College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

An adaptive controller is proposed to replace the current conventional controller in the plasma density feedback system at Joint European Torus (JET). Changing plant dynamics calls for matching retuning of the controller to retain the required performance of the control system. This controller tuning must now be done manually. In the adaptive controller, the retuning process is automated and runs in parallel with the control function. The plant is analyzed, the components of the proposed controller are designed to suit prescribed performance, and the result is illustrated in simulations.
