SRR Makes Great Strides During the Past Year
Cleaning up legacy liquid waste from the Cold War is a top priority at the Savannah River Site (SRS). Savannah River Remediation (SRR) is contracted by the U.S. Department of Energy (DOE) to focus on safely dispositioning this waste and operationally closing million-gallon waste tanks.
SRR is making great strides in executing our mission.
The waste – a more radioactive sludge, a less radioactive salt, and contaminated water – is dispositioned through various liquid waste facilities. Removing this waste from the tanks is essential to the Site's mission of cleaning and operationally closing them.
Liquid waste accomplishments for Fiscal Year 2015 included:
- Operationally closing Tank 16 ahead of schedule by filling it with a cement-like grout. It is the seventh underground radioactive high-level waste storage tank closed at the Site, and the fifth tank closed by SRR since 2012.
- Producing 93 canisters of glassified waste at the Site's Defense Waste Processing Facility by turning the sludge into glass. That fiscal year production brings the total number of canisters of immobilized waste to 1,233 since the SRR contract began on July 1, 2009, and a total of 3,970 since DWPF operations began in 1996.
- Processing approximately 752,000 gallons of salt waste at the Actinide Removal Process (ARP)/Modular Caustic Side Solvent Extraction Unit (MCU), bringing the total salt waste prepared to about 5 million gallons under the SRR contract. ARP/MCU removes nearly all radioactive isotopes from the salt waste and separates the salt waste into highly radioactive and decontaminated waste streams for dispositioning.
- Disposing of about 828,000 gallons of Decontaminated Salt Solution and 1.5 million gallons of grout through the Saltstone facilities, bringing the total number of gallons of this waste dispositioned to 8.1 million gallons of Decontaminated Salt Solution and 14.1 million gallons of grout under the SRR contract.
- Finishing the primary construction on Saltstone Disposal Unit 6, the first 30-million gallon mega-volume salt waste disposal unit being built at SRS. The Decontaminated Salt Solution is mixed with grout and placed into these units.
- Creating 2.7 million gallons of tank space through the Site's two evaporators. This is the largest amount of space gain since 2010.
The fiscal year operational accomplishments and tank closures continue to reduce risk and set the stage for the future.
One key reason SRR employees were successful in Fiscal Year 2015 is because they worked the greatest number of hours without a days-away injury in the 6-plus years of the SRR contract, nearly 10 million safe hours.
By doing each job safely, we were able to accomplish more of our mission objectives. I'm proud of their determination to focus on safety while providing the government with solid results based on innovation and cost effectiveness.
In all, our work can be summarized in two words: We deliver.
I encourage you to read through this website for the details of our work and our success. You will see our employees are dedicated to reducing the risk of the legacy liquid waste at SRS.
