Molten Salt Reactor Salt Processing – Technology Status
This report presents a summary of 752 citations related to molten salt reactor development at Oak Ridge National Laboratory (ORNL). This effort was initiated with a focused purpose of locating technical information related to the chemical processing of fluoride salts to support the Th-232/U-233 fuel-cycle molten-salt breeder reactor. However, it soon became apparent that technical information on chemical processing was spread throughout numerous reports spanning decades of time. Therefore, the search effort was broadened to include any information deemed relevant to MSR development at ORNL. In addition, this report provides an overview of the engineering requirements of a chemical processing plant to support the Th-232/U-233 fuel-cycle molten salt breeder reactor (MSBR). This includes descriptions of the unit operations and flowsheets development at ORNL. The transition from the two-fluid MSBR to the single-fluid MSBR was largely due to the development of new separations technologies for the management of uranium, protactinium, and fission products in fluoride molten salts. The development and refinement of chemical processing plant flowsheets continued throughout the entirety of the MSBR program at ORNL. A great deal of experimental and theoretical work was performed in support of the unit operations and flowsheets described here.
