Petersen Inc. has been awarded a 2020-2021 Supply Chain Excellence Award by Bechtel for its contributions to the Department of Energy's Hanford Vit Plant (Waste Treatment and Immobilization Plant) project. Companies were evaluated on multiple factors, including overall performance, ability to deliver quality services, and meeting or exceeding expectations of safety, performance, technical expertise, and environmental compliance. For the Vit project, Petersen built two 300-ton melters that will process a portion of the 56 million gallons of radioactive and chemical waste generated during the Manhattan Project and the Cold War. The process involves mixing silica and other glass-forming materials, which are heated to 2,100 degrees Fahrenheit and then poured into stainless steel containers for disposal. Designing and manufacturing the two melters included 1,200 engineering drawings, and fabrication took nearly three years to complete. A third melter is in fabrication as a spare. Petersen is currently manufacturing the stainless steel containers used to dispose of the waste.
