Transient energy transfer by conduction and radiation for a sudden contact between molten UO/sub 2/ and sodium
The transient energy transfer following a sudden contact between molten UO/sub 2/ and sodium has been investigated, taking into consideration both conduction and internal thermal radiation in UO/sub 2/. Analytical expressions for the contact-interface temperature valid for small times are derived. Illustrative calculations indicate that on a time scale relevant to fuel-coolant interactions, internal radiation of molten UO/sub 2/ should have an insignificant effect on the contact-interface temperature between molten UO/sub 2/ and sodium. It thus appears that for the purpose of assessing the potential for an explosive fuel-coolant interaction, the contact-interface temperature may be adequately determined based on consideration of pure conduction.
