Reproduction dataset and screening workbook for regional small modular reactor screening in Greece after lignite

This dataset provides the inputs, code, outputs, provenance and a human readable workbook that regenerate every composite score and sensitivity result reported in the associated article, titled Reactor size and host system eligibility in regional small modular reactor screening for Greece after lignite. The study builds a transparent two stage screen for five Greek regional cases, namely Western Macedonia, Eastern Macedonia and Thrace, Central Macedonia, Crete and a Dodecanese large island proxy, across three reference reactor tiers of about 300, 30 and 5 MWe. Stage 1 applies rule based exclusions on protected areas, archaeological constraints, tsunami exposure, fault proximity, exposed population, ultimate heat sink adequacy and host system absorption. Stage 2 applies a weighted sum model over five ordinal criteria, namely seismic characterization, population exposure, ultimate heat sink adequacy, grid readiness and strategic transition rationale, with a declared weight vector of 0.42, 0.16, 0.26, 0.10 and 0.06. The archive contains three input tables in the inputs folder, two Python scripts in the code folder, the regenerated result tables in the outputs folder, a parameter provenance file, a license, a README, and the file Supplementary_Workbook.xlsx. The workbook mirrors every input, output and sensitivity table across its tabs so that the same numbers can be inspected without running the code, and all stored values are literal, so they display in any spreadsheet viewer without recalculation. The robustness material covers Dirichlet weight sampling, one at a time perturbation with renormalization, a PROMETHEE II outranking check, an equal weights scenario, a monotone rescaling of the ordinal levels, and a seismic recoding and scaling check.
