While the construction of two additional reactors at Slovakia’s Mochovce nuclear plant (Units 3 and 4) may get most of the attention, it isn’t the only major project underway there. In October of last year, plant owner Slovenské Elektrárne commenced the first phase of an effort to revitalize two of the four 125-meter-tall, Iterson-type cooling towers that serve the facility’s two operating reactors—both of which began generating electricity in the late 1990s. Towers #11 and #21 had been refurbished in 2011 and 2012, respectively. The other two, however, towers #12 and #22, had never undergone refurbishment.

The U.K. government has granted a development consent order (DCO) for EDF Energy’s proposed Sizewell C plant near Leiston in Suffolk, moving the new nuclear build project closer to a reality.

Nuclear New Build (NBB) Generation Company, an EDF Energy subsidiary, submitted the DCO application to the government’s Planning Inspectorate in May 2020, setting out the range of measures the project would implement to mitigate construction effects and maximize community benefits. The Planning Inspectorate accepted the application in June 2020 and completed its examination in October 2021. Recommendations were made to the secretary of state for business, energy, and industrial strategy this February.

Westinghouse has signed a new contract with Energoatom, Ukraine’s state-owned nuclear utility, to provide technical information in support of Energoatom’s feasibility study update for the construction of two Westinghouse AP1000 reactors at the Khmelnytskyi nuclear power plant in Ukraine.

The contract, according to Westinghouse’s announcement, advances the previously signed agreement between Westinghouse and Energoatom for the construction of two of the Generation III+ reactors at Khmelnytskyi Units 5 and 6.

Ontario Power Generation has updated its Green Bond Framework to include nuclear energy in recognition of the role the technology stands to play in helping the company reach its decarbonization goals. (OPG’s climate change plan, established in 2020, commits the firm to achieving net-zero carbon emission status by 2040.)

The green bonds issued by the utility and its subsidiaries are used to finance and/or refinance certain energy projects and support the development of clean technologies.

South Korea’s new president, Yoon Suk-yeol, appears to be following through on his campaign pledge to reverse the previous administration’s domestic nuclear phaseout plan. Earlier this month, Yoon’s Ministry of Trade, Industry, and Energy announced a new direction for the nation’s energy policy—one that calls for, among other things, a reembrace of nuclear power. A further announcement on the subject last week provided additional details.

In the western part of Michigan, where I grew up and spent the early part of my career, water availability was rarely a concern or a topic that might appear in the news. Lake Michigan was a plentiful source of water, and Mother Nature always provided plenty of precipitation to keep things green. If anything, sometimes folks wished it would stop raining! So it was quite a big change in environment when in 2008 my career took me to the desert of Arizona and the Palo Verde Generating Station, with annual regional rainfall totals of three inches in a good year.

U.K.-based reactor developer Rolls-Royce SMR last week announced a list of six potential sites for its first small modular reactor factory. According to the company's announcement, the factory—the largest and most complex of three such facilities envisioned by the company—will manufacture the SMR vessels.

NuScale Power and Paragon Energy Solutions have signed a patent license agreement that will make NuScale’s Nuclear Regulatory Commission–approved reactor protection system architecture available to the broader nuclear industry, the two companies announced on July 12.

Known as the Highly Integrated Protection System (HIPS) platform, the system was developed by NuScale and Rock Creek Innovations (RCI), a hardware supplier of commercial nuclear protections systems, over six years of collaboration that began in 2010. Paragon, a supplier of safety-related parts and components, acquired RCI in December 2021.

The Egyptian Nuclear and Radiological Regulation Authority (ENRRA) recently issued the construction permit for the first of four proposed Russian-designed and -supplied reactors at Egypt’s El Dabaa site, located on the Arab nation’s Mediterranean coast, about 185 miles northwest of Cairo.

An application for the permit was submitted by Egypt’s Nuclear Power Plants Authority (NPPA)—the public entity charged with operating the plant—in June of last year.

As part of its strategy to achieve net-zero status by 2050, the Tennessee Valley Authority yesterday issued a request for proposals for supplying up to 5 GW of carbon-free energy that must be operational before 2029.

Water is necessary for life, and in our current nuclear industry, it is necessary for continuing operations. Whether to enable sustainable fission, provide cooling during normal or emergency plant operations, or support radioactive decontamination processes, water is relied on as much as any other commodity to keep the nuclear power industry going. Even though it has played a big part over the past six decades of commercial nuclear power operations, the need for innovation in water management is a top priority.

