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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Dual-beam ion irradiation with Si- or Si and He ions was used to simulate expected fusion conditions. Indentation techniques were used to determine the changes in hardness, modulus and indentation fracture toughness in dual-ion irradiated -SiC at temperatures range from 673 to 1673 K. Ion irradiation clearly enhanced radiation induced hardening. Also, appreciable hardening by simultaneous helium injection revealed after dual-ion irradiation. The elastic modulus of the ion irradiated -SiC exhibited a slight decrease at low temperature irradiation, and a recovery at high temperature irradiated -SiC. The indentation fracture toughness increased after both single- and dual-ion irradiation for dose up to 1-3 dpa, then decreased for higher temperature and longer irradiation.
