The NDDP is a hybrid plant, integrating both Multistage Flash (MSF) and Reverse Osmosis (RO) technologies. The MSF plant, with a capacity of 4500 cubic meters per day, utilises low-pressure steam from the MAPS. The RO plant contributes an additional 1800 cubic meters per day. This hybrid approach offers several advantages, including the use of cheaper construction materials for the MSF plant, careful control of seawater chemistry, and the blending of product water from both plants to achieve the desired water quality. Part of the high-purity water produced by the MSF plant is used as makeup demineralised water for the power station. The project has provided valuable experience in the design, installation, testing, and commissioning of nuclear desalination plants and has served as a demonstration facility, providing design inputs for larger-scale plants. While the existing plant is nearing the end of its designed lifespan, plans are underway to add new desalination units to meet increasing freshwater demands.
