b'2020DOME and LOTUS Test BedsThe iconic Experimental Breeder Reactor-II containment dome at the Materials and Fuels Complex began its transformation into a test bed for advanced microreactor demonstrations. The repurposed facilityknown as the Demonstration of Microreactor Experiments, or DOME, Test Bedwill host microreactors with thermal power ratings of up to 20 megawatts. Nearby, the Laboratory for Operation and Testing in the U.S. (LOTUS) has been established in the former Zero Power Physics Reactor cell to provide a home for the Molten Chloride Reactor Experiment, the worlds first test of a fast-spectrum, molten salt-fueled reactor design. 75'
