Photos: Inside a nuclear reactor

Technicians in the Idaho National Lab's Advanced Test Reactor work to place an object into the reactor below. Though there is little measurable radiation in the area where they're working, they wear the suits as a precaution. In order to maneuver the object, they use very long-handled tools, which are capable of reaching far down into the reactor.

The Idaho National Lab is, among other things, the U.S. Department of Energy's leading nuclear research institution, and its employees are working on developing the technology behind what would be known as the "fourth-generation" nuclear reactors, facilities that many hope will help provide large amounts of energy with little additional carbon footprint.
