2.0 Site Status Summary

The CB&I Technology Development Laboratory (TDL) was an analytical and engineering laboratory serving a wide variety of government and commercial clients. The laboratory consists of a 16,395 square foot main building housing 9 laboratory rooms and support areas. Ancillary buildings include a shop, a materials storage trailer, a block house used for reagent storage, a sample storage shed, and a waste storage building with separate sections used for hazardous and radioactive waste storage.

The TDL was originally licensed in 1975 (License Number R-4755-L5) by the Tennessee Division of Occupational and Radiological Health for electron capture detectors (ECDs) in gas chromatographs. The license number was changed to R-47055-L90 with Amendment 11, issued in 1986. The license authorized various makes and models of ECDs through Amendment 18.

Over the life of the facility, ownership of the lab has changed from Hydroscience Associates, Inc., to IT Environscience, to IT Corporation, to Shaw Environmental, Inc., to CBI. The license was amended in its entirety with Amendment 38, issued in April 2010. Amendment 40, issued in March of 2014, changed the authorized use to storage, security, and analytical procedures as needed in preparation for decommissioning. The license authorizes radioactive materials with atomic numbers between 3 and 98 inclusive in any form. Additional authorized radionuclides include tritium, uranium-233, uranium-235, plutonium, natural and depleted uranium, and natural thorium.
