Every thermal and structural analysis in the MetroVolt series draws on a curated extraction of the ITER Material Properties Handbook: 4,744 unflagged measured data points across 35 materials, shipped inside the open deposit.
Reactor design fails quietly when material properties are single-number assumptions. The deposited basis carries per-point scatter for the properties that matter — thermal conductivity, yield strength, mean thermal expansion — with data-quality flags honored and an n > 2 rule per property curve. The plasma-facing and structural analyses (KX-3/KX-4 class) run on those measured curves directly.
The vessel material itself — a CrMoNbV high-entropy-alloy class — is carried against an explicit ≈36-dpa capability qualification target at the design dose: a stated materials-programme requirement, cleanly separated from the demonstrated database that everything else runs on.
Due diligence teams ask one question of every engineering claim: against what data? MetroVolt's answer is a folder in the deposit. Measured scatter in, honest margins out — and the one place the design leans on future qualification is labeled as exactly that.
