Roman glass, submerged in the ocean for 2,000 years, is providing researchers with confirmation of the effectiveness of glass as a radioactive waste storage medium. This close-up of the glass reveals iridescent corrosion layers caused by the undersea environment. Scientists, funded jointly by the U.S. Department of Energy offices of Nuclear Energy and Environmental Management, are examining glass retrieved from a first-century Adriatic Sea shipwreck to better understand corrosion impacts. The new knowledge helps refine and validate models that predict how glass encapsulation of radioactive waste for long-term storage will hold up over thousands of years. The research has been conducted in Pacific Northwest National Laboratory’s Radiochemical Processing Laboratory and at EMSL, the Environmental Molecular Sciences Laboratory, a DOE Office of Science national scientific user facility located at PNNL.
