Heavy Water Plant at Manuguru, Andhra Pradesh is based on
the Bithermal Hydrogen Sulphide-Water (H2S-H20)
Exchange Process. This plant with a capacity of 185 Metric
Tones per Year is the second in India based on this process.
The first one located at Kota, Rajasthan had complete
technology developed indigenously with the close interaction
between Bhabha Atomic Research Centre and the Heavy Water
Board. 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. The nearest railway station is 10 Km. from plant
Based on the process package developed by D.A.E., the
project was executed on a total management basis with
Engineers India Ltd. as consultant for the main plant and Tata Projects Ltd.
for the captive plant. The captive power plant consist of 3
pulverised coal fired boilers and 3 nos. of extraction
condensing turbines each capable of supplying 30 MW power
and the required process steam at 32 and 8 atm. pressure.
The main plant consists of two streams, each designed to
produce 92.5 MT/Y of nuclear grade heavy water and the
processes namely isotopic exchange reaction between H2S
and H2O followed by vacuum distillation.
