrogen sulphide as well as ammonia based plants have shown excellent performance in the last ten years in terms of production as well as safety records
