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.

First GAIN vouchers of 2025 go to Curio, Deep Fission, Kairos, and NuCube Energy
The Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) has awarded four fiscal year 2025 vouchers to support the development of advanced nuclear technologies. Each company will get access to specific capabilities and expertise in the DOE’s national laboratory complex—in this round of awards both Idaho National Laboratory and Pacific Northwest National Laboratory are named—and will be responsible for a minimum 20 percent cost share, which can be an in-kind contribution.

A mechanistic model is presented to predict the steam condensation on containment finned tubes in the presence of noncondensables (NCs). The total thermal resistance from bulk gas to coolant is formulated as a parallel combination of the convective and condensation gas resistances coupled in series to those of the condensate layer, the wall, and the coolant.The condensate layer thermal resistance is calculated by means of an Adamek-based model, while the gas mixture thermal resistance is formulated based on diffusion layer modeling.The model results are compared with the available experimental data of Wanniarachi and Rose for pure steam condensation on finned tubes and with the data of Mazzochi for condensation in the presence of NC gases.
