Uranium Processing Facility
Five walls were poured and completed at the Main Processing Building (MPB) during the month of June. Rack and grid modules in the South side of MPB were completed, with installation beginning on the North side during the month of July. MPB also received and installed its first over-the-top process module for future nuclear mission work.
Crews began installing structural steel for the East columns, beams, and primary floor modules.
Both piping and electrical crews continue to install hangers and large bore piping on the first floor of MPB. The floors are being grit blasted in preparation for floor coatings, and installation of metal studs for dry walls began in this area.
Crews at the Salvage & Accountability Building (SAB) successfully completed the last concrete placement for the elevated decks in June. Work continues as structural and roof steel is installed on the first elevation. Ironworkers will continue to plumb-up, rack, tension, survey, and place metal decking on the roof, making it safe for employees to complete the structure. Mechanical crews have received and installed three of the final twelve over–the-top modules. Due to their size, the over-the-top modules were installed vertically through floor penetrations prior to the roof steel.
Work progresses at the Mechanical Electrical Building (MEB) as electrical cable pulling and terminations continue to support the following Category 1 systems: grounding, lightning protection, emergency lighting, building lighting, medium voltage power, low voltage power, and direct current power. The systems will be working through final construction activities to support turnover to start-up in July and August.
With the completion of all piles in the Process Support Facilities (PSF), Process Gas Yard (PGA) and PSF truck bay during June, final excavation and mud mat placements will take place throughout July. Additionally, teams will start placing rebar in preparation for PSF's foundation.
