Small modular reactor market-readiness master dataset from Nuclear Energy Agency SMR Dashboard Editions 1–3

This dataset contains the harmonised small modular reactor market-readiness master dataset reconstructed from the first three editions of the Nuclear Energy Agency Small Modular Reactor Dashboard. It includes design-level information, dashboard source links, market-readiness indicators, technology characteristics, regional classifications and sample-classification fields used in the study “From pipeline growth to first-of-a-kind deployment: market readiness across the global small modular reactor landscape”. The workbook documents the analytical dataset and audit trail used to support the longitudinal and cross-sectional analyses. Figure-specific source-data files and reproducible code are archived separately in the associated GitHub repository.
