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.

A straightforward numerical-graphical method is applied to achieve a flat fission power density (FPD) in a catalyzed deuterium-deuterium fusion-driven hybrid blanket by using a mixed fuel made of a nuclear waste actinide (244CmCO2) and natural UO2 with variable fractions of fuel components in the radial direction. The FPD could be kept quasi-constant over a relatively long plant lifetime. The peak-to-average FPD increases from 1.071 at start-up to ∼ 1.074 after 18 months’ operation. The plant availability factor is 60% under a first-wall fusion neutron flux load of 1014 x 2.45- and 1014 x 14.1-MeV neutron/cm2.s, corresponding to ∼2.64 MW/m2. This eliminates the fuel management requirements for at least 18 months of plant operation. The investigated blanket breeds high-quality nuclear fuel (239Pu and 245Cm) and also produces electricity. The overall blanket multiplication factor M increases from 9.4 to only 9.8 in 18 months. This allows an optimal exploitation of the nonnuclear part of the power plant.
