Russia's Smolensk NPP begins loading improved nuclear fuel

On September 1, 2026, local time, Unit 1 of Russia's Smolensk Nuclear Power Plant began gradually loading improved nuclear fuel. The fuel assemblies feature adjusted uranium-235 enrichment and erbium oxide content, as part of the RBMK-1000 reactor modernization program aimed at enhancing unit operational safety and efficiency. The Smolensk NPP is part of the electric power division of Rosatom and is operated by Rosenergoatom. The fuel assemblies loaded into the core this time use lower uranium-235 enrichment and lower erbium oxide content. According to relevant calculations, the new fuel can compensate for changes in core neutronics parameters following graphite stack repair...
