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 age of U235 fission neutrons to indium resonance energy has been measured in a number of lattices of Th-H2O and Th-Al-H2O and compared with theoretical calculations. As a check on the procedure similar measurements were made in pure water yielding a result of 27.0 ± 0.9 cm2. In addition, the ratio of the age of U233 fission neutrons to the age of U235 fission neutrons in water was found to be 0.948 ± 0.033.
