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.

An essential support system of the Compact Ignition Tokamak (CIT) is the Vacuum Vessel Heating/Cooling (H/C) System. The requirement for the design of the dual function H/C System is to initially provide sufficient input heat energy to raise the temperature of the vacuum vessel from a 21°C ambient temperature to the operating temperature of 340±10°C and subsequently provide sufficient heat removal capacity to limit the cooling period between plasma pulses to 1 hour. The H/C System currently proposed for the CIT vacuum vessel accomplishes both of these system objectives using a single gaseous helium system flowing through a series of ducts attached to the exterior surface of the vacuum vessel shell. The design requirements, duct arrangements, and design analyses for the preliminary H/C System design are identified.
