2000 Multi-Application Small Light Water Reactor The seed of NuScale’s eventual small modular reactor was this 45-megawatt unit capable of generating electricity but also adaptable for process heat applications such as water desalination or district heating. 2000 Universal Solvent Extraction Idaho researchers helped develop the UNEX process for simultaneous separation of cesium, strontium and actinides in acidic high-activity tank waste. 2004 Space and Security Power Systems Idaho became the place where radioisotope thermoelectric generators for NASA deep space missions are assembled and tested. 2005 Lead Nuclear Energy Laboratory Idaho and Argonne-West research activities were combined to create today’s INL, which was named DOE’s lead lab for nuclear energy R&D. 2006 TRISO FuelTesting Idaho resurrected research into tri- isotropic fuel, a specialized fuel intended for high- temperature gas reactors. 2008 Multiphysics Object Oriented Simulation Environment INL researchers began developing MOOSE on a foundation of existing computer code and numerical libraries. 2011 AccidentTolerant Fuel After the tsunami-caused Fukushima disaster, INL accelerated work on fuels that could withstand extreme conditions for longer periods of time without failing. 2015 Irradiated Materials Characterization Laboratory The IMCL incorporated many features designed to allow researchers to safely conduct microstructural-level investigations on irradiated fuel. 2017 Resumption ofTransientTesting After more than two decades in standby mode, theTransient ReactorTest Facility (TREAT) was restarted on Nov. 15, 2017, and completed its first transient two months later. 2018 VersatileTest Reactor INL was named to lead DOE’s newVersatile Test Reactor program, an effort to develop a fast-spectrum irradiation test reactor in the United States by 2026. 2014 Commercial Small Modular Reactor The Carbon Free Power Project called for building an SMR power plant on the INL Site using NuScale Power’s technology.
