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.

The Spanish Technofusion project includes an irradiation laboratory equipped with two tandem-type accelerators (protons/deuterons and alphas) and a multi-ion cyclotron (heavy ions).A radioprotection issue concerning activation of the irradiated samples is to establish the required "cooling" waiting period for safe handling. Samples of iron, Al2O3, SiO2, and SiC are considered here.In dealing with this task, inventory calculations have been performed using, in addition to cross-section data available in different activation libraries, experimental data for some dominant reactions that have not yet been considered in the generation of the corresponding evaluated activation cross sections. Residual dose rate results, calculated from the radioactive inventory determined using both evaluated data alone and a combination of evaluated and experimental data, are compared and the impact of the results on handling limitations analyzed.Very affordable cooling times are found suitable for the irradiated samples. The calculated cooling times meeting safe handling requirements are expected to have high reliability for the proton beam in Al2O3 and the alpha beam in Fe and relatively high reliability for the proton beam in SiO2 and Fe as well as the alpha beam in Al2O3 and SiO2; only deuteron beam is satisfactory for Al2O3; and finally, for SiC, all cases are unsatisfactory.
