Parsons Completes SWPF Design Capacity Performance Test

CENTREVILLE, Va., Oct. 21, 2019 /PRNewswire/ -- Parsons Corporation (NYSE: PSN) has successfully completed a key test to validate the capacity of Salt Waste Processing Facility (SWPF) at the Savannah River Site, a significant milestone that moves the plant closer to startup.

The Design Capacity Performance Test (DCPT) was completed on September 30, 2019 and successfully demonstrated that the SWPF will perform at a capacity of at least 7.3 million gallons per year. The successful result is the culmination of more than 15 years of project activities validating the integrated design, testing and commissioning of SWPF.

"This is truly a major accomplishment for Parsons and the Department of Energy, demonstrating the performance of the plant, our processes and our people," said Frank Sheppard, senior vice president and SWPF project manager for Parsons. "The facility ran at full capacity during the test period without any major issues and performed exactly as it was designed."

Once operational, SWPF will process the majority of the site's salt waste inventory by treating highly radioactive salt solutions stored in underground tanks at the Savannah River Site. Future processing will occur at 10 times the rate it is being processed today. Removing salt waste, which fills over 90 percent of tank space in the Savannah River Site tank farms, is a major step toward emptying and closing the site's remaining 43 high-level waste tanks.

A key to the success of the project has been the Department of Energy's commitment to designing and operating the processing technology on a smaller scale before delivering the processing capability on a large scale through SWPF.

"The partnership with DOE and the other contractors at Savannah River Site has been tremendous as we've all worked together to bring this technology up to scale," said Tom Burns, senior vice president and SWPF deputy project manager for Parsons.

The DCPT was the most realistic operation on SWPF to date, using simulated radiological chemicals, standard operating procedures, full mock radiological controls for all activities during DCPT, full laboratory sampling and analysis and demonstrated performance of the operations crews.

"The performance of our workforce during this test and throughout this process has been exceptional," said Sheppard. "Their commitment to safety shines through in everything they do. They continue to raise the bar."
