The Thorium Molten-Salt Nuclear Energy Synergetic System [THORIMS-NES], described here is a symbiotic system, based on the Thorium-Uranium-233 cycle. The production of trans-uranium elements is essentially absent in Th-U system, giving nuclear proliferation resistance. The energy is produced in molten salt reactors (FUJI) and fissile 233U is produced by spallation in an Accelerator Molten-Salt Breeders (AMSB). This system uses the multifunctional “single-phase molten-fluoride” circulation system for all operations. There are no difficulties relating to “radiation-damage”, “heat-removal” and “chemical processing” owing to the simple “idealistic ionic liquid” character of the fuel. FUJI is size-flexible, and can use all kinds of fissile material achieving a nearly fuel self-sustaining condition without a continuous chemical processing of fuel salt and without core-graphite replacement for the life of the reactor. The AMSB is based on a single-fluid molten-salt target/blanket concept. Several AMSBs can be accommodated in regional centers for the production of fissile 233U, with batch chemical processing, including radio-waste management. FUJI reactor and the AMSB can also be used for the transmutation of long-lived radioactive elements in the wastes, and has a high potential for producing hydrogen-fuel in molten salt reactors. The development and launching of THORIMS-NES requires the following three programs during the next three decades: (A) pilot plant: miniFUJI (7-10 MWe): (B) small power reactor: FUJI-Pu (100-300MWe). (C) fissile producer: AMSB for globally deploying THORIMS-NES
