Karachi Nuclear Power Plant (KANUPP): As case study for techno-economic assessment of nuclear power coupled with water desalination

This paper is focused on the development of technical and economical prospective of Karachi Nuclear Power Plant (KANUPP) in terms of various desalination technologies. During the first phase, an initial research contingency to desalination technologies already running at KANUPP was discussed and evaluated for economic assessment. In the next phase, mathematical model was developed for calculating various parameters of desalination technologies. During this step, simulation model from IAEA (International Atomic Energy Agency) named as DEEP & DE-TOP were used for calculating various desalination techniques including Reverse osmosis (RO), Multi effect desalination (MED), Multi stage desalination (MSF) and also for coupled technologies i.e., RO+MED and R0+MSF. Different parameters including capital/water cost and thermal desalination parameters were calculated for coupled desalination technologies for KANUPP. Number of stages for coupled KANUPP desalination plant in terms of experimental and computational analysis were carried out. The calculation shows that water cost for each coupled desalination technologies have varying trends. The objective of the research was to developed technical and economical viable model for coupled nuclear reactor desalination system. The research gives an indication to developed experimentally viable KANUPP desalination plant. - Highlights: • Techno-economic analysis of KANUPP for various desalination technologies. • Mathematical model development for calculating various desalination techniques. • Calculation shows that water cost for each coupled technologies have varying trends. • Viable techno-economical model for coupled nuclear reactor desalination system. • Solution for experimentally viable coupled KANUPP desalination plant.
