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.

Possible applications of an adaptive control method to a pressurized water reactor nuclear power plant are investigated. A self-tuning control algorithm with the generalized minimum variance strategy is employed. The control system design is based on a second-order linear model with unknown, time-varying parameters. To ensure that this low-order model describes the complex “real” dynamics well enough for control purposes, control parameters are updated on line with a recursive estimation sequence based on an extended least-squares method. The average coolant temperature is held as close as possible to a desired (but changing) reference value in the load-following mode of operation. The control rod position is selected as the control variable. Simulation results for such a system are encouraging and demonstrate the possibility of using this adaptive control method in an actual plant.
