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.

Dragonfly, a Pu-fueled drone heading to Titan, gets key NASA approval
Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.
On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

Taiwan’s Maanshan Nuclear Power Station (MNPS) consists of two pressurized water reactors [2775 MW(thermal)]. The reracking method has received licensing approval and has been successfully implemented by the Taiwan Power Company for MNPS to increase the spent-fuel storage capacity of each unit from 746 to 2160 fuel assemblies. MNPS is the only nuclear power station in the world that can store the accumulated spent-fuel assemblies from 40 yr of plant life in its on-site spent-fuel pool after reracking. The safety concerns regarding various aspects of this reracking project are presented. These safety concerns include thermal hydraulics, criticality, structure, radiation, and heavy loads.
