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.

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.

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.

Reyes

José Reyes, cofounder and chief technology officer at small modular reactor developer NuScale Power, touted the potential of the firm’s technology to help solve the nuclear industry’s cost-overrun issues in an interview yesterday with Yahoo Finance. (At up to 77 MWe gross, the NuScale Power Module is the smallest of the light-water SMRs in development.)

Speaking with journalist Akiko Fujita, Reyes, an ANS member since 1977, also touched on nuclear’s role in addressing the issue of climate change.

The eight-minute discussion is available online, along with the interview transcript.

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.

A research and consulting firm hired by Illinois governor J. B. Pritzker’s administration to scrutinize the financial fitness of Exelon’s Byron and Dresden nuclear plants approves of limited state subsidies for the facilities, according to a redacted version of the firm’s report made available yesterday.

Black

Missouri has only one nuclear power plant, Ameren Missouri’s single-unit Callaway facility. State Rep. John Black (R., 137th Dist.) doesn’t think that’s enough.

Black’s H.B. 261, introduced earlier this year after a similar version failed to make headway in 2020, would create the Missouri Nuclear Clean Power Act, aimed at fostering the development of nuclear power in the state. Under the bill, companies that build clean baseload generating plants or renewable-source generating plants rated at 200 MW or more would no longer be prohibited from charging for construction costs before beginning operation.

With a blunt but indisputably accurate headline, an article from yesterday’s New York Times on the imminent closure of Indian Point makes it immediately clear what will happen when Unit 3, the nuclear plant’s last operating reactor, is shut down at the end of this month: The state of New York will be forced to rely more heavily on fossil fuels for electricity generation.

Following the retirement of Indian Point-2 last April, the share of New York’s power coming from gas-fired plants rose to about 40 percent, from about 36 percent in 2019, the piece notes, adding that the share from renewables moved up only slightly, to about 30 percent.

Moran

Coons

Sens. Chris Coons (D., Del.) and Jerry Moran (R., Kan.) late last month reintroduced legislation to give investors in clean energy projects, including advanced nuclear, access to a tax advantage currently available only to fossil fuel investors. The bipartisan bill, the Financing Our Energy Future Act (H.B. 1034), was initially introduced in June 2019.

The measure would enable clean energy companies to form master limited partnerships (MLPs)—business ventures that combine the tax benefits of private partnerships (where profits are taxed only when investors receive distributions) with the liquidity of publicly traded companies. By statute, MLPs are currently available only to investors in energy portfolios for oil, natural gas, coal extraction, and pipeline projects.

The Nuclear Regulatory Commission on April 6 issued a violation notice and proposed a $150,000 civil penalty to Florida Power & Light Company for falsifying plant records and recording inaccurate data in maintenance records at its Turkey Point nuclear power plant near Homestead, Fla.

An atomic safety and licensing board has been established to address a hearing request filed on behalf of an antinuclear group regarding the subsequent license renewal (SLR) application for NextEra Energy’s Point Beach reactors, located near Two Rivers, Wis. The Nuclear Regulatory Commission published notice of the panel’s formation in the April 2 Federal Register.

New research indicates that small modular reactors have the potential to deliver cost-effective emission reductions in Canada’s heavy-industry sector. The research was conducted by consulting firms EnviroEconomics and Navius Research, with support from the Canadian Nuclear Association and the Canadian Nuclear Industry SMR Secretariat, along with the CANDU Owners Group.

Researchers explored a variety of cost and technical assumptions for deploying SMRs. Across all scenarios, SMRs delivered low-cost emission reductions, driving down the cost of getting Canada to net zero by 2050—a stated goal of the Trudeau administration. With deployments set to begin as early as 2026, SMRs could be widespread by 2035 as the demand increases rapidly for reductions in the industrial sector, according to the researchers.

The University of Illinois Student Section and Chicago Local Section of the American Nuclear Society hosted a webinar, The Role of Nuclear Power in Illinois, on Wednesday, March 31. The webinar provided information for state lawmakers and the general public about the potential consequences of closing the Byron and Dresden Generating Stations, two of the nuclear power plants in the state of Illinois.

The webinar recording has been archived and is available for viewing for free at the above link.

