Abstract

A one-dimensional numerical model of the breakdown for a fluorine bubble due to break-up and chemical reactions with dissolved UF4 and PuF4 in the molten salt reactor (MSR) volatilization process was revised. The updated model utilized a more realistic, 1.0 cm F2 bubble to study the breakdown process in the idealized MSR fuel purification vessel. Although more accurate reaction interface and F2 reactivity values were used, chemical reactions were still found to be the primary cause of bubble breakdown. The importance of efficiency in F2 usage in the purification process on the economic and safety point of view was discussed.
