Geiger Brothers continued to support Fluor-B&W’s mission at the U. S. Department of Energy’s (DOE) former Portsmouth Gaseous Diffusion Plant by building the new X-690 Natural Gas Steam Plant.
The construction done under contract to Fluor/Babcock & Wilcox Portsmouth (FBP) is part of infrastructure and miscellaneous project work in preparation for and as part of Portsmouth Gaseous Diffusion Plant Decontamination & Decommissioning (D&D).
The X-690 Natural Gas Steam Plant will reduce greenhouse emissions and provide ongoing steam to support the D&D project. The new right-sized and efficient steam plant is capable of providing 80,000 to 90,000 pounds of steam per hour. Its two Cleaver-Brooks boilers now are providing heat to more than a dozen buildings more efficiently than its predecessor, the X-600 Coal-Fired Steam Plant, which last operated on October 16 and is now scheduled for demolition. Due to its age (built in 1953), related maintenance, reliability issues and more stringent environmental regulations, the X-600 Steam Plant was not able to continue to efficiently meet site demands.
Geiger Brothers performed design-build for the new $5.8 million X-690 gas-fired plant and self-performed civil, concrete, steel erection, plumbing, process, HVAC, instrumentation/controls and general trades work.
Crews from Geiger Brothers began work in July by pouring concrete foundations and connecting a natural gas line and backup fuel tank. The 20,000 gallon fuel oil tank was set in early August, followed by the two boilers later in the month.
Installation of remaining equipment was completed in early September, followed by testing and startup of the facility. Typically, steam boilers arrive with the burners already attached. In building the X-690 plant, the burners were installed at the scene, which saved nearly three weeks of assembly time.
The Fluor-B&W Facility Custodian said shutting down the X-600 and seamlessly engaging the new X-690 plant was not an easy task. “The steam plant and utilities crews, the project crew and Geiger Brothers have worked long hours and many consecutive days. A lot of people don’t realize how much was done because the steam stayed on and no interruptions occurred.”
