The former Steam Plant provided steam to heat buildings, vaporize uranium, maintain process temperatures, and clean equipment. The former Steam Plant produced 125-pounds per square inch (psi) saturated steam and consisted of three boilers, each rated for continuous operation at pounds of steam per hour at 125 psi. The boilers were fired with coal fed through stokers. This facility was 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.

This Steam Plant HAER was completed in PORTSMOUTH GASEOUS DIFFUSION PLANT, STEAM PLANT HAER No. OH-142-Q (Page 2) Part I. Historical Information 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 Steam Plant: Peter Kiewit Sons Company and the AEC awarded the subcontract for the Steam Plant to the James Leck Company of Minneapolis, Minnesota, with Peter Kiewit Sons Company expediting and coordinating the work. Excavation proceeded from January to October with a total of cubic yards excavated (Appendix B, Figures 4 and 5). Eight hundred and thirty-four cubic yards of concrete were laid between July and January (Figures 6 through 9). Towne Construction Company erected 214 tons of structural steel, using both bolted and riveted connections, between August and November (Figures 10 through All work was completed on the initial phase of the Steam Plant by early October (Figures 13 through A view of the Steam Plant in is shown in Figure 20.
The Steam Plant was demolished in Historical drawings of building plans are provided in Appendix C (Figures 21 through Part II. Site Information Description of the Steam Plant: The former Steam Plant was a large facility located in the south-central portion of PORTS, approximately southeast of the Process Building. The Steam Plant provided the steam for the gaseous diffusion process and building heating, uranium vaporization, and equipment cleaning. The building had a floor space of approximately square feet. The building had a rectangular plan with two connected areas, a 72' high east wing, and a 37' high west wing (Appendix A, Figures 1 through 3). Both wings were approximately 99 ' long with two main floor levels and operating platforms.
A control room addition was built on the west facade sometime after the plant s initial construction. The building featured a reinforced, poured concrete, raised foundation that covered the first floor of the plant. The upper story of the building was composed of a reinforced steel frame with corrugated cement- asbestos siding. Each wing of the building had a flat steel-decked roof covered with built-up material and slag. A row of air-intake louvers lined the top of the west wall of the east wing, with additional venting in the first story concrete wall. The west wall of the west wing featured steel industrial windows running the length of the facade. The eastern portion of the plant was occupied by three large coal-fired boilers and stacks.
To the east of the stacks were three steel hopper-like chambers, built ca. Additionally, two silos were located on the southwest corner to store ash. One silo dated to the plant s original construction and was made of tile block, and the other silo was added later and was built of concrete. A coal conveyor was attached to the south fa ade of the taller west wing of the plant to transport coal from the yard to the southeast. The interior of the building consisted of a concrete slab floor resting on compacted fill on the first story and another concrete slab floor on the second story, which was supported by the steel frame and concrete perimeter walls. Mezzanines, platforms, and stairs were steel.
The building housed boilers and their auxiliary units, coal-feed equipment, condensate storage tanks and piping, electrical equipment and controls, and other mechanical equipment. Personnel facilities in the building included lockers, restrooms, and showers. PORTSMOUTH GASEOUS DIFFUSION PLANT, STEAM PLANT HAER No. OH-142-Q (Page 3) Part III.
