The promise of hydrogen fusion as a safe, environmentally friendly, and virtually unlimited source of energy has motivated scientists and engineers for decades. For the general public, the pace of fusion research and development may at times appear to be slow. But for those on the inside, who understand both the technological challenges involved and the transformative impact that fusion can bring to human society in terms of the security of the long-term world energy supply, the extended investment is well worth it.

Failure is not an option.

Largely as a result of the continuing COVID-19 crisis, the Vogtle reactor-construction project team expects to further adjust dates for achieving key project milestones, including the start of hot functional testing and fuel load for Unit 3, Southern Company subsidiary Georgia Power announced on January 11.

The company added, however, that it continues to expect to bring Unit 3 into service this November and Unit 4 into service in November 2022. Additional updates on the project will be provided during Southern’s quarterly earnings call next month.

The Department of Energy launched a 14-day public review and comment period on January 11 on a draft environmental assessment for a proposal to construct the Microreactor Applications Research Validation & EvaLuation (MARVEL) project microreactor inside Idaho National Laboratory’s Transient Reactor Test (TREAT) Facility.

The basics: The MARVEL design is a sodium-potassium–cooled thermal microreactor fueled by uranium zirconium hydride fuel pins using high-assay, low-enriched uranium (HALEU). It would be a 100-kWt reactor capable of generating about 20 kWe using Stirling engines over a core life of about two years.

The DOE proposes to install the MARVEL microreactor in a concrete storage pit in the north high bay of the TREAT reactor building. Modifications to the building to accommodate MARVEL are anticipated to take five to seven months. Constructing, assembling, and performing preoperational testing are expected to take another two to three months prior to fuel loading.

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.

Baranwal

Rita Baranwal, the Department of Energy’s assistant secretary for the Office of Nuclear Energy, announced today via Twitter that she will be leaving her position at the end of the day. “It has been an absolute honor to serve in this capacity to help advance our U.S. nuclear energy R&D,” she tweeted. “I plan to continue to use my talents to promote, lead, and advance our nation’s largest source of clean energy so that our nation and my family will have a cleaner and more sustainable planet to protect.”

Baranwal previously directed the Gateway for Accelerated Innovation in Nuclear (GAIN) initiative at Idaho National Laboratory. Before joining the DOE, Baranwal served as director of technology development and application at Westinghouse. She is a Fellow of the American Nuclear Society.

From the time we discovered how the sun produces energy, we have been captivated by the prospect of powering our society using the same principles of nuclear fusion. Fusion energy promises the bounty of electricity we need to live our lives without the pollution inherent in fossil fuels, such as oil, gas, and coal. In addition, fusion energy is free from the stigma that has long plagued nuclear power about the storage and handling of long-lived radioactive waste products, a stigma from which fission power is only just starting to recover in green energy circles.

• Defense Department invests in three microreactor designs: Three reactor developers got a boost on March 9 when they each were awarded a contract from the U.S. Department of Defense to design a reactor that can fit inside a standard shipping container for military deployment. Read more.

Adequate uranium resources exist to support the long-term, sustainable use of nuclear energy for low-carbon electricity generation, as well as for other applications, including hydrogen production. That assessment is contained in the latest (28th) edition of Uranium—Resources, Production and Demand, a global, biennial reference prepared jointly by the OECD Nuclear Energy Agency and the International Atomic Energy Agency.

The publication adds, however, that the impact of the COVID-19 pandemic and recent reductions in uranium production and exploration could affect available supplies, suggesting that timely investment in innovative mining and processing techniques would help assure that uranium resources are brought to market when needed.

Bulgaria has become the 34th member of the Paris-based OECD Nuclear Energy Agency (NEA). With its several decades of experience operating VVER units, Bulgaria will reinforce the NEA’s capacity to address matters related to pressurized water reactor technologies and their operational characteristics, according to the NEA on January 4.

In addition, the NEA said that it will support Bulgaria’s efforts in technical and policy areas, including work to address nuclear skills capacity building, the development and application of nuclear data and simulation codes, and issues related to radioactive waste management, decommissioning, and nuclear economics.
