"This publication explains the NRC's [U.S. Nuclear Regulatory Commission's] role in the safe packaging and transport of spent nuclear fuel from commercial nuclear power plants. The NRC oversees the design, manufacture, use, and maintenance of containers for these radioactive shipments. However, the NRC does not control the timing or destination of spent fuel shipments."
