Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

This paper discusses the estimation of heat transfer characteristics using different SiO2 nanofluid conditions on a downward-facing heating surface. Two sizes of SiO2 nanoparticles (20 and 50 nm) were selected for the nanofluids. The influence of the critical heat flux (CHF) for different nanofluid concentrations was also compared and investigated. We observed that the CHF changed with the concentration of nanofluids, which reached the maximum enhancement at 0.1 g/L but decreased at 0.12 g/L. Compared with reverse osmosis water, the 50- and 20-nm SiO2 nanofluids exhibited enhancements of approximately 43% and 49%, respectively. The heating surface was characterized and the deposition of nanoparticles was observed. After pool boiling, the wettability of the heating block and the roughness changed. As the concentration increased, the CHF decreased after attaining the maximum value, which was due to the characteristics of the downward-facing heating surface and the decrease in the nucleation points on the heating block surface.
