The Department of Energy’s Environmental Management (EM) cleanup and closure mission involves unique management, regulatory, technical and administrative challenges, which differ from typical operating situations or other environmental cleanups. As the country’s first large nuclear cleanup and closure site, Rocky Flats Environmental Technology Site (RFETS) managers were faced with first-of-a-kind issues that required bold and innovative approaches to undertake and accelerate the closure effort. This was the case nearly two years ago when the project was challenged with the task of dismantling hundreds of gloveboxes from former nuclear production buildings.
