Fluor B&W Portsmouth LLC photographed the site on August 5, Gray & Pape, Inc., Cincinnati, Ohio, served as the primary author of the historical narrative and resource descriptions drawing from numerous historical records and reports, drawings, photographs and plans. For additional contextual information, see Portsmouth Gaseous Diffusion Plant, HAER no. OH-142. This Security Portal HAER was completed in PORTSMOUTH GASEOUS DIFFUSION PLANT, SECURITY PORTAL HAER No. OH-142-K (Page 2) Part I. Historical Information In support of this report, there are three appendices that are provided: Appendix A through C, which consist of survey photographs, historical photographs, and historical drawings, respectively.

Construction History of the Security Portal: Possibly due to its minimal design, few details exist regarding the construction history of the Security Portal. Available plans indicate that A.M. Kinney, Inc., of Cincinnati, Ohio, served as consulting engineers for the building. Primary contractor, Peter Kiewit Sons Construction Company approved the plans for the Security Portal in May Peter Kiewit Sons Construction Company s own forces handled all construction activities for the portal (Appendix B, Figure 4). They initiated excavation on July 20, One week later, the contractor began pouring the concrete foundation. They completed all concrete work by October 11, By March 7, the portal was ready for use. Historical drawings of building plans are included in Appendix C (Figures Part II.

Site Information Description of the Security Portal: The Security Portal (also known as North Portal) is located just south of the southeast corner of the Maintenance and Stores Building. It is one of three portals that facilitate pedestrian access to controlled areas of PORTS. The Security Portal provides access to the north end of the site. In addition to pedestrian access, the Security Portal also features guard booths, benches for workers awaiting buses, and bicycle storage. Measuring approximately 37' by (approximately square feet), the Security Portal consists of a nominally, flat roof supported by a series of steel pipe posts, steel beams, and cinderblock walls (Appendix A, Figures The roof pitches slightly toward the center of the building.

This building is largely wide open with the flat roof functioning as a wide overhang. A cinderblock wall divides the center of the south end of the shelter. Benches line each side of the cinderblock divider. A series of bicycle racks are located on the west side of the south end of the building. The north half of the Security Portal features three guard booths. The booths served as badge exchange stations for workers. Workers were required to wear calibrated thermoluminescent dosimeter badges with identification when at PORTS. These badges were used for security purposes and to monitor worker exposure to radiation. As workers exited PORTS at the end of their shift, they dropped their security badges through slots located in the sides of the security guard booths.

A guard reissued the badges upon return to work. Also built of cinderblock, each booth includes a pair of steel sash, double-hung windows. The windows are an unusual, 2/2 design, with the panes of each window located one above the other. Access to the guard booths is facilitated by a single doorway for each, individual booth. A chain link fence, topped by barbed wire, separates the main parking lot from the facility. Workers entering controlled areas of PORTS were required to pass through one of three rotary gate and turnstiles. These entrance portals are located between the guard shelters in the north end of the Security Portal. PORTSMOUTH GASEOUS DIFFUSION PLANT, SECURITY PORTAL HAER No. OH-142-K (Page 3) Part III.
