The System Analysis and Integration Campaign (SA&I) was tasked to perform a quick turnaround study to estimate the number of potential new sites having a capacity of 600 MWe or greater that could be situated on currently operating and recently retired coal power plant (CPP) sites and current nuclear power plant (NPP) sites. The analysis of the CPP sites was performed by updating the operational status of coal plants as of April 2024 and building on the data from the coal-to-nuclear (C2N) study completed in 2022 by Hansen et al. (INL/RPT-22-67964-Rev000) using the Oak Ridge Siting Analysis for power Generation Expansion (OR-SAGE) tool. Current NPP sites with cancelled plans for additional units during initial site construction were evaluated, as well as sites that have initiated the process to obtain a combined construction and operating license (COL) to build new NPPs. Operating NPP sites that did not fit this profile and recently retired NPPs were also evaluated using subjective analysis based on knowledge of the site footprints (acreage), aerial analysis, and OR-SAGE visual parameter evaluation to estimate the viability of adding new NPPs at existing nuclear sites.
