The accident at the Idaho National Laboratory occurred inside a facility used for remotely handling, processing and examining spent nuclear fuel, radioactive waste and other irradiated materials, the lab said in a series of statements.
The so-called Materials and Fuels Complex is located near the edge of the sprawling 890-square-mile laboratory site in the high desert in eastern Idaho about 38 miles from the city of Idaho Falls.

At least 17 employees were working inside a decommissioned research reactor when "a container was opened for normal, scheduled work, resulting in low-level worker exposure to plutonium," the statement said.

The exposed workers underwent initial decontamination procedures at the complex before they were taken to a medical facility elsewhere on the lab grounds for "further evaluation," the lab said. Details of their condition were not immediately provided.
