Power & Operations

The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.

“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”

Constellation Energy, owner and operator of the nation’s largest reactor fleet, will ask the Nuclear Regulatory Commission to extend the operating licenses of the Clinton and Dresden reactors by 20 years, the company announced Monday, adding that it expects to file license applications with the agency in 2024.

Pacific Gas and Electric Company filed a letter with the Nuclear Regulatory Commission yesterday, officially requesting that the agency resume its review of the utility’s license renewal application for Diablo Canyon Units 1 and 2.

Computer-Guided Work

When it comes to computer-guided navigation, we look to our GPS app for seamless guidance. It provides granular, step-by-step directions while it tracks our position and progress towards our destination. It superimposes relevant information such as the location of restaurants and the lowest price gas stations on route. One of these days, it will even read us the menu of a selected restaurant on our path while placing an order as we drive towards it.

The United States and Japan have announced Winning an Edge Through Cooperation in Advanced Nuclear (WECAN)—a new agreement aimed at supporting the deployment of small modular reactors and other advanced reactor technologies in partner countries.

Managing plant source term for refueling outage cleanup and full power service can be controlled with the aid of specially macroporous resins. These ion exchange resins are often a cost-effective media for containing impurities in nuclear coolant, minimizing the release of contaminants and ionic leakage, all while encountering impact from oxidative chemistry and radiation. Macroporous resins continue to meet increased expectations in the industry and are considered among the best-accepted practices for nuclear plant source term minimization in standalone and layered polishing vessels.

Morawiecki

Poland has chosen Westinghouse Electric Company to supply the reactors for its initial nuclear power plant, as the Central European nation seeks to lessen its dependence on domestic coal and Russian imports for its energy supply. On Friday, Polish prime minister Mateusz Morawiecki announced the decision on Twitter, confirming last week’s reports that Westinghouse’s AP1000 technology was the government’s likely choice.

“A strong [Polish-American] alliance guarantees the success of our joint initiatives,” Morawiecki tweeted. “After talks with [vice president Kamala Harris and energy secretary Jennifer Granholm], we confirm our nuclear energy project will use the reliable, safe technology of [Westinghouse].”

Competing with the American firm for the job were Électricité de France and Korea Hydro & Nuclear Power. In October 2021, EDF submitted an offer to build four to six EPRs in Poland, while KHNP offered in April of this year to construct six APR1400 units.

Any method that can enhance safety, reduce risk, and lower costs is worth a second look. When that method proves it has the potential to optimize aging management at any nuclear power plant, it’s time to spread the word.

In 2019, a small team focused on selective leaching began looking for a way to use risk insights to optimize the implementation of deterministic aging management programs (AMPs). What they started soon grew into a large team effort by Constellation, Ameren, the Electric Power Research Institute (EPRI), and the Nuclear Energy Institute (NEI), along with contractors Enercon and Jensen Hughes, to develop a generic framework and then test it in two very different pilot applications.

Unit 3 at Slovakia’s Mochovce nuclear power plant achieved initial criticality on October 22, plant owner Slovenské Elektrárne has announced.

The utility started the reactor’s first fuel load September 9—after receiving in August a final authorization for commissioning from the Slovak Nuclear Regulatory Authority—and completed the process three days later.

Nuclear technology firm TerraPower and utility partner PacifiCorp have launched a study to evaluate the feasibility of deploying up to five additional Natrium reactor and integrated energy storage systems in the utility’s service territory by 2035, the companies announced yesterday. (PacifiCorp’s business units—Pacific Power and Rocky Mountain Power—serve customers in California, Oregon, and Washington, and in Idaho, Utah, and Wyoming, respectively.)

Canada Infrastructure Bank (CIB) has finalized an agreement with Ontario Power Generation, committing C$970 million (about $715 million) to Canada’s first small modular reactor, to be located at OPG’s Darlington nuclear power plant in Clarington, Ontario.

A state-owned enterprise founded in 2017, CIB is charged with financially supporting revenue-generating infrastructure projects in the public interest via public-private partnerships. The agreement with OPG is the bank’s largest investment in clean power to date, according to a Tuesday joint announcement.

Following a meeting in Washington, D.C., on Sunday with secretary of energy Jennifer Granholm, Polish deputy prime minister Jacek Sasin told reporters that his nation is close to choosing the reactor supplier for its initial nuclear plant project, adding, according to Bloomberg, “There is a big chance that we will finally pick Westinghouse.”

