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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Recent progress made at LLNL on fabricating NIF scale polyimide capsules using vapor deposition techniques is detailed. Our major focus has been on improving the capsule surf ace finish through better understanding of the origin of surface roughness created during the deposition process and implementation of a post-deposition vapor smoothing procedure prior to imidization. We have determined that the most important factors during the deposition process that impact surface finish include mandrel quality, monomer mixing, selfshadowing, and abrasion. We have shown that high rate deposition (above 10 μm/h) is effective at reducing roughness, which we believe is due to the shorter total time of shell agitation in the bouncer pan. By adjusting the coating conditions, coatings up to 160 μm thick have been reproduc-My fabricated with 300 nm RMS roughness. Solvent vapor smoothing, a new technique also developed at LLNL, further improves the surface to 30 nm RMS.
