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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

General Atomics (GA) is developing a new nuclear concept called Energy Multiplier Module (EM2), which is a helium (He) cooled fast reactor with a net electrical output of 240 MW. It employs a “convert & burn” core design which converts fertile to fissile and burns it in situ over a 30-year core life. It can burn SNF from LWRs with no reprocessing, only refabrication. The core can be recycled using an AIROX-based method to remove a fraction of the fission products (FPs) but no heavy metals. The reactor is passively safe and sited below grade. It can sustain a Fukushima type station blackout or even a station blackout combined with a loss of coolant accident using only passive safety systems without radioactivity release or loss of plant. The afterheat is rejected directly to the air. It is a high temperature reactor and employs a direct closed-cycle gas turbine for 48% net efficiency. The reject heat can be released directly to air so that siting near a large water source is not required. GA is targeting a power cost in the range of 6-7 cents/kW-hr, which would make it a competitive power source even with low-cost natural gas. This ambitious power cost is achieved through high efficiency, simplicity of the direct cycle gas turbine power and relatively small subsystems that can be shop fabricated and shipped by road to the site.
