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.

Nuclear supply chain innovation and collaboration: Keeping the nuclear supply chain viable through change
The next nuclear renaissance may be upon us, but with it comes a perfect storm. The industry is unprepared for a surge in demand for goods and services from both the existing light water fleet and the next generation of reactors. We are currently teetering on the edge of severe supply chain issues, but if the nuclear industry can understand the sources of our challenges, we can mitigate them.

The real advantage of the laser driver as compared to other drivers is its ability to provide a high quality focal spot on target. Heat generation in solid-state media has always been recognized as a limiting feature because at high repetition rate, the quality of this focal spot depends on the beam wave-front distortions. It is not easy to design the driver baseline because there are too many different parameters to deal with. In this paper, we introduce two figures of merit that show that Yb doped ceramics (either garnets or sesquioxides) are promising laser materials opening new fields during the research phase to demonstrate ignition and fusion gain (including the fast ignitor concept). When driven at low temperature (cryogenic cooling), all of the operational features of the laser amplifier can be demonstrated at an aperture scale of only 10-15 cm.
