ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

Subcritical multiplication constants have been derived from pulsed-neutron measurements for 2×3 square pitch and hexagonal arrays of massive hollow cylinders of uranium-aluminum alloy in H2O. The cylinders were 22.02-cm-o.d., 14.80-cm-i.d. bare 235U-Al alloy castings of 30.50 wt% uranium (76.97% 235U) in aluminum. These measurements extend previous benchmark experiments on similar castings with lower enrichments. KENO-IV, a multigroup Monte Carlo criticality code (with Hansen-Roach cross sections), calculates the subcritical multiplication constants for these lattices over the reactivity range 0.77 < keff < 0.98, with an average conservative bias of ∼0.005 in keff.
