Abstract
Nuclear desalination has positioned itself as a reliable and cost-effective means of producing potable water, and small modular reactors (SMRs) are reportedly ideal for desalination purposes. This work investigated the thermal coupling of the NuScale reactor, a 50 MWe SMR, and a direct contact membrane distillation (DCMD) desalination plant with heat recovery and feed recycle. Both the waste heat and the low pressure (LP) steam extractions from the reactor turbine were assessed as energy sources for desalination. Longer DCMD modules presented higher values of gain to output ratio (GOR), indicating higher thermal efficiency and, thus, higher distilled water production. The LP steam extractions were not only capable of boosting the distilled water production of the desalination plant, but also highly reduced the total membrane area necessary for desalination. The proposed coupling schemes were able to produce up to 5,429 m³/d of distilled water.
