Department of Energy contractor Savannah River Remediation (SRR) announced on May 11 that it has completed a salt dissolution campaign in Tank 37, one of the underground tanks storing high-level radioactive liquid waste at the Savannah River Site (SRS) in South Carolina.

Savannah River marks 25 years of operations for processing plant

The month of March marked the 25th year of radiological operations for the Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site in South Carolina. Radiological operations at DWPF, which is used to treat Savannah River’s high-level radioactive tank waste, began on March 12, 1996, with the first canister of vitrified waste poured on April 29 that year.

To date, more than 4,200 stainless steel canisters of vitrified waste have been poured at DWPF, according to the DOE.

The only operating waste vitrification plant in the nation, DWPF is operated by Savannah River Remediation, the DOE’s liquid waste contractor at the site. According to the DOE, DWPF operations are expected to continue for approximately 15 more years, and about 4,000 more canisters are scheduled to be produced. The DOE expects to begin hot operations at a second waste vitrification plant later this year at its Idaho National Laboratory site.

Savannah River crews remove cesium columns from tank closure unit

Columns filled with cesium have been removed at the Savannah River Site in a demonstration project designed to accelerate removal of radioactive salt waste from underground tanks.

“On the surface, it appeared to be like any other crane lift and equipment transport, which are routinely performed in the tank farms. However, this equipment contained cesium-rich, high-level waste, which was transported aboveground via roadway to an on-site interim safe storage pad,” said Savannah River Remediation (SRR) president and project manager Phil Breidenbach. “It was all handled safely and executed with outstanding teamwork by our highly skilled workforce.”

Operated by liquid waste contractor SRR, a system known as the Tank Closure Cesium Removal (TCCR) unit removes cesium from the salt waste in Tank 10 in the site's H Tank Farm. The TCCR is a pilot demonstration that helps accelerate tank closure at the site, according to a report by the Department of Energy on February 9.

SRS liquid waste facilities get upgrade to computer operating systems

An upgrade to modernize computer systems across the Savannah River Site's liquid waste facilities while maintaining cybersecurity industry standards was completed recently, the site’s liquid waste contractor announced on June 25. The Savannah River Site is located in Aiken, S.C.
