The perspective view above illustrates the subterranean storage system for used nuclear fuel and High-Level Waste invented and licensed by Holtec. It is called the HI-STORM UMAX system. The below-ground storage puts the radioactive material in a supremely safe configuration, essentially beyond the reach of extreme environmental phenomena, mendacity of terrorists, or other external events such as aircraft crash.

HI-STORM UMAX is being increasingly adopted by US nuclear plants for on-site storage. Holtec’s proposed consolidated interim storage facility in New Mexico utilizes the HI-STORM UMAX system.
