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.

Elementary school resources added to Navigating Nuclear
Elementary school lesson plans are the latest additions to the Navigating Nuclear: Energizing Our World website. The two lesson plans were created to help students in grades 3-5 understand the power of the atom and how to investigate different energy sources.
Navigating Nuclear is a K-12 nuclear science and energy curriculum created in partnership by the American Nuclear Society and Discovery Education, with lead funding from the Department of Energy's Office of Nuclear Energy.

Calculations and measurements are presented for direct capacitor charging from tritiated electrodes, efficiency in converting beta decay energy into electric current, the effect of geometry on charging current, and the dielectric engineering options/trade-offs. Experiments using 1.4 × 1012 Bq (38 Ci) of tritium provided a 148-nA short circuit (charging) current at 5300 V of open circuit voltage, giving 160-W peak electrical power, with 12.5% overall efficiency. Calculations are in good agreement with the measured voltage accumulated over time for the tritium capacitor.
