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.

In this paper, we describe recent measurements with the ASDEX Upgrade two-color CO2/HeNe interferometer in which a time resolution of 200 ns was obtained in the density measurement by digitizing the 40-MHz raw signals of the interferometer at 500 million samples/s and performing density reconstruction by software. It is illustrated that this high resolution is beneficial during massive gas injection for disruption mitigation, as it allows for the discovery of fast density oscillations in the frequency range from 200 kHz to [approximately]1 MHz, which shows clear correlation to magnetic measurements.
