When a SpaceX rocket lifted off from Kennedy Space Center on September 10 (see video here), sending a crewed commercial mission into low Earth orbit, an experiment designed by Pacific Northwest National Laboratory was onboard. Several high-purity metal samples will orbit Earth and absorb cosmic radiation for five days—including that from the Van Allen radiation belt—to help the lab answer questions about the radiation environment for manned space missions, according to a news release from PNNL.

Researchers have been working frantically to develop an array of materials and fibers to economically extract uranium from seawater—and they have succeeded. PNNL scientists exposed this special uranium-sorbing fiber developed at ORNL to Pseudomonas fluorescens and used the Advanced Photon Source at Argonne National Laboratory to create a 3-D X-ray microtomograph to determine microstructure and the effects of interactions with organisms and seawater.

America, Japan, and China are racing to be the first nation to make nuclear energy completely renewable. The hurdle is making it economical to extract uranium from seawater, because the amount of uranium in seawater is truly inexhaustible.

While America had been in the lead with technological breakthroughs from the Department of Energy’s Pacific Northwest and Oak Ridge National Laboratories, researchers at Northeast Normal University in China have sprung ahead. But these breakthroughs from both countries have brought the removal of uranium from seawater within economic reach. The only question is when will the source of uranium for our nuclear power plants change from mined ore to sea­water extraction?

Seven companies get GAIN vouchers in this year’s third award round

June 27, 2023, 12:00PMNuclear News

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced June 26 the companies that have received GAIN Nuclear Energy Vouchers, which allow private companies to access the expertise and research capabilities of Department of Energy national laboratories to advance their projects toward commercial deployment. This is the third round of GAIN vouchers awarded for fiscal year 2023; the first round was announced in December 2022 and the second in March.

Research quantifies the health and climate value of the U.S. nuclear fleet

Nuclear power is the single largest source of clean energy in the United States, but how can the value of “clean” be measured? Two recent reports by researchers at the Massachusetts Institute of Technology and Pacific Northwest National Laboratory, respectively, measured the clean energy benefits of nuclear energy in different ways: the benefits to human health from the air pollution avoided and the future economic value of avoided carbon emissions.

Carbon value: Lifetime extensions of nuclear reactors could save billions in climate mitigation costs

June 24, 2022, 2:49PMNuclear NewsBeth Burmahl

On the road to achieving net-zero by midcentury, low- or no-carbon energy sources that slash carbon dioxide emissions are critical weapons. Nevertheless, the role of nuclear energy—the single largest source of carbon-free electricity—remains uncertain.

Nuclear energy, which provides 20 percent of the electricity in the United States, has been a constant, reliable, carbon-free source for nearly 50 years. But our fleet of nuclear reactors is aging, with more than half of the 92 operating reactors across 29 states at or over 40 years old—the length of the original operating licenses issued to the power plants. While some reactors have been retired prematurely, there are two options for those that remain: retire them or renew their license.

INL reactor deployments could be replicated under Net Zero Labs initiative

May 31, 2022, 7:14AMNuclear News

Four national laboratories have been chosen by the Department of Energy to receive a combined $38 million to launch the Net Zero Labs Pilot Initiative: Idaho National Laboratory, National Energy Technology Laboratory, National Renewable Energy Laboratory, and Pacific Northwest National Laboratory. The pilot program is planned as “a foundation of net-zero solutions that can be replicated at facilities across DOE, the federal government, and state and local governments” in support of the administration’s goal of reaching net-zero greenhouse gas emissions no later than 2050, according to the DOE. Additional funding is expected to be available to all 17 national laboratories on a competitive basis next year.

Two student interns at Pacific Northwest National Laboratory looking for an easier way to monitor the acidity and phosphate concentrations of a process fluid like dissolved nuclear fuel have published research on a monitoring method that provides real-time data without the need for physical sampling of the substance. Their story was published on October 27 on PNNL’s website.

Student leaders: Hope Lackey conducted pH measurement and chemical analysis research during her Science Undergraduate Laboratory Internships (SULI) experience at PNNL in 2018 while she was working toward her undergraduate degree in environmental studies at the College of Idaho. Andrew Clifford, also a SULI intern and a student at the College of Idaho, partnered with Lackey between his junior and senior year, while studying for a dual bachelor’s in chemistry and math/physics.

In a program sponsored by the National Nuclear Security Administration’s Office of Defense Nuclear Nonproliferation, teams of engineering students from Washington State University designed, built, and delivered prototype equipment to address challenges encountered by Pacific Northwest National Laboratory staff in research on nuclear safeguards.

As reported on March 11 by the NNSA, two teams of WSU students presented their projects to PNNL staff during an online meeting in December 2020. One team created physical training aids for safeguards courses to demonstrate two methods of nuclear fuel reprocessing. The other team developed an enrichment monitor mounting bracket that the International Atomic Energy Agency could use to help monitor uranium hexafluoride gas in enrichment facilities.

Advanced reactor development and testing could benefit from a Pacific Northwest National Laboratory innovation that combines remote, real-time monitoring of gaseous fission by-products with a software package designed with plant operators in mind, according to an article published online earlier this month.

The basics: “Real-time monitoring is a valuable tool, particularly in the development of next-generation reactors,” said Amanda Lines, a PNNL chemist. “This can help designers more efficiently and effectively design and test flow loops, mechanisms, or processes. Also, when they ultimately deploy their reactor systems, this gives operators a tool to better understand and control those processes.”
