In operation since 1949, Idaho National Laboratory is a science-based, applied engineering national laboratory dedicated to supporting the U.S. Department of Energy's missions in energy research, nuclear science and national defense. The world's first usable amount of electricity from nuclear energy was generated here in 1951.At 890 square miles (569,135 acres), the INL Site is roughly 85 percent the size of Rhode Island. In addition to our geographic resources, the lab hosts a variety of unique facilities, including the Advanced Test Reactor National Scientific User Facility.Complementing our nuclear research, the lab has numerous alternative energy and national security programs. Robotics, wind power, high-performance computing, biofuels, critical infrastructure protection, carbon management and advanced vehicle testing are just a few examples of our multifaceted research capabilities.
