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.”

Neutron total cross sections of 60Ni were measured with broad resolutions from ∼0.5 to 5.0 MeV at intervals of ≲50 keV. Differential elastic neutron scattering cross sections were measured from 1.5 to 4.0 MeV at intervals of ≲50 keV over the scattered neutron angular range from ∼20 to 160 deg. Differential cross sections for the inelastic neutron excitation of states at 1.342 ± 0.013, 2.168 ± 0.010, 2.304 ± 0.026, 2.509 ± 0.022, 2.636 ± 0.019, and 3.164 ± 0.041 MeV were also measured. The experimental results are interpreted in terms of optical-statistical and coupled-channel models, including consideration of compound nucleus fluctuations and direct-vibrational processes.
