We operate a low–enriched uranium–fueled, pool–type reactor, the Geological Survey TRIGA® Reactor, to support science by providing information on geologic, plant, and animal specimens to advance methods and techniques unique to nuclear reactors. Samples from around the world are submitted to the USGS for analysis using the reactor facility.
