Fluid dynamics and heat transfer in an accelerator-driven subcritical fission core

Accelerator-driven subcritical fission in a molten salt core (ADSMS) is being developed as a technology for green nuclear power. ADSMS burns its fertile fuel to completion, it cannot melt down, and it destroys long-lived minor actinides. The ADSMS core consists of a vessel filled with a molten salt eutectic of UCl$_{3}$ and NaCl. Fission is driven by generating fast neutrons by spallation of energetic protons on spallation targets within the core. Fission heat is transferred from the molten salt to liquid Na in a primary heat exchanger located above the core. A conceptual design for the fluid dynamics and heat transfer in the core and in the heat exchanger will be presented.
