Oak Ridge’s K-27 Building Set for Demolition

Workers remove transite panels from the K-27 Building.

The Environmental Management (EM) program in Oak Ridge is more than 96 percent complete with pre-demolition activities at the K-27 Building.

While building demolition gets a lot of attention, it is only a small piece of what it takes to reduce risk and eliminate buildings from the EM portfolio. A video highlights the activities of the K-27 deactivation team and its work.

As the East Tennessee Technology Park deactivation team prepares to hand off K-27 to demolition crews in early 2016, the critical work now focuses on verification walk downs. Similar to a construction project punch list, the verification walk down checklist confirms that all deactivation work has been completed, including the removal of hazardous and radioactive materials and components that exceed onsite waste disposal limits. When walk downs identify conditions outside of the deactivation plan, crews take actions to correct the inconsistencies and achieve compliance.

One of the final steps in the deactivation process will be declaring the building “criticality incredible,” scheduled for early January 2016. Criticality incredible means all materials that could cause a nuclear criticality have been removed.

K-27 is the last of five buildings in Oak Ridge used to enrich uranium for national defense and commercial nuclear fuel. The others, including the mile-long K-25 Building, have already been demolished.
