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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The 3 GJ target with low repetition rate and thick liquid wall chamber presents the mainline choice for the Z-Pinch power plant. An engineering scoping assessment has been developed for two candidate breeders (Flibe (F4Li2Be)molten salt and Li17Pb83 liquid metal) to identify the design requirements and optimize the components' dimensions. Several important engineering features have been incorporated to improve the Z-Pinch performance. For instance, an advanced high-temperature steel-based structure could operate near 800°C, an advanced power cycle could achieve high thermal conversion efficiency approaching 50%, a low-activation F82H-based steel with controlled impurities will generate only low-level waste, and an innovative idea has been developed to establish jet flow using a sluice valve. This paper identifies self-consistent reference parameters and documents an interesting comparison between the candidate breeders, highlighting the fundamental differences in performance and the benefits and drawbacks of each breeder.
