Nuclear Waste to Electric Power

The Wielenga Innovation Foundation, Inc. supports the development of technology that converts nuclear waste to a molten salt that can be "burned" in nuclear reactor.  We aim to eliminate the waste disposal problem and generate massive amounts of electricty. We call it the "Fast Salt" system because the fuel is molten salt suitable for a "fast spectrum" reactor.  A reactor developed by the Wielenga Foundation burns the long lived portion of waste in conventional reactors that make the waste remain radioactive so long and disposal of it problematic.  We call this reactor the "Wielenga Innovation Salt Tank Reactor" (WISTR).  This reactor was developed in conjunction with researchers at the University of Michigan.  The reactor is a low-pressure, fast spectrum, waste burning reactor.  It burns long lived transuranic (TRU) elements recovered from spent light water reactor (LWR) fuels.  It is sized to provide 600 MW electric power. The core is compact and easily manufactued. 

Here is a presentation on the "Fast Salt System" that gives an overview of the system.  This was presented at the MSR Workshop in Knoxville, TN on 11/19/2025.

The WISTR has undergone extensive analysis and development.  A review of the development is a University of Michigan Nuclear Engineering and Radiollogical Sciences department report:  Core Design Evolution of Wielenga Innovation Salt Tank Reactor (WISTR), Yang, W.S; Lee, H; Willat, R; Wielenga T.
