Introducing HI-STORM CIS for Consolidated Interim Storage of Used Nuclear Fuel

We are pleased to announce the completion of the development of an underground used fuel storage technology, termed HI-STORM CIS, to store large quantities of used nuclear fuel at a Consolidated Interim Storage (CIS) facility envisioned by the Blue Ribbon Commission. Begun in the wake of 9/11, Holtec’s underground storage technology has steadily matured over the past 10 years. The HI-STORM CIS facility (see schematic below) is the next generation underground storage design that will house used fuel packaged in any canister supplied by any cask vendor. The HI-STORM CIS features a monitored underground storage cavity with the used fuel’s decay heat passively rejected to the ambient air above and its radiation contained within the earth’s subterranean continuum. The radiation released to the environment from the HI-STORM CIS facility storing vast quantities of used fuel equates to a fraction of the background cosmic and solar radiation that pervades our planet, i.e., negligibly small.
