ANS International High-Level Radioactive Waste Management Topical Meeting

The Department of Energy is considering disposing of contaminated process equipment from its Savannah River Site (SRS) at a commercial low-level waste facility using its recent interpretation of the statutory term “high-level radioactive waste,” which classifies waste generated from the reprocessing of spent nuclear fuel based on its radiological content rather than its origin.

The Department of Energy’s Office of Nuclear Energy (DOE-NE) last week released its Strategic Vision report, outlining its plan to support the current U.S. reactor fleet, demonstrate the latest innovations in nuclear energy technologies, and explore new market opportunities for nuclear energy.

The 36-page document identifies five goals to address challenges in the nuclear energy sector, help realize the potential of advanced technology, and leverage the unique role of the federal government in sparking innovation. Each goal also includes supporting objectives to ensure progress.

A Department of Energy report to the U.S. Congress shows that the reclassification of high-level radioactive waste could save more than $200 billion in treatment and disposal costs while allowing DOE sites to be cleaned up sooner—all still without jeopardizing public health and safety.

The report, Evaluation of Potential Opportunities to Classify Certain Defense Nuclear Waste from Reprocessing as Other than High-Level Radioactive Waste, identifies potential opportunities for the DOE to reduce risk to public and environment while completing its cleanup mission more efficiently and effectively. Those opportunities are based on the DOE’s 2019 interpretation of the statutory term HLW, which classifies waste based on its radiological characteristics rather than its origin.

Under the DOE’s interpretation of HLW, waste from the reprocessing of spent nuclear fuel may be determined to be non-HLW if the waste (1) does not exceed concentration limits for Class C low-level radioactive waste as set out in federal regulations and meets the performance objectives of a disposal facility; or (2) does not require disposal in a deep geologic repository and meets the performance objectives of a disposal facility as demonstrated through a performance assessment conducted in accordance with applicable requirements.

The U.S. Department of Commerce and Rosatom, Russia’s state atomic energy corporation, have signed a final amendment to the Agreement Suspending the Antidumping Investigation on Uranium from the Russian Federation. The amendment extends the 1992 pact through 2040 and reduces U.S. reliance on uranium from Russia during that time period, the DOC announced October 6.

Previously, the agreement was set to expire on December 31 of this year. According to the DOC, the document’s expiration “would have resulted in unchecked imports of Russian uranium, potentially decimating the front-end of the nuclear fuel cycle in the United States.”

The final amendment is unchanged from the draft version, released for public comment on September 11. (For more specifics on the amendment, see our story on the draft here.)

The Nuclear Regulatory Commission has scheduled four webinars in October to present its draft environmental findings and receive comments on Interim Storage Partners’ (ISP) proposed consolidated interim storage facility for used nuclear fuel in Andrews County, Texas.

Information for the webinars will be posted on the NRC’s Public Meetings webpage. The webinars will be held at different times of the day to maximize opportunities for the public to participate and are tentatively scheduled for the following (all times are Eastern):

• October 1, 6 p.m. – 9 p.m.
• October 6, 2 p.m. – 5 p.m.
• October 8, 6 p.m. – 9 p.m.
• October 15, 11 a.m. – 2 p.m.

The Department of Energy approved the start of operations at the Salt Waste Processing Facility (SWPF) at the Savannah River Site (SRS), authorizing hot (radioactive) operations to begin at the facility, the agency announced on August 17.

The approval comes five months ahead of the current baseline completion date of January 31, 2021. Parsons Corporation, which designed and built the first-of-a-kind facility, will operate it for one year.

“This is a considerable achievement for EM's (Environmental Management) cleanup program and will drive significant progress in treating the tank waste at SRS in the next decade,” said William “Ike” White, senior advisor for the EM to the Under Secretary for Science.

The Department of Energy’s demonstration case of how it applies its interpretation of high-level radioactive waste is set to go forward, as the department issued an environmental assessment (EA) report, Final Environmental Assessment for the Commercial Disposal of Defense Waste Processing Facility Recycle Wastewater from the Savannah River Site (final EA), and a finding of no significant impact (FONSI) for the disposal of the waste at an off-site facility.

Based on the final EA, the DOE intends to ship up to 8 gallons of recycle wastewater from the Savannah River Site’s Defense Waste Processing Facility (DWPF) to the Waste Control Specialists disposal facility in Andrews County, Texas, starting within the next 12 months. Under the final EA, up to 10,000 gallons DWPF recycle wastewater may be disposed of at a licensed facility outside of South Carolina.

The 2020 Waste Management Conference, held March 8–12 in Phoenix, Ariz., kicked off just days before the World Health Organization declared the spread of the novel coronavirus a pandemic. When the conference began, it was still unclear how extensive the coronavirus outbreak would be, and meeting organizers later learned that two attendees were tested for COVID-19, the disease caused by the virus, in the days following the meeting. Fortunately, neither of the attendees tested positive.

Deep in the underground of a New Mexico desert, the Department of Energy is studying the effects of high-level, heat-generating radioactive waste on water migration in the salt formations. At the Waste Isolation Pilot Plant (WIPP) near Carlsbad, N.M., a collaboration between Sandia, Los Alamos, and Lawrence Berkeley National Laboratories is performing a series of borehole-scale process tests, called the Brine Availability Test in Salt (BATS) project.
