Modeling Molten Salt Spreading and Heat Transfer using MELTSPREAD – Model Development Updates

Abstract

is a U.S. Department of Energy laboratory managed by UChicago Argonne, LLC under contract DE-AC02-06CH11357. The Laboratory's main facility is outside Chicago, at 9700 South Cass Avenue, Argonne, Illinois 60439. For information about Argonne and its pioneering science and technology programs, see www.anl.gov. DOCUMENT AVAILABILITY Online Access: U.S. Department of Energy (DOE) reports produced after 1991 and a growing number of pre-1991 documents are available free at OSTI.GOV (http://www.osti.gov/), a service of the US Dept. of Energy's Office of Scientific and Technical Information.

Regulatory Considerations Regarding Potential High Temperature Fluid Releases in Advanced Reactor Designs

“…The MELTSPREAD code developed for the analysis of exvessel molten fuel progression for LWRs has some applicability to salt spills for fuel salt MSRs [105]. Although some preliminary salt spill experiments have also been performed by Argonne National Laboratory [106,107], the existing experimental data base is limited.…”

State of Knowledge on Aerosols and Bubble Transport for Mechanistic Source Term Analysis of Molten Salt Reactors

“…This is likely an inert, closed atmosphere. Although the temperature of the salt may increase for some period of time due to decay heat [79], the salt will eventually cool over time due to a reduction in radioactivity or via active cooling. Therefore, barring any reactivity insertions, radiolytic effects of the salt will become more important as the salt temperature decreases below a certain point.…”
