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.

Delivering new nuclear on time, the first time
Mark Rinehart
The nuclear industry is entering a period of renewed urgency, driven by the need for stable baseload power, heightened energy security concerns, and expanded defense infrastructure. Now more than ever, we must deliver new nuclear projects on time and on budget to maintain public trust and industry momentum.
The importance of execution certainty cannot be overstated—public trust, industry investment, and future deployment all hinge on our ability to deliver these projects successfully. However, history has shown that cost overruns and schedule delays have eroded confidence in the industry’s ability to deliver nuclear construction. As we embark on many first-of-a-kind (FOAK) reactor builds, fuel cycle infrastructure projects, and extensive defense-related nuclear projects, we must ensure that execution certainty is no longer an aspiration—it is an expectation.

The characterization of lifetime-component capabilities of various chamber armors is a critical path to the development of the High Average Power Laser (HAPL) reactor design. Previous studies have examined tungsten as an armor material to protect the low-activation ferritic steel first wall from x-ray and ion damage.Carbon-bearing materials are of interest as candidate armor materials due to their desirable thermal and mechanical properties. This analysis examines and compares several carbon-bearing materials: silicon carbide, graphite, engineered graphitic materials and carbon nanotube composites.The transient thermal response of these materials was simulated with the BUCKY 1-D radiation hydrodynamics code utilizing the standardized HAPL x-ray and ion threat spectra. Evacuated and buffer gas filled bare-walled configurations were simulated.
