Power & Operations

Southern Company subsidiary Georgia Power on January 11 announced yet another delay to the startup of the Unit 3 reactor at the Vogtle nuclear power plant. It’s the latest in a long series of delays to the two-unit construction project at the Waynesboro, Ga., site. (Vogtle-3 was initially supposed to enter service in 2016.)

The Michigan Public Service Commission has requested proposals for a feasibility study on nuclear power generation in the state. Responses to the January 5 request are due January 19, with the proposals themselves due February 3. The selected firm is to deliver a report to Michigan’s governor and leaders of the state’s legislature by April 2024.

NuScale Power has announced its submission to the Nuclear Regulatory Commission of a standard design approval application for its updated small modular reactor design, which is based on a six-module VOYGR plant configuration powered by an uprated 77-MWe module.

Applications for grants from Britain’s nuclear fuel fund are now being accepted, the U.K. Department for Business, Energy and Industrial Strategy (BEIS) announced Monday. The application deadline is February 20.

Portland, Ore.–based NuScale Power yesterday announced the signing of a contract with Romania’s RoPower Nuclear for front-end engineering and design (FEED) work that, according to the American company, marks “a significant step toward the deployment of a NuScale VOYGR small modular reactor power plant in Romania.” The contract was signed on December 28.

Small modular reactor developers Holtec International and GE Hitachi Nuclear Energy (GEH) are both looking to the United Kingdom as a prime location for deployment of their units—the SMR-160 and BWRX-300, respectively.

On December 19, Holtec Britain announced that it is poised to enter the United Kingdom’s generic design assessment (GDA) process for the SMR-160 early in 2023, enabling the start of construction of the first U.K. unit as soon as 2028. (The GDA, developed by the Office for Nuclear Regulation and the Environment Agency, gauges the safety, security, and environmental protection aspects of a nuclear plant design. Successfully completing the assessment culminates in a design acceptance confirmation from ONR and a statement of design acceptability from the Environment Agency.)

In the 1960s, nuclear energy established itself as a mainstay of the electrical grid for its ability to produce carbon-­free, safe, and reliable power. Indeed, nuclear energy currently provides about 50 percent of carbon-­free electricity in the United States, but a major challenge is its cost.

The U.K. government has announced £77 million (about $93 million) in new funding to support the development of the next generation of advanced nuclear reactors in Britain and to boost the nation’s nuclear fuel production.

Holtec International is apparently not ready to give up on the Palisades nuclear power plant just yet. Despite having been denied federal funds last month for a possible reopening of the Covert, Mich., facility, the company this week announced its intention to reapply.

Westinghouse Electric Company and Polish utility Polskie Elektrownie Jądrowe have signed an agreement defining the main principles and path forward for Poland’s first nuclear power reactors, the companies jointly announced last week.

The agreement, signed December 15, outlines next steps for the project, including site layout, licensing and permitting support, and site development services and procurement, and establishes the framework for future project delivery contracts. Another agreement is expected to be signed by mid-2023 for the design of the facility.

Context: In October, Poland chose Westinghouse to supply the reactors for its first nuclear power plant, as the Central European nation seeks to lessen its dependence on domestic coal and Russian imports for its energy supply. Competing with Westinghouse for the job were Électricité de France and Korea Hydro & Nuclear Power.

A bipartisan group of senators sent a letter last week to Scott Nathan, chief executive officer of the U.S. International Development Finance Corporation (DFC), urging the agency to begin financing nuclear energy projects and support the continued development and deployment of advanced nuclear technology.

Signing the December 8 letter were Sens. John Barrasso (R., Wyo.), Cory Booker (D., N.J.), Shelley Moore Capito (R., W.Va.), Ben Cardin (D., Md.), Chris Coons (D., Del.), Kevin Cramer (R., N.D.), Joe Manchin (D., W.Va.), Lisa Murkowski (R., Alaska), and Jim Risch (R., Idaho).

Since the inception of commercial nuclear power in the United States, every control room in every nuclear plant has looked essentially the same. You will see fixed alarm tiles, red and green lights, rows of switches, and analog meters. Until about a decade ago, you would even have seen paper charts (now replaced by digital versions of those same charts). Licensed operators have shown through a proven operating history that this control room design is safe and effective. Genius definitely went into the complexity of circuits and placement of switches and indications in the design, but things have come a long way over the years, and new technology, updated plant designs, and the need to improve efficiency and maintain reliability have impacted staffing and the role of operators. A control room update is long overdue. So, what lies ahead for the future of nuclear control room design? What possibilities exist for the next generation of plants?

While it currently has the lowest installed nuclear capacity of any nuclear-powered nation in Europe with one 482-MWe pressurized water reactor at Borssele, the Netherlands has in recent years been looking to move up in the rankings.

Meteorological winter is here, and a chill is gripping northern Europe. Predictably, renewable generation has entered a seasonal lull and heating demand is up, despite a push to conserve natural gas, which means electricity and gas bills are up too. With a grudging nod to reality, German chancellor Olaf Scholz ensured in October that Germany’s three remaining nuclear power reactors will provide a few more months of clean, reliable power. Their premature closure, once scheduled for December 31, is now expected by April 15, 2023.

In late 2015, we heard rumors that Diablo Canyon was under threat of premature closure. As details emerged, we realized the situation was dire—similar stories were emerging around the country and the world. Nuclear plants were shutting down early for reasons that had nothing to do with plant conditions or operations, but because of politics and poor public perception.

We started brainstorming possible ways we could help, then realized our efforts had to be about more than just one plant. We knew we were in a bit of a unique position. There aren’t a whole lot of women in our industry—­especially not hippie environmentalist moms. Our story is interesting in that we were initially skeptical about nuclear power, asked questions over many years, and eventually changed our minds to support it.

Unit 1 at South Korea’s Shin-Hanul nuclear power plant entered commercial operation last week, Korea Hydro & Nuclear Power has announced. The 1,340-MWe APR-1400—designed by KHNP and parent firm Korea Electric Power Company—achieved initial criticality on May 22 of this year and was connected to the grid on June 9.

Cold hydro testing of Unit 4 at the Vogtle plant’s nuclear expansion site has been completed, Georgia Power announced on December 7.

The Nuclear Regulatory Commission has docketed Vistra Corporation’s license renewal application for the Comanche Peak reactors.

Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, the Comanche Peak plant is home to two pressurized water reactors. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.

For years the U.S. nuclear industry has done an outstanding job keeping plant availability high while simultaneously continuing to improve safety and economics. With capacity factors averaging more than 90 percent, you would think that no one would shut down an operational nuclear power plant. But that is what we have seen in a number of cases. Fortunately, this now seems to be changing. As I write this column, Diablo Canyon’s new life extension application has just been submitted to the Nuclear Regulatory Commission for review, and the Department of Energy’s program to support continued operation of nuclear power plants is providing hope that current plants will continue to have the opportunity to demonstrate their operational excellence.

How did we get here? When I ask this question—both of myself and the industry as a whole—I envision this as two sides of the same coin. Through the efforts of many we have improved our financial and economic viability, but challenges remain because the full value proposition of nuclear energy has not been realized.

The British government has announced an investment of £679 million (about $828 million) in the proposed Sizewell C nuclear plant in Suffolk, England, confirming chancellor of the exchequer Jeremy Hunt’s remarks on the project in his November 17 Autumn Statement.
