The United States is embarking on a new coordinated federal low-dose radiation research program. With guidance from the National Academies of Sciences, Engineering, and Medicine, the Department of Energy’s Office of Science will build a program that integrates the research of past decades, but without treading the same well-worn path. Instead, the new program will focus on how the scientific understanding of low-dose radiation can best be augmented, applied, and communicated.

The Tennessee Valley Authority and nuclear technology and engineering company Kairos Power this morning announced plans to collaborate on the deployment of the latter’s low-power demonstration reactor, dubbed Hermes, at the East Tennessee Technology Park (ETTP) in Oak Ridge, Tenn. TVA will provide engineering, operations, and licensing support to help Kairos with deployment, according to the announcement.

The Nuclear Regulatory Commission has approved Dominion Energy’s application to renew the Surry nuclear power plant’s operating licenses for an additional 20 years. The renewed licenses authorize the extension of reactor operation at the two-unit plant from 60 to 80 years.

Pritzker

The office of Illinois governor J. B. Pritzker last week unveiled an ambitious energy plan for the state that includes limited subsidies for the financially ailing Byron and Dresden nuclear plants. (In August 2020, Exelon Generation announced that the two Illinois facilities would close this year—Byron in September and Dresden in November—without some form of compensation from the state, due to “market rules that favor polluting power plants over carbon-free nuclear energy.”)

The new plan, dubbed the Consumers and Climate First Act, calls for achieving 100 percent clean energy generation in Illinois by 2050 and recognizes nuclear as a means toward that end. “In the near term, the closure of nuclear plants in Illinois is likely to result in a generation gap that will be filled by dirty energy, namely fossil fuels,” the act states, adding that any support for nuclear should be “short-term and based on clearly demonstrated need.”

Peter Lyons, former Nuclear Regulatory Commission commissioner (2005–2009) and assistant secretary of energy for nuclear energy (2011–2015), has passed away.

American Nuclear Society President Mary Lou Dunzik-Gougar and executive director/CEO Craig Piercy issued the following statement on May 3:

“We are saddened to hear about the death of Peter Lyons. An ANS fellow and member since 2003, Pete will be remembered for his inspiring leadership and distinguished public service career that spanned five decades. His legacy and vision for a nuclear renaissance will continue to inspire future generations of nuclear professionals. Our thoughts today are with his family and loved ones.”

The disturbingly long list of U.S. nuclear plants prematurely closed in recent years will get even longer tonight when the last reactor at the Indian Point Energy Center, Unit 3, powers down for the final time. The shutdown, scheduled for 11 p.m. local time, will mark the end of nearly 60 years of zero-carbon electricity generation at the Buchanan, N.Y., facility.

If there is one U.S. state you might think would be on top of the nuclear-plant-retirement problem, it’s Illinois: With 11 power reactors, more than any other state, it is number one in nuclear generating capacity. In 2019, 54 percent of its in-state generation came from nuclear power. So why, at this writing in mid-April, does Illinois still face the possibility of losing two of its nuclear plants later this year?

New Jersey’s Board of Public Utilities (BPU) yesterday voted unanimously to extend, for an additional three years, the zero emission certificate (ZEC) program benefitting the state’s two operating nuclear power plants, Hope Creek and Salem. The two facilities produce more than 90 percent of New Jersey’s carbon-free electricity and about 40 percent of its overall power.

On April 26, as the ITER Organization announced that magnet assembly had begun with the April 21 placement of the divertor coil in the bottom of the machine, the organization also published an Image of the Week that bears an unmistakable—and unintentional—resemblance to the Olympic rings. The pre-compression rings were being prepped for installation in the ITER Assembly Hall when the serendipitous arrangement was captured by Bruno Levesy, a project manager at ITER.

Georgia Power yesterday announced two significant milestones at the Vogtle nuclear plant’s expansion project: the commencement of hot functional testing at Unit 3 and the placement of Unit 4’s passive containment cooling water storage tank, known as CB-20.

Construction and maintenance services firm Day & Zimmermann (D&Z) has paid $200,000 to resolve allegations that it submitted false claims to the Tennessee Valley Authority for services performed in connection with capital improvement projects at the Watts Bar nuclear plant, the U.S. Attorney’s Office for the Eastern District of Tennessee announced last week.

The decline in global carbon dioxide emissions recorded last year will not continue through 2021, a new report from the International Energy Agency concludes. Released last week, Global Energy Review 2021 finds that energy–related CO₂ emissions are on course for the second-largest increase in history, reversing most of 2020’s COVID pandemic–related drop. The surge would be the largest since 2010, during the carbon-intensive recovery from the worldwide financial crisis, according to the agency.

Is isotope science all sweetness and light? Recent headlines on research confirming the sweet taste of heavy water and the creation of the lightest isotope of uranium yet may give that impression. But the serious science behind these separate research findings has implications for human health and for the understanding of the process of alpha decay.

The Biden administration has launched an initiative to enhance the cybersecurity of U.S. electric utilities’ industrial control systems (ICS) and secure the nation’s energy sector supply chain, the Department of Energy announced on April 20. The 100-day plan is a coordinated effort between the DOE, the Cybersecurity and Infrastructure Security Agency, and the electricity industry.

When a nuclear power plant closes, here is what happens:

Thousands of people lose their jobs. The local economy nosedives. Air pollution increases. Reliance on natural gas, often bought from out-of-state, goes up. Electricity on the grid becomes less reliable with the loss of the most reliable source of power. And electric prices can even rise.

The ASME/ANS Joint Committee on Nuclear Risk Management (JCNRM) has achieved a significant milestone in the advancement of probabilistic risk assessment (PRA) technology. ANSI/ASME/ANS RA-­S-­1.4–2021 [1], Probabilistic Risk Assessment Standard for Advanced Non-­Light Water Reactor Nuclear Power Plants, has been approved by the JCNRM, the ANS Standards Board, the ASME Board of Nuclear Codes and Standards, and the American Nuclear Standards Institute.

As predictive analytical tools, artificial intelligence (AI) and machine learning (ML) show promise in improving nuclear reactor safety while offering economic savings. To get a better understanding of current usage and future trends in AI and ML in the commercial nuclear power industry, the Nuclear Regulatory Commission is seeking comments from the public, the nuclear industry, and other stakeholders, as well as other interested individuals and organizations.

Canadian Nuclear Laboratories (CNL) announced last week that it has fabricated fully ceramic microencapsulated (FCM) fuel pellets, a proprietary reactor fuel designed by Ultra Safe Nuclear Corporation (USNC) for its Micro Modular Reactor (MMR). The FCM project, funded through the Canadian Nuclear Research Initiative (CNRI), represents the first time that tristructural isotropic (TRISO) fuel has been manufactured in Canada, according to CNL.

Manchin

Highlighting nuclear’s role in providing reliable power, reducing emissions, and addressing climate change, Sen. Joe Manchin (D., W.Va.) sent a letter to President Biden, urging him to support the continued operation of the United States’ civil nuclear fleet and prevent further plant closures. Manchin, chairman of the Senate Energy and Natural Resources Committee, said that preventing the closure of existing nuclear power plants is critical to achieving emission reduction goals while ensuring a reliable grid.

Alberta Premier Jason Kenney has added his signature to a memorandum of understanding on small modular reactor development that was signed in 2019 by the premiers of New Brunswick, Ontario, and Saskatchewan. Kenney signed the document last week at a virtual event that also promoted the release of Feasibility of Small Modular Reactor Development and Deployment in Canada—a study formally requested as part of the MOU.
