Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

This paper describes the recent progress of the HL-2A project. HL-2A is the first tokamak with divertor in China. The main parameters of HL-2A are major radius, R = 1.64 m; minor radius, r = 0.38 m; toroidal field, Bt = 2.8 T; plasma current, Ip = 480 kA; and current flattop time, t = 2 to 5 s. Subjects related to the divertor, confinement, magnetohydrodynamic (MHD) instabilities, heating and current drive, fueling, etc., will be investigated with HL-2A. Significant progress in the construction of the HL-2A tokamak has been achieved recently. This paper describes the development of major components and the installation of the machine. The commissioning of the HL-2A machine will begin in the middle of 2002. The HL-2A physics research program has been proposed and will emphasize the divertor, MHD instabilities, and confinement.
