Oklo Inc. proposes to construct and operate the Groves-1 zero-power critical assembly reactor facility.
LOTUS 2.0 (MFC-1765) is the next development phase of the Laboratory for Operation and Testing in the United States. LOTUS 2.0 will be designed and constructed at the current location of MFC-1727.
INL will design, fabricate, and irradiate a second fueled pebble experiment, XPeRT-2 (X-energy Pebble Reactor Test 2), in the Advanced Test Reactor (ATR).
Idaho National Laboratory (INL) is collaborating with Oak Ridge National Laboratory (ORNL), National Laboratory of the Rockies (NLR), and ArcelorMittal, to establish a National Library for both iron ore and steel scraps.
The U.S. Department of Energy (DOE), through the Office of Fossil Energy and Carbon Management (FECM), established the Supply Chain Research Facility (also known as METALLIC) under the Bipartisan Infrastructure Law to support research and development (R&D) activities (Technology Readiness Levels 3–6) that strengthen domestic critical minerals and materials supply chains.
The System Physics Advanced Reactor Criticality (SPARC) Project is a long-term, zero-power critical experiment led by Idaho National Laboratory (INL) in collaboration with Oak Ridge National Laboratory, Los Alamos National Laboratory, and Lawrence Livermore National Laboratory.
This project will enable future wildfire prevention algorithms by adding data to the Grid Event Signature Library that is specifically targeted towards potential wildfire ignition events such as faults, downed conductors, arcing, and conductor slap.
