Erratum: Corrigendum to “Coupled thermochemical, isotopic evolution and heat transfer simulations in highly irradiated UO₂ nuclear fuel” (Journal of Nuclear Materials (2013) 441(1–3) (240–251) (S0022311513008064) (10.1016/j.jnucmat.2013.05.060))

Figs. 7–9 in “Coupled thermochemical, isotopic evolution and heat transfer simulations in highly irradiated UO₂ nuclear fuel” [1] have a consistent error corresponding to the relative proportions of iodine. Reported concentrations of iodine in the original manuscript are approximately ten times higher than expected, and are comparable in atomic proportions to cesium. One would expect that the amount of cesium would be about one order of magnitude greater than iodine based on the difference in fission yields of ²³⁵U and ²³⁹Pu. A practical consequence of this error would affect the predicted quantity and chemical composition of iodine on the fuel surface, which is related to iodine-induced stress corrosion cracking [2]. The authors have confirmed that the source of the error was not rooted in any of the models or in the computer programming, but was instead a simple plotting error. This has been verified by an independent analysis [3] and an additional independent verification. Therefore, all other results and figures in the original text are correct. Revised copies of Figs. 7–9 are provided below. As an additional source of discrepancy between the simulated and experimental results, the authors point to the delay between irradiation and post-irradiation examination measurements, which was not defined in the experimental paper by Walker et al. [4]. The following figures compare predicted elemental distributions in highly irradiated UO₂ fuel at various radial positions with respect to Electron Probe Micro-Analysis (EPMA) measurements performed by Walker et al. [4].
