The use of uranium is an alternative energy source to petroleum products and some of the United States’ highest quality ore is located on the Colorado Plateau. However, some regions where suitable mining efforts are conducted include areas that are near important environmental resources such as National Parks that provide viewscapes and habitat for wildlife.
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.
The U.S. National Ice Core Laboratory is a facility for storing, curating, and studying ice cores recovered from the polar regions of the world. It provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a repository for current and future investigations.
The laboratory capabilities include imaging, x-ray analysis, x-ray mapping, image processing, and optical microscopy.
SHRIMP-RG stands for Sensitive High-Resolution Ion Microprobe with Reverse Geometry.
