Idaho National Laboratory Demonstration nuclear power plant
Idaho National Laboratory Demonstration nuclear power plant is a gas-cooled reactor unit at Idaho National Laboratory Demonstration nuclear power plant in United States rated at 15 MW gross. It is cancelled (a status Global Energy Monitor inferred from an absence of observed progress).

This unit runs on natural uranium, so its fuel chain has no enrichment step at all: mine → mill → conversion → fabrication. That is the shortest fuel chain of any commercial reactor type, and it makes the operator independent of the four organisations that control enrichment worldwide.
