The X-300A houses the electronic monitoring equipment to track plant processing, including the computer-processing unit for the cascade automatic data processing system. 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.

Historical Infomation In support of this report, there are three appendices:Appendix A through C, which consist of survey photographs, historical photographs, and historical drawings, respectively.

Construction History of the X-300A Process Monitoring Building: The X-300A Process Monitoring Building was built in during the initial stage of construction at PORTS (Appendix B, Figures 5 and 6). Also known as the Computer Building, the X-300A Process Monitoring Building houses the electronic monitoring equipment that tracks plant processing, including the computer processing unit for the cascade automatic data processing system. Historical drawings of building plans are included in Appendix C (Figures 7 and 8). Part II. Site Information Description of the X-300A Process Monitoring Building: The X-300A Process Monitoring Building is associated with the Plant Control Facility, and is located just west of the circular domed building.

The X-300A Building is a one-story utilitarian building in a rectangular plan (Appendix A, Figures 2 through 4). The building has a poured concrete slab foundation, reinforced concrete walls, no window openings, and a relatively flat roof. There is an L-shaped concrete block addition on the west half of the southern fa ade. The main building has one entry located on the north fa ade with a heavy solid metal blast door. The addition has two metal entry doors on the west fa ade and one inset in the south fa ade. The main building has square feet of floor space. The interior of the building houses a variety of computers and equipment used in the monitoring of plant processing systems.

Floors in the building are covered with linoleum, with certain panels perforated to allow for increased air flow to keep the computer equipment cool. The walls are clad in a fibrous wallboard material, and the building has a drop ceiling with acoustic tiles and inset troffer-type fluorescent lighting.
