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.
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.

Fast neutron radiography (FNR) has a great potential as a nondestructive technique for testing large objects. A FNR system developed based on a deuterium-tritium neutron generator is presented. Resolution of the FNR system is analyzed using the modulation transfer function (MTF). FNR experiments based on film and charge-coupled device imaging are carried out, respectively. The experimental results of image resolution are compared with the results of MTF calculation. Moreover, the impacts of various system components on signal degradation are discussed in this paper.
