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 most pressurized water reactors, moderator temperature coefficients (MTCs) must be measured at end-of-cycle conditions at power to verify that Technical Specification limits on negative MTC will not be violated. Three techniques for performing these measurements are evaluated, and the relative strengths and weaknesses of each method are discussed. Considering overall accuracy and time required to perform the test, a best method is selected, and its accuracy is compared with previous measurements performed at Davis-Besse Unit 1, thus demonstrating the effectiveness of this technique. In addition, the necessity of attempting to perform this measurement at power at end-of-life conditions is discussed.
