Power & Operations

A recent article on a radio station website about an auxiliary feedwater (AFW) pump problem at the Diablo Canyon nuclear power plant led to information exchanges between a reporter, the American Nuclear Society, and nuclear advocates. The incident also involved a tweet by a member of the Union of Concerned Scientists.

An International Atomic Energy Agency team of experts has completed its review of the long-term operational safety of South Africa’s Koeberg nuclear power plant, which is operated by the public utility Eskom.

Ukraine’s nuclear operator, Energoatom, announced yesterday that the Russian military has withdrawn from the Chernobyl plant and surrounding area. “According to the staff of the Chernobyl nuclear power plant, there are now no outsiders on-site,” Energoatom stated in an online post. Russian forces took control of Chernobyl on February 24, day one of the invasion.

In a separate post, the company said that the Russians had formally agreed to return the responsibility for Chernobyl to Ukraine. It shared a scan of a document, with the heading “Act of acceptance and transfer of protection of the Chernobyl nuclear plant,” purportedly signed by a representative of Russia’s National Guard, a representative of Rosatom, Russia’s state atomic energy corporation, and a Chernobyl plant shift manager.

The governments of four Canadian provinces—Ontario, New Brunswick, Saskatchewan, and Alberta—have published a plan outlining the path forward for the advancement of small modular reactors, which could provide the nation with safe, reliable, and zero-emissions energy and create new export opportunities.

The 60-page document, A Strategic Plan for the Deployment of Small Modular Reactors, builds on an SMR feasibility study conducted under a memorandum of understanding signed in 2019 by the premiers of Ontario, New Brunswick, and Saskatchewan and in 2021 by the premier of Alberta. Prepared by Ontario Power Generation, Bruce Power, New Brunswick Power, and SaskPower, the study concluded that SMR development would support domestic energy needs, curb greenhouse gas emissions, and position Canada as a global leader in clean technologies and the fight against climate change.

On March 4, Russian forces set fire to an office building at Ukraine’s Zaporizhzhia nuclear power plant, raising fears about reactors being damaged. The attack stirred up memories of the Chernobyl accident in 1986, a reaction that longtime nuclear opponents are taking advantage of to rekindle their cause. However, the reactors operating in Ukraine today are profoundly different from the design used at Chernobyl, and are, by nature, difficult to damage.

Let’s set the record straight and explain the risks of nuclear power plants in war zones.

The Fuqing nuclear plant’s Unit 6, one of two Chinese-designed and -developed Hualong One reactors at the site, has entered commercial operation, China National Nuclear Corporation (CNNC) announced on March 25. The milestone was reached some 14 months after the reactor’s twin, Fuqing-5, became the first Hualong One in the world to enter commercial operation.

Also known as the HPR1000, the Hualong One is a 1,000-MWe Generation III pressurized water reactor that incorporates design elements of CNNC’s ACP1000 and China General Nuclear Power Group’s ACPR1000+.

The trend of big-tech billionaires of Silicon Valley investing in next-generation nuclear energy startup companies continues. In a March 22 article on the Bloomberg website, Lizette Chapman, of the site’s venture capital group, writes that these investors view nuclear power as “a solution to both cutting carbon emissions and weaning the world off now-controversial Russian gas.”

Unit 2 at the United Arab Emirates’ Barakah nuclear power plant has entered commercial operation, Emirates Nuclear Energy Corporation (ENEC) announced on March 24. Unit 2 adds an additional 1,400 MW of zero-carbon emission electricity to the UAE’s national grid, bringing the total amount of electricity produced at Barakah to 2,800 MW.

The United States and the Philippines recently signed a memorandum of understanding on strategic civil nuclear cooperation to help boost the development of the latter’s nuclear energy program.

“Many states have made carbon dioxide–reduction plans with no hope of success. But if they want to meet even a portion of those goals, they must put nuclear power back on the table.” So opined Tim Cavanaugh, senior editor at the Mackinac Center for Public Policy, in an essay published by The Hill on March 23.

In keeping with the ringing endorsement of nuclear energy it gave in January, the Czech Republic continues moving forward with plans for new reactor construction.

International Atomic Energy Agency director general Rafael Mariano Grossi said on Wednesday that he remains “gravely concerned” about Ukraine’s nuclear sites amid the ongoing Russian invasion and stressed the urgency of reaching an agreement on a framework that would enable his agency to provide technical assistance to ensure the safe and secure operation of those facilities.

Wilmington, N.C.–based GE Hitachi Nuclear Energy has signed a memorandum of understanding with Kärnfull Next—a new company and a wholly owned subsidiary of Swedish firm Kärnfull Future AB—to collaborate on the deployment of GEH’s BWRX-300 small modular reactor in Sweden.

Holcomb

Indiana has joined the growing list of states looking into small modular reactors for future energy production as their coal-fired plants are retired.

Gov. Eric Holcomb on March 18 signed into law S. 271, which allows and incentivizes the construction of SMRs in Indiana. Introduced on January 10 and sponsored by state Sens. Eric Koch (R., Bedford) and Blake Doriot (R., Goshen), S. 271 passed in the Senate on February 1 in a 39–9 vote and in the House on February 22 by a vote of 70 to 22.

Specifics: S. 271 requires the Indiana Utility Regulatory Commission (IURC), in consultation with the state’s Department of Environmental Management, to adopt rules concerning the granting of certificates of public convenience for the construction, purchase, or lease of SMRs, defined as reactors with a rated electric generating capacity of not more than 350 MW. The rules are to be adopted by July 1, 2023.

Finnish utility Fortum Power and Heat Oy has submitted an application to Finland’s Ministry of Economic Affairs and Employment to operate the two reactors at the Loviisa nuclear power plant through 2050. The current operating licenses for Loviisa-1 and -2 expire in 2027 and 2030, respectively.

In a move motivated by Russia’s invasion of Ukraine and the sky-high energy prices hitting Europe as a result, the Belgian government last Friday announced its intention to extend the operational life of two of its nuclear power reactors, Doel-4 and Tihange-3, through 2035.

Europeans are taking resolute steps to reduce their output of climate-changing gases, but some countries are moving in the wrong direction.

Many countries are adding solar and wind, which are low-carbon energy sources. Some have moved to biomass, the value of which as a climate cure is not clear. A few are adding reactors, while others are defining nuclear as dirty energy and natural gas as “clean” and are changing their generation mix accordingly.

The State Nuclear Regulatory Inspectorate of Ukraine (SNRIU) informed the International Atomic Energy Agency yesterday that all safety systems at the Zaporizhzhia nuclear power plant in southeastern Ukraine were fully functional, one day after the site lost connection to a third external power line linking it to the national electricity grid.

A magnitude 7.3 earthquake struck off the east coast of Honshu, Japan, at 11:36 p.m. (local time) yesterday, resulting in significant ground shaking near the epicenter, much structural damage, at least four deaths, and a power outage affecting more than 2 million households, including some 700,000 in Tokyo. (According to Japanese utility Tepco, power was restored to all households by 2:52 a.m. on Thursday.)

An article posted on the Interesting Engineering website on March 10 highlights a recent YouTube video that provides an overview of the advantages, current status, future possibilities, and practical challenges of small modular reactors, along with a look at the even smaller microreactors. The video is available on the “Undecided with Matt Ferrell” channel. Ferrell describes himself as “a UI/UX [user interface/user experience] designer by trade” and “a lifelong tech enthusiast.”
