21st International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems, ECOS 2008, Cracow-Gliwice, Polonya, 24 - 27 Haziran 2008, ss.1375-1384
In this study an attempt has been presented to facilitate the optimization of a new proposed Thorium Molten-Salt Nuclear Energy Synergetic System (THORIMS-NES) with a thermodynamic analysis based on exergy. THORIMS-NES is a symbiotic system which is based on the Thorium-Uranium-233 cycle. The energy is produced in molten salt reactors (MSR:FUJI) in which the fuel is uranium fluoride UF4 dissolved in a mixture of 7LiF and BeF2. Fissile 233U is produced by spallation in Accelerator Molten-Salt Breeders (AMSB). An elementary strategy for optimization procedure of the proposed system THORIMS-NES has been outlined from the point of view of exergy. Exergy analysis of thorium breeding fuel cycle is considered in three parts: molten-salt breeders producing fissile isotope 233U, molten-salt nuclear reactors itself and subsequent streams in the nuclear energy system. Major exergy releases associated with nuclear reactions are in breeder and reactor. Since major exergy releases associated with nuclear reactions are in breeder and reactor, MSR itself has the greatest potential to improve the plant efficiency.
