UCOR has completed replacement of electrical feeds to 13 well pumps at Solid Waste Storage Areas (SWSA) 4 and 5. These pumps are part of the Melton Valley Hydraulic Isolation wells, which were installed to minimize movement of rain and groundwater through these areas. While the wells have functioned as required by regulatory documents, UCOR…
UCOR’s deactivation and demolition crews officially start deactivation on the 360,000-square-feet Beta-4 facility, a former Manhattan Project-era uranium enrichment building. The National Nuclear Security Administration transferred operational responsibility of the 360,000-square-foot Beta-4 to OREM for the characterization, deactivation, and pre-demolition work. While preparation to begin deactivation on the facility was underway, UCOR’s Y-12 infrastructure crews completed a major…
The Chromium Water Treatment System (CWTS) at the ETTP Heritage Center has successfully completed its five-year dye test. During the test, 45,500 gallons of water tinted with a benign bright green dye were pumped from the 802 Basin to Clinch River mile marker 12.0. The absence of the bright green dye once pumped through 3.3-mile…
ORNL Nuclear Operations has started the final round of above ground piping replacements at the Building 2600 Process Waste Facility. Project, maintenance, and operations crews worked together to minimize the downtime of the Liquid and Gaseous Waste Operations (LGWO) system by replacing piping from the 2105 Sump to the 2106 Sump first. This will allow…
UCOR has made a lot of progress on the Oak Ridge Reservation during the past several weeks, as detailed in the video. Over 325,000 square feet are officially cleared to be reused for future national security missions at the Y-12 National Security Complex. UCOR’s D&D crews are continuing to reduce risk at ORNL’s Isotope Row…
UCOR’s Controlled Low-Strength Material (CLSM) pour team has officially wrapped up filling the Beta-1 basement at Y-12 with over 26,000 cubic yards of CLSM, a cement mix made of fly ash, sand, and cement. The building is in the final stages of being demolition ready. This achievement is a testament to the collaboration and teamwork among…
Heritage Center Closure crews successfully replaced 310 linear feet of stormwater piping at outfall 780. This crucial work allows for the removal of another DOE National Pollutant Discharge Elimination System (NPDES) permit from the East Tennessee Technology Park site. The deteriorated piping and associated sediments will be disposed of at the Oak Ridge Reservation Landfill…

UCOR’s Y-12 deactivation and demolition (D&D) crews have made a critical advancement in the upcoming demolition of the former uranium enrichment facility Beta-1. They have shipped mercury removed from over 820 linear feet of filled drainpipe out of the facility, one of the final steps to reaching condemnation in the upcoming weeks. After being characterized…
UCOR’s Y-12 deactivation and demolition (D&D) crews completed a recent initiative to decrease mercury vapor exposure in Alpha-4. By installing a new ventilation system, they are paving the way for increased operational efficiency and enhanced worker safety in the former uranium enrichment and lithium processing facility. Crews’ personal protective equipment keeps them safeguarded from hazards.…
