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 problem of critical dimensions of an infinite-slab multi-layer multiplying system can be solved by a general procedure due to K. M. Case. The angular neutron distribution and the critical core size can then be found by solving the Fredholmtype integral equation with an additional critical condition. Numerical calculations have been done for the case of a multiplying slab surrounded by an infinite reflector, assuming one-energy group and isotropic scattering of neutrons, the mean number of secondary neutrons per collision in a medium-c being a variable parameter. Various approximations of the exact solution have been compared and the asymptotic theory has been found applicable in a wide range of c values in both media. 272
