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.

The total neutron cross sections of sodium and potassium have been measured for neutron energies from 0.9 Mev to 1.7 Mev at intervals of 5 kev, with an energy resolution of about 5 kev. Total cross sections of sodium, potassium, and calcium have been measured at intervals of 50 kev from 1.25 Mev to 2.1 Mev, using an energy resolution of about 65 to 75 kev. A neutron time-of-flight method was used in both sets of measurements.
