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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

A numerical analysis has been performed to study the mass transfer characteristics of the chemical addition system for a nuclear power plant. The transient concentration profile of the chemical additives and the required time to inject the additives from the chemical injection tank have been investigated using a low Reynolds number turbulence model. Calculations were also performed with a disk placed at various locations along the centerline of the chemical injection tank to investigate the amount of reduction in injection time and to propose an optimal design of the chemical injection tank.
