DOE, Congressional Officials Celebrate Launch of Salt Waste Processing Facility at Savannah River Site |
Participants in a ceremonial ribbon-cutting for the Salt Waste Processing Facility (SWPF) at the Savannah River Site on Sept. 24 included, from left, Rep. Joe Wilson of South Carolina; Parsons CEO and President Chuck Harrington; Under Secretary for Science Paul Dabbar; DOE-Savannah River Manager Mike Budney; EM Senior Advisor William "Ike" White; Parsons President and Chief Operating Officer Carey Smith; SWPF Federal Project Director Pam Marks; and Parsons Senior Vice President and SWPF Project Manager Frank Sheppard.
AIKEN, S.C. – The start of operations of the Salt Waste Processing Facility (SWPF) at the Savannah River Site (SRS) represents a leap forward in DOE’s ability to tackle tank waste, one of the most challenging environmental risks, Under Secretary for Science Paul Dabbar said during a Sept. 24 ceremony marking the facility coming online.
“SWPF is the final piece to what is an impressive and highly successful liquid waste program here,” Dabbar, the keynote speaker at the event, said of the facility, which is an EM 2020 priority. “Bringing it online is a tremendous victory, not only for the site, but for the entire cleanup mission.”
Also attending the event were Rep. Joe Wilson of South Carolina, EM Senior Advisor William "Ike" White, and representatives from the offices of Sens. Lindsey Graham and Tim Scott of South Carolina.

Last month, DOE approved Critical Decision 4 (CD-4) for SWPF, clearing the way for “hot” or radioactive operations to begin at the facility. The multi-billion-dollar facility is starting regular operations ahead of schedule and under budget.
SWPF will process the majority of the site’s salt waste inventory by separating highly radioactive constituents for treatment via vitrification, from the predominately low-radioactive, large-volume salts that will be treated for disposal onsite. Removing salt waste, which fills over 90 percent of tank space in the SRS tank farms, is a major step toward emptying and closing the site’s 43 remaining high-level waste tanks.
Completion of the Salt Waste Processing Facility (SWPF) ushers in a new era in the processing of radioactive material, Mike Budney, manager for the Savannah River Operations Office, said during a Sept. 24 ceremony to celebrate the start of SWPF operations.
“This is a big day for us at the site, for the state of South Carolina, for the Department of Energy and, I believe, for the nation, as we recognize completion of SWPF, which will usher in a new era in the processing of radioactive material,” said Mike Budney, manager for the Savannah River Operations Office.
Parsons, which designed and built the first-of-a-kind facility, will operate it for one year. EM and Parsons are completing the remaining commissioning activities necessary to introduce radiological material into the facility.
“We’re celebrating a historic milestone in the transition to fill operations of the Salt Waste Processing Facility,” Parsons CEO and President Chuck Harrington said.
The first transfer of waste to SWPF is currently scheduled for the first week of October.

SWPF to Accelerate Tank Waste Cleanup
AIKEN, S.C. – EM and prime contractor Parsons Corporation are poised to begin transferring radioactive material to the Salt Waste Processing Facility (SWPF) for processing at a rate eight times faster than recent waste treatment operations at the Savannah River Site (SRS).
This major milestone comes 18 years after EM and Parsons embarked on a mission to revolutionize the treatment of radioactive waste contained in the underground liquid waste storage tanks at SRS.
In August, DOE approved Critical Decision 4 and Authorization to Operate for SWPF, authorizing “hot,” or radioactive operations, to begin at SWPF, the final major piece of the liquid waste treatment system to be completed at SRS.
“The startup of SWPF is a testament to the commitment and dedication of the Parsons workforce over the last 12 years of construction and testing,” said Frank Sheppard, senior vice president and SWPF project manager for Parsons. “The SWPF team has achieved this major milestone while focusing on safety and ensuring the long-term operational success of this first-of-a-kind facility.”

