Abstract
Egypt has been suffering from severe water scarcity in recent years. It has only 10 cubic meters per captia (the average amount of water each person in a particular area uses on a daily basis) of internal renewable freshwater resources (according to World Bank, 2018). Concerns about global warming and water scarcity have motivated many researchers to consider the potential for nuclear desalination. There are numerous benefits of integrating a desalination plant with a nuclear power plant such as carbon-free electricity, low-marginal cost of generating electricity compared to fossil fuels, and a consistent power supply, unlike intermittent renewable electricity sources like wind and solar. This Study aims to improve the performance of a Reverse Osmosis (RO) seawater desalination unit already operational on the North coast of Egypt at Marassi Resort. This unit is assumed to be coupled with a nuclear power source (Dabaa nuclear power plant; four VVER-1200 nuclear reactors, which are capable of producing 1.2 GW each) by using DEEP software which is developed by IAEA to provide a simplified configuration and power consumption of the nuclear desalination unit depending on its capacity and desalination technology type. This improvement is achieved by using Six Sigma concept (DMAIC; Define-Measure-Analyze-Improve-Control) and operational risk assessment techniques. After assessing the potential environmental implications and safety considerations of nuclear desalination from many angles, this study finds that the opportunities given by nuclear desalination are vast and untapped. RO unit operation parameters data were collected (daily and hourly readings) for 8 months in 2017 covering all the process inputs and outputs such as flowrate, temperature, TDS (Total Dissolved Solids), pressure. etc. MINITAB software is used to apply the Six Sigma technique on the collected data. This improvement focuses on many points such as water quality, process components lifetime and power consumption. Furthermore, an RO simulator (TORAY DS2) is used to validate the results of DMAIC recommended settings for the RO unit to improve its performance and to prove that the Six Sigma recommended operation settings will extend the RO membrane lifespan.