And in a news release on the meeting from the Polish government, Sasin is quoted as saying, “The massive energy crisis that is currently affecting us means that we must quickly make decisions on building the country’s energy security based on new, clean, cheap, and reliable sources, and such a source is nuclear energy. We want the decisive decisions to be made as soon as possible. That is why we asked [Granholm] for a meeting, during which we will clarify all the issues that remain to be clarified.”

NuScale Power announced October 20 that the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) issued a letter the previous day agreeing with NRC staff’s approval of NuScale’s methodology for determining the plume exposure pathway emergency planning zone (EPZ). As approved, the methodology would permit a smaller EPZ—dependent on site-specific conditions, including seismic hazards—that provides the same level of protection to the public as the 10-mile radius EPZs used for existing U.S. nuclear power plants.

In case anyone forgot, Russia can build nuclear power plants, not just occupy them—as discussed a week ago on Newswire. Last week in Bangladesh, workers completed the installation of the reactor pressure vessel (RPV) for the second unit at the Rooppur construction site.

The International Atomic Energy Agency has released this year’s edition of Country Nuclear Power Profiles (CNPP), an annual report providing background information on the status and development of IAEA member states’ nuclear power programs. It contains historical information for 50 countries, including 30 with operating plants and 20 with past or planned programs.

This year, Nuclear Science Week was October 17–21, and the ANS Young Members Group celebrated by hosting the virtual event “Nuclear Entrepreneurship” on October 18. Panelists were Per Peterson, cofounder and chief nuclear officer of Kairos Power; Robbie Stewart, cofounder of Boston Atomics; Kelsey Souza, chief operating officer of Ultra Safe Nuclear; and Tyler Bernstein, chief executive officer of Zeno Power. The event was moderated by Brett Rampal, director of nuclear and power strategy at Veriten and chief technical analyst at Segra Capital Management.

German chancellor Olaf Scholz has provided what appears to be the final word on the fate of his country’s three remaining operating nuclear power plants.

Via an October 17 letter, Scholz informed economy and energy minister Robert Habeck, environment minister Steffi Lemke, and finance minister Christian Lindner of his decision to keep all three facilities operating “beyond 31 December 2022 until 15 April 2023 at the latest.” The order ends months of argument between Scholz’s two coalition partners—the stridently antinuclear Greens and the center-right Free Democrats (FDP)—regarding the plants’ continued operation. (Habeck and Lemke are Green Party members, while Lindner is with the FDP.)

Finnish energy company Fortum has announced the launch of a two-year feasibility study to explore the potential for new nuclear construction, with a focus on Finland and neighboring Sweden. The utility said it will examine commercial, technological, and societal conditions for both conventional large reactors and small modular reactors.

Gov. Whitmer

While the fate of Michigan’s Palisades nuclear plant remains uncertain, Gov. Gretchen Whitmer has approved legislation requiring a feasibility study to examine the potential for new nuclear generation in the state.

Signed into law last Friday, House Bill 1609 instructs the Michigan Public Service Commission to engage an outside consulting firm to conduct the study.

The measure was introduced in the House on April 14 by Rep. Graham Filler (R., 93rd Dist.) and passed that chamber on May 19, 85–20. On September 28, the bill passed even more comfortably in the Senate, 32–4.

The mandated study is due to the governor and leaders of the state legislature in 18 months.

Arguably, nowhere does a more robust safety culture exist than in nuclear, an industry that is a model of a learning organization, dedicated to continuous improvement through transparency in identifying and correcting errors and failures. Over the course of maintenance and outage planning, the cornerstones of reactor safety are considered in every decision regarding maintenance and outage activities. Radiation monitoring systems in nuclear power plants are vital to plant safety and regulatory compliance. In addition to the 10 CFR 20 applications, the industry relies on radiation monitors for measuring effluents (RG 1.21, RG 4.15, and Part 50 App A GDC 64), reactor pressure boundary leakage (RG 1.45), and PWR primary to secondary leakage, and to assist in emergency classification (RG 1.97). The Nuclear Regulatory Commission’s well-intended Maintenance Rule places maintenance priorities on systems, structures, and components (SSCs) used to mitigate accidents and SSCs used in emergency operating procedures (EOPs). The Maintenance Rule also includes SSCs whose failure could prevent a safety-related SSC from fulfilling its safety-related function and SSCs whose failure could cause a reactor scram or actuation of a safety-related system. Unfortunately, the narrow scope of the Maintenance Rule leaves a significant portion of radiation monitoring systems outside the scope of the rule, which often delays repairs.
