The hot commissioning testing phase of operations at the Salt Waste Processing Facility (SWPF) has been completed, signaling the facility’s entrance into fully integrated operations with the other liquid waste facilities at the Department of Energy’s Savannah River Site in South Carolina.

Radiation shielding, environmental emissions, and product waste acceptance requirements were all tested and validated during the commissioning phase of the SWPF, the DOE announced on January 19. The SWPF will treat the approximately 31 million gallons of remaining salt waste currently stored in underground tanks at SRS.

Parsons Corporation, the contractor that designed and built the first-of-a-kind facility, will operate the SWPF for one year, beginning this month. It is anticipated that the facility will process up to 6 million gallons of waste during the first year of operations.

President Biden has appointed Joyce Connery as chair of the Defense Nuclear Facilities Safety Board (DNFSB). Connery, an ANS member since 2012, was appointed to the board in August 2015 for a term ending in October 2019. She was confirmed again by the Senate as a DNFSB member on July 2, 2020, for a term expiring on October 18, 2024. Connery previously held the chairmanship from August 2015 until January 2017.

The Nuclear Regulatory Commission has extended for two months the public comment period for its draft decommissioning guidance, Consolidated Decommissioning Guidance, Characterization, Survey, and Determination of Radiological Criteria (NUREG-1757, Volume 2, Revision 2).

President Biden designated Christopher T. Hanson as the 18th chairman of the Nuclear Regulatory Commission over the weekend. Hanson replaces Kristine Svincki who resigned from the NRC as chairman on January 20. Svinicki was the longest-serving commissioner in the agency's history (2008-2021).

“I am honored to have been selected by President Biden to serve as the next NRC chairman and to lead the talented women and men who oversee the licensing and regulation of our nation’s civilian use of radioactive materials,” said Hanson. “I look forward to building on Chairman Svinicki’s many accomplishments as the commission takes on new challenges and faces new opportunities as nuclear energy technologies continue to evolve and uses of nuclear materials expand in the future.”

The ST25-HTS tokamak.

Governments around the world have been interested in fusion for more than 70 years. Fusion research was largely secret until 1968, when the Soviets unveiled exciting results from their tokamak (a magnetic confinement fusion device with a particular configuration that produces a toroidal plasma). The Soviets realized that tokamaks were not useful as weapons but could produce plasma in the million-degree temperature range to demonstrate Soviet scientific and technical prowess to the world.

Following this breakthrough, government laboratories around the world continued to pursue various methods of confining hot plasma to understand plasma physics under extreme conditions, getting closer and closer to the conditions necessary for fusion energy production. Tokamaks have been by far the most successful configuration. In the 1990s, the Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory produced 10 MW of fusion power using deuterium-tritium fusion. A few years later, the Joint European Torus (JET) in the United Kingdom increased that to 16 MW, getting close to breakeven using 24 MW of power to heat the plasma.

The Nuclear Threat Initiative (NTI) and the Center for Advanced Defense Studies (C4ADS) last week released Signals in the Noise: Preventing Nuclear Proliferation with Machine Learning & Publicly Available Information, a 22-page report that provides a blueprint for identifying high-risk or illicit nuclear trade. (Machine learning can be defined as a branch of artificial intelligence focused on building applications that learn from data and improve their accuracy over time without being programmed to do so.)

A team of researchers led by Purdue University has used X-ray imaging conducted at Argonne National Laboratory’s Advanced Photon Source to obtain a three-dimensional view of the interior of an irradiated nuclear fuel sample. The use of synchrotron micro-computed tomography could lead to more accurate modeling of fuel behavior and more efficient nuclear fuel designs, according to the researchers.

Britain and Japan have signed a research and technology deployment collaboration to help automate nuclear decommissioning and aspects of fusion energy production. According to the U.K. government, which announced the deal on January 20, the £12 million (about $16.5 million) U.K.–Japanese robotics project, called LongOps, will support the delivery of faster and safer decommissioning at the Fukushima Daiichi reactors in Japan and at Sellafield in the United Kingdom, using long-reach robotic arms.

The four-year collaboration on new robotics and automation techniques will also be applied to fusion energy research in the two countries.

Funded equally by U.K. Research and Innovation, the U.K.’s Nuclear Decommissioning Authority, and Japan’s Tokyo Electric Power Company, the LongOps project will be led by the U.K. Atomic Energy Authority’s (UKAEA) Remote Applications in Challenging Environments (RACE) facility.

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.

Glick

This morning, on his first full day in office, President Joe Biden appointed Richard Glick chairman of the Federal Energy Regulatory Commission. Glick joined FERC as a commissioner in late 2017, having been picked for the job by President Trump in August of that year. His term ends June 30, 2022.

“I'm honored President Joe Biden has selected me to be @FERC Chairman, thank you Mr. @POTUS,” Glick tweeted. “This is an important moment to make significant progress on the transition to a clean energy future. I look forward to working with my colleagues to tackle the many challenges ahead!”

The Nuclear Regulatory Commission has issued an environmental assessment (EA) and finding of no significant impact (FONSI) in connection with its proposed action to extend the completion dates for the Tennessee Valley Authority’s Bellefonte plant reactor construction permits. If approved by the NRC, the construction permits for Bellefonte Units 1 and 2 would extend to October 1, 2021.

In a notice on the EA and FONSI published in the January 19 Federal Register, the NRC explained the reason for the proposed action. “In its March 31, 2017, and August 28, 2020, letters, TVA noted that it sold the Bellefonte property at auction, the sale of Units 1 and 2 did not close, and the purchaser filed a lawsuit against TVA,” the notice said. “TVA stated that an extension is needed to allow the parties additional time to obtain a decision in the lawsuit.”

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.

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.

Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.

Register now to attend the webinar.

In a January 14 "Nuclear Industry Recap of 2020" blog post, attorneys Sachin Desai and Amy C. Roma list some of the actions taken by the federal government over the past 12 months to improve the status of the U.S. nuclear community.

Desai and Roma, both of whom practice nuclear and radioactive materials law at Hogan Lovells, look at actions by the Nuclear Regulatory Commission, the Department of Energy, and Congress and find much to be optimistic about.

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.

Lesher

Shelly Lesher, a University of Wisconsin-La Crosse professor, is hosting the My Nuclear Life podcast series centered on how nuclear science is perceived in the community, La Crosse television station WXOW reported.

My Nuclear Life explores the intersection of nuclear science and society. Lesher, a 2020 American Physical Society Fellow, covers a range of topics, from the use of radium therapy for treating cancer to the U.S. environmental movement.

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.