With a goal to process 31 million gallons of radioactive salt waste stored in the tanks at SRS, EM selected Parsons to design, build, and commission SWPF, and operate the facility for one year. Parsons finished building SWPF in April 2016, eight months ahead of schedule and more than $65 million under the target cost of the contract for construction activities. Removing salt waste, which fills over 90 percent of tank space in the SRS tank farms, is a major step toward emptying and closing the site’s 43 remaining high-level waste tanks. A precursor to SWPF, the Actinide Removal Process (ARP) and Modular Caustic Side Solvent Extraction Unit (MCU) demonstration advanced radioactive salt waste processing across the EM complex by improving the technology to be used in the larger-scale SWPF. ARP/MCU separated radioactive components from nonradioactive salt solution using a chemical separation process. -Contributor: Bryce McDevitt |
SRS Fully Integrates Liquid Waste System With Salt Waste Processing Facility |
AIKEN, S.C. – EM has successfully integrated the liquid waste treatment system with the Salt Waste Processing Facility (SWPF) at the Savannah River Site (SRS) after 10 years of complex preparatory work.
EM and liquid waste contractor Savannah River Remediation (SRR) made many improvements to prepare SRS liquid waste facilities to handle the output from SWPF and ensure that facility could be fed large quantities of salt waste from the site’s 43 remaining high-level waste tanks.
SRR
President and Project Manager Phil Breidenbach said SRR’s dedication to
the liquid waste cleanup mission is helping make EM history.
“The
work that led to full integration with the Salt Waste Processing
Facility is truly historic,” Breidenbach said. “We demonstrated
technology, modified infrastructure that is over 65 years old, and
modified procedures and programs to ready the liquid waste facilities.
The talented team of SRR professionals all share the same goal — to
eliminate the greatest risk in the state of South Carolina. Together as a
team, we are making the community and environment safer.”
Workers performed research, planning, documentation, and other work to ready 1-million-gallon salt batches for transfer to SWPF. They added transfer lines, excavated a large area to reveal piping for modifications, installed large pumps, and revised documents governing operational procedures.
SWPF integration work was completed without injuries resulting in missed workdays. Safety was the top priority throughout the integration process, as crews trained with mock-ups, deployed remote equipment, and implemented other controls to reduce the risk of radiological and industrial hazards.
SWPF
is key to accelerating the disposition of salt waste, which makes up
approximately 90 percent of the site’s tank waste volume. Workers
previously processed salt waste at the site’s interim salt waste
processing facilities, known as the Actinide Removal Process/Modular
Caustic Side Solvent Extraction Unit. That operation successfully
demonstrated the technology being used in the larger-scale SWPF.
The
first transfer of 4,000 gallons of salt waste through roughly 4,000
linear feet of stainless-steel piping from the site’s Tank 49 to SWPF is
pending. The salt waste will be processed inside SWPF into two streams:
a high-activity radionuclide stream for transfer to the Defense Waste
Processing Facility, and a decontaminated salt solution to be sent to
the Saltstone Production Facility.
Salt batches are prepared in
blend tanks to meet waste acceptance criteria at SWPF, due to each waste
tank containing a unique blend of radioactive liquid waste and
chemicals. Workers recently modified Tank 41 to become a salt waste
blend tank in support of SWPF operations. This work was accomplished by
dissolving salt cake in the tank for transfer and installing a
submersible blend pump. An additional blend tank, Tank 42, is scheduled
to be operational in May 2021.
After crews completed modifications to connect the liquid waste facilities to SWPF, employees with SRR and SWPF contractor Parsons practiced future operations through simulated salt waste transfers between the liquid waste facilities and SWPF. The exercises were an opportunity for the team members to follow new and revised procedures.

EM, NNSA Teams Collaborate on Milestone Waste Shipment to WIPP
The first transuranic waste shipment from Lawrence Livermore National Laboratory in a decade departs the laboratory earlier this month.

The Waste Isolation Pilot Plant mobile loading team processes a recent transuranic waste shipment from Lawrence Livermore National Laboratory. |
As a national security laboratory, LLNL generates TRU waste resulting from research in support of the national defense mission. Since the last TRU waste shipment campaign in 2010, LLNL has been accumulating newly generated waste in its storage facilities, which were projected to reach capacity this year. Without the ability to ship the TRU waste offsite, some research operations could be impacted.
In 2018, LLNL secured funding with NNSA’s Office of Safety, Infrastructure, and Operations to deploy the WIPP Central Characterization Program to characterize and certify LLNL’s inventory of TRU waste. This ensures that all the waste being shipped to WIPP meets disposal requirements for the facility. LLNL updated its safety basis documentation, underwent multiple readiness activities, and began characterizing its TRU waste in 2019.
Once the waste was certified and ready for shipment, the WIPP mobile loading team deployed to LLNL to load the waste containers into TRUPACT-II shipping packages. All WIPP shipments are tracked while en route to the facility using a satellite tracking system known as TRANSCOM, which helps ensure the safety of the shipments. The first shipment of the campaign safely arrived at WIPP on Sept. 19, following the approximate 2,000-mile journey.
The current campaign will continue until the newly certified TRU waste is safely removed from LLNL.

