About HWB

Heavy Water Board (HWB), a constituent unit of Industries and Minerals Sector under Department of Atomic Energy, is primarily responsible for production of Heavy Water (Deuterium Oxide-D2O) which is used as a 'moderator' and 'Coolant' in the nuclear power as well as research reactors. HWB has mastered the complex production technology using two chemical exchange processes viz. H2S-H2O bithermal process and NH3-H2 monothermal process. India is one of the largest manufacturers of heavy water in the world and is meeting the heavy water requirements of the Indian Nuclear Power Programme. The plants based on Ammonia-Hydrogen (NH3-H2) exchange process are linked to the ammonia fertilizer plants for synthesis gas feed supply while H2S-H2O based plants are independent in this respect. HWB is successfully operating six Heavy Water Plants in the country. A technology demonstration plant using Water-Ammonia (H2O-NH3) deuterium exchange to make the ammonia based Heavy Water Plants independent of fertilizer plants is also developed and demonstrated at HWP, Baroda, Gujrat.  All Heavy Water Plants have well defined Safety & Environmental Policy and maintaining excellent records in these areas.

 

Heavy Water Board and its Plants are ISO Certified for Quality Management System, Environment Management System and Occupational Health & Safety Management System.

 

Heavy Water Product from HWB meets stringent quality specifications for international requirements. Heavy Water Board has successfully exported Heavy Water to countries viz. South Korea, China and USA.

 

HWB has set up production facilities for various Organophosphorous solvents viz. D2EHPA, TBP, TAPO, TOPO, DNPPA, DOHA etc. for meeting the requirements of DAE. This included development of the processes from laboratory synthesis through scale up to commercially viable plants. The solvents produced by HWB have found acceptability not only in DAE but outside as well.

 

HWB also has been successful in engineering / setting up and operating the boron isotope enrichment units based on different technologies to meet the requirements of fast breeder reactor programme. The other activities also include development of cryogenic process system and recovery of rare material from secondary sources.

 

Apart from the above, HWB has opened avenues for development and promotion of non-nuclear applications of Heavy Water and Deuterium. HWB has been successful in demonstrating the improved thermal stability of deuterated oral polio vaccine. HWB also has been working with various institutions in further development in these applications. HWB has been supplying deuterium gas for the manufacture of low water peak optical fiber. Synthesis of some of the D-labeled compounds extensively used in NMR has been taken up by HWB. HWB has also been offering Value Added Services and spin off technologies to other chemical process industries.
