The year in review 2020: Waste Management

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 National Nuclear Security Administration last week released performance evaluation summaries on the effectiveness of its management and operating (M&O) contractors in meeting the agency’s expectations during fiscal year 2020.

The summaries feature assessment “scorecards,” as well as links to M&O contractor performance evaluation and measurement plans. Also included are specific contractor accomplishments, plus issues requiring attention.

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.

Five former chairmen of the U.S. Nuclear Regulatory Commission—Stephen Burns, Allison Macfarlane, Nils Diaz, Richard Meserve, and Dale Klein—signed a letter to José Romero, Arkansas health secretary and chair of the Centers for Disease Control and Prevention (CDC) immunization advisory committee, requesting that the advisory committee update its recommendation for COVID-19 vaccine allocation guidance for the energy workforce (including nuclear energy workers).

Currently, the CDC has four phases for the COVID-19 vaccine rollout. Those phases are numbered:

• 1a (the current phase), reserved for healthcare workers and those living in long-term care facilities;
• 1b, reserved for people 75 years and older and frontline essential workers;
• 1c, reserved for persons 65 to 74 years old, those aged 16 to 64 who have high-risk medical conditions, and other categories of essential workers (this includes energy workers); and
• 2, for everyone else that was not named in the previous three phases aged 16 to 64.

Among the executive orders President Trump issued during his last weeks in office was “Promoting Small Modular Reactors for National Defense and Space Exploration,” which builds on the Space Policy Directives published during his term. The order, issued on January 12, calls for actions within the next six months by NASA and the Department of Defense (DOD), together with the Department of Energy and other federal entities. Whether the Biden administration will retain some, all, or none of the specific goals of the Trump administration’s space nuclear policy remains to be seen, but one thing is very clear: If deep space exploration remains a priority, nuclear-powered and -propelled spacecraft will be needed.

The prospects for near-term deployment of nuclear propulsion and power systems in space improved during Trump’s presidency. However, Trump left office days after a hot fire test of NASA’s Space Launch System (SLS) rocket did not go as planned. The SLS rocket is meant to propel crewed missions to the moon in 2024 and to enable a series of long-duration lunar missions that could be powered by small lunar reactor installations. The test on January 16 of four engines that were supposed to fire for over eight minutes was automatically aborted after one minute, casting some doubt that a planned November 2021 Artemis I mission can go ahead on schedule.

A four-year campaign to repatriate 161 kilograms of highly enriched uranium liquid target residue material (TRM) from Chalk River Laboratories in Ontario, Canada, to the Savannah River Site in Aiken, S.C., has been completed, the National Nuclear Security Administration (NNSA) and Atomic Energy of Canada Limited (AECL) announced on January 12.

The campaign was conducted under the U.S.-Origin Foreign Research Reactor Spent Nuclear Fuel Acceptance Program, established in 1996 to return U.S.-origin spent nuclear fuel and other weapons-grade nuclear material from civilian sites worldwide. Other partners involved in the effort included the Department of Energy’s Office of Environmental Management (EM), Canadian Nuclear Laboratories, Savannah River Nuclear Solutions (SRNS), and Savannah River National Laboratory as well as state and tribal governments.

The TRM is the by-product of the production of medical isotopes from AECL’s now-shuttered National Research Universal reactor. The repatriation of the material, begun in 2017 and completed in 2020, involved 115 separate truck shipments, covering some 150,000 miles, according to the announcements.

Slaybaugh

The Department of Energy’s Lawrence Berkeley National Laboratory recently named Rachel Slaybaugh, ANS member since 2003 and associate professor of nuclear engineering at the University of California–Berkeley, to lead the lab’s Cyclotron Road Division.

Get to know her: Prior to coming to Berkeley, Slaybaugh served as a program director for the DOE’s Advanced Research Projects Agency-Energy (ARPA-E), whose mission is to advance high-potential and high-impact energy technologies. From 2017 through 2020 at ARPA-E, Slaybaugh led programs supporting research in advanced nuclear fission reactors, agriculture technologies, and sensing and data analytics for four years.

The Department of Energy’s National Nuclear Security Administration will hold two virtual public meetings on a new environmental impact statement for its Surplus Plutonium Disposition Program (SPDP). The meetings will be held on Monday, January 25, from 5 p.m. to 9 p.m. (ET) and Tuesday, January 26, from 7 p.m. to 11 p.m. (ET). Participants can join by computer, telephone, or other device. A Notice of Intent contains a full description of the proposal and other options for providing public comment until February 1.

The program: The SPDP EIS will analyze alternatives for the disposition of 34 metric tons of surplus plutonium using the capabilities at multiple sites across the United States. The NNSA’s preferred alternative, the dilute and dispose approach (also known as plutonium downblending), includes converting pit and non-pit plutonium to oxide, blending the oxidized plutonium with an adulterant, and emplacing the resulting transuranic waste underground in the Waste Isolation Pilot Plant (WIPP), in New Mexico. The approach would require new, modified, or existing capabilities at the Savannah River Site in South Carolina, Los Alamos National Laboratory in New Mexico, the Pantex Plant in Texas, and WIPP.

Despite all the challenges of the COVID-19 pandemic, the U.S. nuclear energy community pulled out some big wins in 2020, and this year could be even bigger, according to the Department of Energy’s Office of Nuclear Energy.

From deep space exploration on Mars to a historic new reactor coming online in Waynesboro, Ga., 2021 will be a record-breaking year for the industry—both good and potentially bad.

Bookless

The acting head of the National Nuclear Security Administration will resign January 20, Inauguration Day, according to a report in the Aiken (S.C.) Standard. William Bookless, who has more than four decades of experience in the nuclear security field, will also retire from federal service that day, the agency confirmed to the Standard.

The NNSA has made no official announcement or named a replacement for Bookless as of Thursday morning.
