Building Demolition Activities June – July 2016

Building Demolition Continues April – June

Winter Shutdown December 2015-March 2016

In December 2015, 8 containers holding 272,560 pounds of debris and higher activity wastes were shipped to Energy Solutions in Utah. The remaining liquid wastes on-site were also shipped out to Energy Solutions in December, totaling 27,880 pounds of corrosives (acids / bases), lab chemicals, and oils/oily wastes. These two shipments completed the removal of materials from the building interior.

Over the winter, site activities have focused on the final cleaning of the interior of structures. This process included HEPA vacuuming of interior surfaces and applying a spray coating to cause any residual dust to adhere to the surfaces. Buildings A, B, C, E, and B4 have been completed and are ready for demolition. Building D is nearly complete with the exception of the north end, which has been left for storage and loading of debris generated during the cleaning process.
