Abstract: Replication data for the paper First-Wall Thermomechanics and Fatigue Life of Plasma-Facing Components Under Combined Surface and Volumetric Loading in a Compact Spherical-Tokamak Breeder (Kronos Fusion Energy 2026 Publication Series, paper 2.43), published at doi:10.5281/zenodo.22645850. Abstract of the paper. The plasma-facing components (PFCs) of a compact breeder live simultaneously inside a hard 14 MeV neutron field, a cyclic surface heat load, and a demount–remate maintenance duty; the engineering question is not whether the wall is loaded but which mechanism sets its life. We pose the coupled thermomechanical, radiation-damage and fatigue problem for the Hyperion breeder at its frozen design point (P_ fus=85.04 MW, I_p=9.66 MA, Q=3.076, negative triangularity δ=-0.30, first-wall neutron loading _ w=1.885 MW m^-2) and solve each failure mode from its governing equations. We write the conjugate heat-transfer problem with a combined Neumann surface flux and a volumetric nuclear source and a Robin coolant condition; the thermoelastic stress from constrained thermal expansion; the Norgett–Robinson–Torrens (NRT) and athermal-recombination-corrected displacement model folded against the primary-knock-on spectrum; helium-bubble rate theory closed by a van der Waals equation of state; and the Coffin–Manson–Basquin strain–life law with Palmgren–Miner accumulation. Solved on the NVIDIA GPU high-performance-computing (HPC) campaign with OpenMC/DAGMC transport-and-depletion, LAMMPS molecular-dynamics cascades, RustBCA binary-collision sputtering, and a finite-element conjugate-heat-transfer solver, the results are unambiguous. What this dataset contains data/key_values.csv and data/anchors.json: the frozen design-point values quoted in the paper (symbol, value, unit, provenance), in machine-readable form. data/verification.csv: the validator gates the paper cites, each with its verdict and a link to a live recompute page. figures/: the figures from the paper, as vector PDF, with an inventory. first-wall-thermomechanics-and-fatigue-life-of-plasma-f.data-methods.pdf: methods, the computational codes used, and the full value table. data/data_dictionary.md: column definitions. Every value is a frozen design-point number that is independently re-run and recorded in the Kronos Physics De-Risking Register (doi:10.5281/zenodo.22645689).
