ABSTRACT: The worldwide
demand for portable water is steadily growing due to population, industrial and
agricultural growth, the result is water shortages that are already reaching
serious proportions in many parts of the world. This is particularly true in Ghana where there is an increasing reliance on bottled water due to shortage of safe,
fresh drinking water. Nuclear and conventional co-production of electricity and
portable water has been identified as key solution to the perennial water
shortages in coastal towns in Ghana.
A reliable desalination cost date catering for site-specific condition in Ghana
is required for policy makers, planners, consultants, process engineers, plant
suppliers and researchers. This present paper is aims comparing the cost of
co-production of power and portable water using reverse osmosis (RO) plant
coupled with both nuclear and fossil power plant operating under different
cycles using the desalination economic evaluation programme (DEEP4.0) developed by the
international atomic energy agency (IAEA).
The study concentrates on conditions of seawater in Accra, Ghana.
Results show that co-production nuclear power plant operating on steam cycle
can be the most economic among a number of power-water production options.
