From U.S. Department of Energy “EM Update” email newsletter

U.S. Department of Energy Office of Environmental Management crews at Oak Ridge are moving closer toward completing the first-ever demolition of a former uranium enrichment facility at the Y-12 National Security Complex as crews reroute utilities around the structure.

Workers are slated to begin demolition on the Alpha-2 building this fall. Initiating teardown of the facility is an EM priority for 2024.

The 325,000-square-foot Manhattan Project-era facility is one of nine uranium enrichment process buildings constructed at Y-12. Its removal by the Oak Ridge Office of Environmental Management (OREM) and contractor UCOR will eliminate a high-risk excess contaminated facility, enable modernization, and clear land to support national security missions.

Note: This story was last updated at 4 p.m.

The earthquake near Decatur early Wednesday morning was felt in Oak Ridge, according to social media reports. Oak Ridge Today readers reported feeling the earthquake in other communities such as Clinton, Hardin Valley, Harriman, Oliver Springs, Sevier County, and Atlanta.

The 4.4 magnitude earthquake was also felt in other areas across the Southeast, including in Tennessee, Georgia, and North Carolina.

Some people in the region described it as like a train or truck driving by, and they said homes shook, and doors and windows rattled. Some said it woke them up, and others said they didn’t feel it. (Oak Ridge Today did not feel it.)

The earthquake was reported about nine kilometers underground at 4:14 a.m., according to the U.S. Geological Survey. The epicenter was 11 kilometers north-northeast of Decatur. Oak Ridge is about 45 miles northeast of Decatur.

It was reported to be the largest in Tennessee since a 4.7 magnitude earthquake in Maryville in 1973 and the second strongest on record in East Tennessee. The Maryville earthquake 45 years ago was the strongest in East Tennessee. [Read more…]

The Tennessee Valley Authority is asking for public comment on a proposed Environmental Investigation Plan for coal combustion residuals at Bull Run Fossil Plant in Claxton, across the Clinch River from east Oak Ridge.

TVA is developing the plan and seeking public comment following direction from the Tennessee Department of Environment and Conservation regarding coal ash and other coal combustion residuals stored at TVA’s coal plants in Tennessee, a press release said.

The Bull Run Fossil Plant Environmental Investigation Plan provides details on how TVA plans to investigate and assess the risks to soil, surface water, and groundwater from coal combustion residuals stored at Bull Run, the press release said.

This is not related to the review of generating assets announced at TVA’s August board meeting, the press release said. [Read more…]