Hanford Site Delivers Safe Progress During Pandemic
RICHLAND, Wash. – When the Hanford Site moved to an essential mission-critical operations posture in late March to ensure the safety of the site and local communities, the number of employees that reported to work dropped to about 10 to 15 percent of the normal 11,000-person workforce. The site had been preparing for a significant reduction in activities and services for several weeks, and thousands of federal and contractor employees had already shifted to a telework status.
Approximately six months later, the site is in the second phase of remobilizing the onsite workforce. More people are working safely onsite than are teleworking, and employees continue to deliver safe progress while protecting the workforce and the local communities during the COVID-19 pandemic.
Shortly after the site began remobilizing in late May, Hanford’s liquid waste processing facilities marked 25 years of safely treating contaminated wastewater while stretching the storage capacity of the site’s underground double-shell tanks. Since 1995, the facilities have processed more than 330 million gallons of contaminated wastewater to remove radioactive and chemical waste, primarily from an industrial evaporator that boils liquid tank waste to evaporate water and increase storage space in the tanks system.
As work ramped up on the site, Hanford’s occupational medical services provider continued to adjust its services to help ensure the health and well-being of Hanford workers. Virtual options were set up for health education, work conditioning, the employee assistance program, and check-ins prior to returning to work. The medical services provider received a 100-percent patient satisfaction response in May, while maintaining an overall patient satisfaction level near that percentage this calendar year.

In June, Hanford officials reported that groundwater treatment systems were on track to meet EM’s goal of treating at least 2.2 billion gallons of contaminated groundwater this fiscal year. Hanford’s advanced pump-and-treat systems allow operations managers to safely monitor the facilities remotely from home, meeting social distancing requirements while ensuring the facilities continued to operate efficiently. Hanford announced earlier this month that the annual treatment goal was surpassed for the sixth year in a row.
That same month, workers finished startup testing at the Analytical Laboratory in Hanford’s Waste Treatment and Immobilization Plant (WTP), marking the first nuclear facility at the plant to reach that point prior to moving into the commissioning phase for operations. That laboratory is a critical part of the system that will be used to treat millions of gallons of waste from Hanford’s underground storage tanks through the Direct-Feed Low-Activity Waste approach. Moving these facilities from the construction to commissioning phase is one of EM’s priorities for 2020.

In July, workers removed obstructions from single-shell tanks as they prepared to retrieve radioactive and chemical waste from the site’s A Tank Farm. At the same time, offsite workers followed COVID-19 safety protocols while they built a full-scale mock-up to test operations to fill three aging underground disposal structures with engineered grout to stabilize the structures later this year.
Workers paved roads and parking lots at WTP, establishing the future operational area of the plant that will treat tank waste. Workers also began installing fencing, utilities, support structures, and other infrastructure for the nearby disposal facility that will receive canisters of vitrified low-activity tank waste. Vitrified waste is immobilized in glass.

In August, training kicked off for the final class of commissioning technicians who will prepare the massive treatment plant for 24/7 operations to vitrify millions of gallons of tank waste. Workers also finished successfully testing a pretreatment system that removes radioactive cesium and solids from tank waste to provide a feed of low-activity waste to the plant, and they started constructing a concrete pad next to Hanford tanks to hold the pretreatment system.
Energy Secretary Dan Brouillette viewed progress on that project and others that month.
“I’m pleased to see the tremendous work the team here at Hanford has done to protect its people, the communities, and the Columbia River,” Brouillette said. “We are now getting ready to move into the tank cleanup phase and address it in a safe, timely and cost-effective manner.”
In August, Energy Secretary Dan Brouillette, at podium, toured AVANTech in Richland to see the Tank-Side Cesium Removal system that will be used at Hanford as part of the Direct-Feed Low-Activity Waste approach to tank waste treatment.
Chemists also made their final move into the Analytical Laboratory, culminating two years of developing training and procedures and verifying laboratory equipment performance while working at a nearby community college.
Workers broke ground on a storage area that will hold dry casks of nearly 2,000 capsules of cesium and strontium that are now stored in an underwater basin, while other workers continued building a mock-up to safely train and test equipment that will be used to move the highly radioactive capsules into the casks.
In the closing weeks of fiscal 2020, Hanford enhanced safety for workers and reduced the risk posed by chemical vapors by installing a new exhauster ventilation system above waste tanks in the A Farm to draw air from the tanks and send filtered air through 50-foot stacks, well above workers. And water treatment plant staff received a distinguished Silver Certificate of Achievement from the Washington State Department of Health for five consecutive years of high performance on removing particles from water to help protect workers at the site.

The award recognized the superb quality of drinking water at Hanford and the team’s high performance for the past five years in removing even the smallest particles from water during treatment to ensure worker safety.
Brian Vance, manager of the EM Richland Operations Office and EM Office of River Protection, encouraged site workers in a recent message.
“Please remember the lessons we have learned over the past few months: maintain social distancing, wear face coverings, wash your hands often, and stay home if you are ill,” said Vance. “I remain confident that, working together, we will move forward towards a prosperous future, continuing to provide safe, efficient and effective cleanup of the Hanford Site.”
