General Features & Process Description

Heavy Water Plant, Manuguru is the largest Heavy Water Production facility, supporting the Indian Nuclear Power Program. It is an ISO-9001 (2015) & ISO-14001 (2015) certified organization and is the flagship of Heavy Water Board. This plant is the second of its kind in India based on this process. The first of its kind is located at Kota, Rajasthan had complete technology developed indigenously with the close interaction between Bhabha Atomic Research Centre and the Heavy Water Board efforts. The plant consists of two streams of Exchange Units, based on bi-thermal Hydrogen Sulphide - Water (H2S-H2O) isotopic exchange process followed by vacuum distillation with total installed capacity of 185 MT/year of Nuclear Grade Heavy Water (D2O). Power & Steam requirements are met by its own coal based Captive Power Plant. The captive power plant consists of 3 nos. of pulverized coal fired boilers and 3 nos. of extraction condensing Turbines each capable of generating 30 MW power and the required quantity of process steam at 30 ata and 8 ata pressure.

HWP(M) is situated on the banks of river Godavari at Mittagudem village near Bhadradri and 12 KM away from Manuguru, in Bhadradri-Kothagudem district of Telangana state. The Manuguru site was chosen because of its proximity to Singareni coal fields and Godavari river which provide respectively large quantities of coal and water required for the plant.

Water from Godavari river is drawn and necessary purification is done before feeding it to Exchange Units where D2O content is enriched from 150 ppm to 15% by H2S-H2O bi-thermal isotopic exchange process in a three stage cascade and further enriched by vacuum distillation to produce 99.8% D2O.

HWPM is committed for safe and efficient operation of the plant and exports commercial grade Heavy Water.

The zero date of the project was 01.09.1982. The consultants for CPP and Main Plant were M/s TPL and M/s Engineers India Limited respectively. Stream-2 of Exchange unit was commissioned by Dec,1990 and the stream-1 by Nov,1991. The plant reached near to its rated capacity in a short period of 3 years after commissioning.

After meeting the primary mandate of producing the Heavy Water for Indian Nuclear Power Program, HWPM had taken up the diversification activities of enrichment of Boron-10 isotope production facility for INPP, Harnessing of Solar energy and O-18 enriched water production facility.