First, we have to have it

It’s well-known that the western U.S. is currently seeing some of the worst drought conditions in recent history. Maintaining a dependable (and affordable) water supply is key for our existing nuclear facilities to keep operating. Several of the drought-affected locations will need to find ways to make use of what is there or find an alternative—and alternatives to water are not that easy to come by. As we look to the next generation of reactor types, many have reduced reliance on water, but this is not the solution in the near term. Our best plan, then, is to find ways to use less of an increasingly diminished resource through integrating new and existing technology so we can get by with what is available.

Moore

“Nuclear energy is the safest of all the electricity technologies we have.” This statement by Patrick Moore, former director of Greenpeace in a recent interview on NewsNation’s “Special Report,” is at odds with the position of the environmental organization he helped found.

New EU taxonomy: Moore did the interview in the wake of the European Parliament’s controversial action to support the addition of nuclear energy and natural gas to the European Union’s taxonomy of environmentally sustainable, green technologies. In response to that action, Greenpeace announced that it would submit a formal request to the European Commission to review the move and, if necessary, mount a legal challenge to the action with the European Court of Justice.

Nesbit

Steven Nesbit, ANS’s immediate past president, is among the nuclear industry leaders quoted in a recent New York Times article about the renewed interest in nuclear power in the United States. The article explains that the challenges of meeting clean energy goals and surging electricity demands are prompting many government officials to take “a fresh look at nuclear power—both extending the life of existing reactors and building new ones.” The article also presents the views of some nuclear critics.

Much of the article focuses on the fate of California’s Diablo Canyon nuclear power plant, which is currently scheduled for shutdown in 2025. Several of the state’s lawmakers who previously supported the shutdown, including Gov. Gavin Newsom and Sen. Diane Feinstein, are now considering supporting the extended life of the plant. A joint study by Stanford University and the Massachusetts Institute of Technology has concluded that a 10-year extension of Diablo Canyon could substantially reduce carbon emissions, lessen reliance on natural gas, cut electricity costs, and minimize the risk of brownouts.

Vattenfall has initiated a study to look into the feasibility of building at least two small modular reactors adjacent to its Ringhals nuclear power plant, the Swedish state-owned power company announced recently.

Located on Sweden’s west coast about 37 miles south of Gothenburg, Ringhals holds two operating power reactors: Unit 3, a 1,074-MWe pressurized water reactor; and Unit 4, a 1,130-MWe PWR. The facility is also home to two retired units: Unit 1, a boiling water reactor shut down in December 2020; and Unit 2, a PWR taken off line in December 2019.

The electric utility industry has set ambitious environmental, social, and governance (ESG) goals, with most aiming to achieve carbon neutrality by midcentury by reducing greenhouse gas emissions. Nuclear power can be a key technology in the clean energy portfolio to reach this goal, and small modular reactors can aid the industry’s efforts in meeting ESG goals through protection and conservation of water resources.

The French government plans to fully nationalize the debt-laden Électricité de France, the sixth largest publicly traded company in France and operator of the 56-unit French nuclear reactor fleet. Currently, EDF is 84 percent state owned.

The state of California recently and quite sensibly cracked the door back open for continued operation of the Diablo Canyon nuclear power plant past the current operating license expiration dates in 2024 (Unit 1) and 2025 (Unit 2). The nonprofit North American Electric Reliability Corporation’s recently released 2022 Summer Reliability Assessment highlights the risk of electricity shortages in California. Given that concern, as well as the benefits of continued Diablo Canyon operation—including much needed clean, reliable energy; good jobs; and potential for large-scale production of fresh water—another look at the shutdown decision made several years ago is clearly warranted. Sen. Dianne Feinstein (D., Calif.) reinforced this point when she added her voice to the growing chorus of policymakers advocating extended operation for Diablo Canyon.

With the proper investment and policy support, advanced nuclear energy has the potential to become a key component of a future U.S. clean energy system, a new report from Berkeley, Calif.’s, Breakthrough Institute finds.

Released this morning, the 155-page Advancing Nuclear Energy: Evaluating Deployment, Investment, and Impact in America’s Clean Energy employs “a high-resolution nationwide model of the United States electricity sector to demonstrate how advanced nuclear reactors might play a major role in a least-cost plan to transition the power grid entirely to clean energy sources by 2050, assuming that the first advanced reactors are available for deployment by 2030,” according to the executive summary.

The decision by the Department of Energy to revise its Civil Nuclear Credit Program—easing the path toward program qualification for California’s Diablo Canyon—was not the only promising news last week for advocates of the state’s sole operating nuclear power facility. On June 30, California Gov. Gavin Newsom signed legislation that could provide funding for Diablo Canyon in the event the state decides to keep the plant in operation beyond its slated 2025 closure date. Also in line for possible life extension under the measure are some of Southern California’s fossil fuel plants.
