It is shown that in normal operation and in modes of deviations from normal conditions, the DSFSF system with WWER-WR remains within the temperature limits provided by the design. The maximum cladding temperature of the WWR fuel rod cladding in normal operation modes in the DSFSF system does not exceed 350 ºС. Despite the conservatism in the calculation of the SFA temperature condition, there is a margin for the maximum cladding temperature of the WWER-WR fuel assemblies, which, if necessary, can be used to increase the residual power of the fuel assemblies to be loaded and reduce their spent fuel assembly holding time in the spent fuel assemblies. The optimal geometric parameters of SFAs made of uranium-containing materials in different physical forms were evaluated for manufacturing working reference samples on their basis. The design of a container for packaging reference samples of uranium-containing materials was determined and design documentation for containers for packaging working reference samples was developed. Uranium dioxide-based SFPs were produced by mechanical mixing of powders with enrichment of 235U 0.4 and 19.7 %. The methodology for measuring the elemental composition of the experimental batch of uranium dioxide fuel pellets for the experimental fuel assembly TVZ-X, which was designed to be compatible and to replace the TVZ VVR-M2 in the nuclear facility "Electron Accelerator Controlled Neutron Source", was tested.
