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.

A new method to diagnose the degree of electron degeneracy in compressed fuel for fast-ignition inertial confinement fusion is proposed. We focus on 4.44-MeV -rays emitted in the reaction 9Be(,n)12C governed by fusion-produced energetic alpha-particles in a laser-imploded DT fuel pellet admixed with a small amount of 9B. In this case the compressed fuel pellet is not subjected to any heating laser pulse. We have evaluated the probability P-Be that the + 9Be reaction occurs during the slowing down of -particle. It is found that the reaction probability depends strongly on the degeneracy parameter , which is defined as the ratio of electron temperature to the Fermi energy. We show the possibility of diagnosing the electron degeneracy from the P-Be - diagram by detecting the 4.44-MeV -quanta and DT neutrons emitted from the dense core plasma.
