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.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

An experimental method of measuring parameters peculiar to a two-region nuclear reactor is developed requiring the measurement of the cross-power spectrum between the outputs of the two reactor regions when a random reactivity input is given to one of the regions. Using bandpass filters and an analog computer, the cross-power spectrum between the outputs of the two regions in the University of Florida Training Reactor has been measured. These data indicate that the propagation of a disturbance from one region of the reactor to the other region may adequately be described in terms of neutron-wave phenomena and that the method may be used to determine the multiplication factor of each region.
