X-744H Bulk Storage Building

The X-744H Bulk Storage Building was used as a fabricating shop and workshop in 1953 and 1954. The DOE converted the building into a warehouse in 1956. From 1958 through 1964, the DOE used the X-744H Bulk Storage Building for supplemental storage of cylinders containing both pure and depleted material (uranium hexafluoride). Storage cylinders were made of metal, ranging from 2.5 to 14 tons. This building is part of PORTS, which was a part of the U.S. Cold War nuclear weapons complex. PORTS’ primary Cold War era mission was the production of highly enriched uranium by the gaseous diffusion process for defense/military purposes.
