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.

For the specific reactors evaluated in the Reactor Safety Study (WASH-1400), quantified uncertainties in the calculated consequences and probabilities were reported, along with median estimates. The WASH-1400 evaluation of early fatalities gave these uncertainties as multiplicative factors of (, 4) on consequences and (, 5) on probabilities. Accounting for factors that were not considered, these uncertainties are better stated as multiplicative factors of (, 15) and (, 20) for consequences and probabilities, respectively. In addition to this change in uncertainty, the median values of early fatalities reported in WASH-1400 may be too high by factors of 5 for consequences and 12 for probabilities. Thus, a new upper bound is found that is less than that stated in WASH-1400.
