Abstract
According to the analysis of the nuclear fuel cycle (NFC) for a two-unit NPP, based on supercritical water-cooled reactors (SCWRs), the priority option for three aggregated criteria includes the start-up of the reactor using mixed uranium-plutonium oxide fuel and processing of spent fuel assemblies (FAs) after 7 years of internal storage. The backup option involves the operation of the reactor using uranium oxide fuel for 10 years followed by a phased transition to full core loading with mixed uranium-plutonium oxide fuel. The results of the performed analysis can be used to enhance the efficiency of design solutions for SCWR NPPs, as well as to assess the NFCs of a two-component nuclear power system with SCWR NPPs, including uranium-plutonium and thorium-uranium NFCs and/or their combinations.
