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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

At the Ningyo-Toge Environmental Engineering Center, technical developments related to uranium refining conversion and enrichment have been completed and decommissioning of these facilities has begun. The error between the quantity of dismantled materials estimated from the facility design drawings and the actual quantity of the dismantled materials was about 1.7% when averaged over the entire facilities already dismantled. Most of the dismantled materials, which have no contamination history and were properly managed, were confirmed to have surface radioactivity concentrations below the detection limit and could be carried out to recyclers as nonradioactive (NR) waste. The dismantled materials that could not be certified as NR needed to be cleared and reused. By evaluating two types of gamma rays of 234mPa from the mockup dismantled objects, it was found that uranium corresponding to a clearance level (1.2 × 102 Bq/kg) could be quantified.
