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.

Offshore nuclear power concept under development by BWXT and Crowley
BWX Technologies is teaming with Crowley, a global shipping and energy supply chain company, under a memorandum of understanding to develop a ship with an onboard microreactor that could deliver power to users on shore via buoyed power cables. The concept, announced by both companies on September 20, is envisioned as a zero-carbon energy option for defense and disaster needs.
