Water Integration in Thermoelectric plants: the Collected Dataset

When addressing water scarcity in thermoelectric plants, most research focuses on the cooling system. Water-savings at the plant-wide scale through water reuse and recycling remain unexplored. The potential of Water Integration methods to identify acceptable valorisation strategies for real-case scenario in French nuclear power plants have not been explored yet. However, early-stage studies are often challenged by a high lack of knowledge. In this case, no systemic schemes or indicators of the existing water network were available prior to the study, and characterization of streams in terms of both quantity and quality was limited. In this context, we share a dataset representative of French thermoelectric plants water network that aims to be applied to Water Integration methods. The dataset is given by Table 1 in the attached PDF file. A French nuclear power plant is used as reference. It presents a selection of 8 sinks and 4 internal sources sources. Fixed flowrate for each stream was sourced from industrial design datasheets while quality indicators (i.e., concentrations, properties and mass load limits) were extracted from industrial operational requirements and regulatory limits on discharges imposed by local authorities. Two external water sources were considered. Demineralized water (DW) and filtered river water (RW). Their composition is defined from average annual measurements when available or recovered from on-site chemical specifications. The collected dataset provides the basis to evaluate the relevance of Water Integration to explore water valorisation pathways in a thermoelectric setting. The given dataset will be updated with further parameters to consider additional constraints, such as schedules, localisation and space constraints.
