Dataset for Er₂O₃ Discrete Burnable Absorber Neutronic Analysis in a TVSA-12-Type VVER-1200 Fuel Assembly

This dataset contains OpenMC XML files, depletion outputs including .h5 files, statepoint files, processed results, and supporting data used in the neutronic evaluation of Er₂O₃ discrete burnable absorber rods in a TVSA-12-type VVER-1200 fuel assembly. The repository supports reproduction of the calculations, figures, and tables presented in the associated manuscript.