Unit 1 at the United Arab Emirates’ Barakah nuclear power plant has entered commercial operation and is now providing “constant, reliable, and sustainable electricity around the clock,” the Emirates Nuclear Energy Corporation (ENEC) announced this morning. ENEC added that, as a result of the event, the company now leads the largest decarbonization effort of any industry in the UAE.

Holtec International’s SMR-160 is a pressurized light-water thermal spectrum reactor that relies on natural circulation, thereby eliminating the need for reactor coolant pumps during normal operation. The reference design incorporates a lower pressure conventional steam turbine and wet cooling via a tube-and-shell condenser coupled with forced-draft cooling towers. Optionally, the plant can use dry cooling via Holtec’s HI-KOOL air-cooled condenser.

Building the nation’s first advanced reactor is the goal of a partnership formed between X-energy, Energy Northwest, and the Grant County (Washington) Public Utility District (PUD).

The TRi Energy Partnership will support the development and demonstration of X-energy’s Xe-100 high-temperature gas reactor, which was selected by the Department of Energy for a cost-shared commercial demonstration by 2027 through the DOE’s Advanced Reactor Demonstration Program (ARDP). The new partnership was announced on April 1, when Clay Sell, X-energy’s chief executive officer; Brad Sawatzke, Energy Northwest’s CEO; and Kevin Nordt, the Grant County PUD’s CEO, met in Richland, Wash., to sign a memorandum of understanding.

Ontario Power Generation’s Centre for Canadian Nuclear Sustainability (CCNS) will collaborate with nuclear technology firm Moltex Energy on a project aimed at recycling used fuel from CANDU reactors, the electricity generator announced March 30.

The CCNS will provide C$1 million (about $800,000) in funding to assist Moltex in demonstrating the technical viability of its process to recycle used CANDU fuel. That process, known as WAste to Stable Salt (WATSS), has the potential to reduce storage needs for used fuel, according to Moltex.

The Nuclear Regulatory Commission will discuss the 2020 safety performance of Duke Energy’s Catawba, McGuire, and Oconee nuclear power plants during a virtual meeting to be held on April 1.

The meeting will begin at 5 p.m., eastern time, with a presentation by the NRC staff responsible for plant inspections. Following the discussion with Duke Energy, questions will be answered by the NRC, including by the resident inspectors.

The public and media can access the meeting via Teams. For those without access to Teams, the telephone conference number is 301-576-2978, passcode 71391471#.

The annual assessment letters for the Catawba plant, the McGuire plant, and the Oconee plant, which include upcoming inspection plans for the plants, are available on the NRC website.

Current performance information for Catawba-1, Catawba-2, McGuire-1, McGuire-2, Oconee-1, Oconee-2, and Oconee-3 is available and updated quarterly.

A recent U.S. Energy Information Administration report, Short-Term Energy Outlook, notes that in 2020, nuclear power plants generated more electricity in the United States than coal-fired plants for the first time ever. Last year also marked the first time that coal generation was not the first or second largest U.S. electricity producer in more than 70 years.

Two factors led to the decrease in coal-fired generation, according to the EIA: one is the drop in the number of operating coal-fired plants, and the other is the lower utilization of those remaining coal-fired plants as the nation moves toward cleaner energy production. Coal, however, is not to be abandoned yet, according to the EIA.

The next couple of years will see changes in energy production, according to the EIA report. The EIA believes that "increases in natural gas prices will make coal more competitive in the electric power sector. This expected increase in coal's utilization more than offsets the upcoming retirement of 2.8 GW of coal capacity in 2021 and another 8.5 GW in 2022," based on information reported to the EIA by coal-fired plant owners and developers.

The Canadian government has awarded C$50.5 million (about $40.2 million) to Moltex Energy Canada to support small modular reactor research and technology development in New Brunswick. The investment, announced March 18, was provided by the government’s Strategic Innovation Fund and its Regional Economic Growth Through Innovation program, part of the Atlantic Canada Opportunities Agency (ACOA).

In a press release on the funding, Moltex said it plans to build the world’s first 300-MW Stable Salt Reactor–Wasteburner (SSR–W) and WAste to Stable Salt (WATSS) facility at the Point Lepreau Generating Station site in Saint John, New Brunswick, and provide electricity to the grid by the early 2030s. According to the company, its WATSS process, which recycles existing used nuclear fuel, has the potential to reduce storage needs for that fuel.
