OAK RIDGE, Tenn.Oak Ridge’s EM program and its cleanup contractor URS|CH2M Oak Ridge (UCOR) recently completed demolition of the K-633 Test Loop Facility. This project eliminates one of the most contaminated remaining buildings at the East Tennessee Technology Park (ETTP).

   Crew began taking down the structure in early May, and they finished removing debris June 14.  

   Building K-633 is the fourth building Oak Ridge’s EM program has removed from ETTP’s Poplar Creek area since last year. Prior to those teardowns, this area contained 11 large buildings and numerous structures built in the 1940s and 1950s to support the site’s former nuclear program and operations. The Poplar Creek area contains the most contaminated facilities left at the site, following the demolition of five massive gaseous diffusion uranium enrichment buildings.

   “Significant cleanup efforts are underway in ETTP’s Poplar Creek area,” said Acting ETTP Portfolio Federal Project Director Karen Deacon. “We began demolition last year, and the area already looks drastically different. The latest completion moves us closer to achieving our goal to finish the Poplar Creek area demolitions by the end of next year.”

   The building consisted of four separate and independent testing loops. The first three loops were built to test and evaluate gaseous diffusion equipment performance under production conditions. The final loop was installed in 1981 to evaluate prototype equipment designed for gas centrifuge enrichment. DOE ultimately shut down the 18,100-square-foot facility in 1984. 

All of the debris has already been removed from the demolition project.

   The radiological contaminants in the building were affixed inside piping and equipment using fixatives and foam, allowing for safe demolition of the structure.

   The goal for EM and UCOR is to transform the old government-owned uranium enrichment complex into a thriving privately owned industrial park. To date, EM has torn down more than 400 facilities and transferred more than 1,000 acres. 

   The next facility slated for demolition at ETTP is the Toxic Substances Control Act Incinerator. That work begins this month.
