savannah river


This photo, taken with a remote camera, shows an upward view of the #melter pour spout in the Defense Waste Processing Facility (#DWPF) at the Savannah River Site#SRS. This view is known to employees as “the Eye of the Dragon.” With its shape, color, and nearly 2,100-degree Fahrenheit temperature, the nickname suits the view of the pour spout well. A molten glass-waste mixture travels down the pour spout in a pencil-thin stream into stainless steel canisters to cool and harden. The pour spout is a component of DWPF’s 65-ton steel and ceramic melter, where radioactive liquid waste mixed with a sand-like borosilicate glass (called frit) is heated until molten before being poured into the canisters.
The inner circle is the pour spout insert, which is held in place by three pins arranged 120 degrees apart. The pour spout insert is periodically replaced to ensure a clear disengagement edge for the glass stream from the pour spout wall. This replaceable spout is one of the many improvements that helped keep #Melter 2 functional for 14 years. #MelterMonday
