Popular Mechanics takes the wind out of renewables study

Hurricanes, wildfires, and other disasters across the United States caused $95 billion in damage last year, according to new data referenced by the New York Times. The cost is almost double the amount in 2019 and the third-highest loss since 2010.

The new figures, reported January 7 by Munich Re—a company that provides insurance to other insurance companies—are the latest signal of the growing cost of climate change. The spike reflects the need for increased reliance on clean energy sources such as nuclear, solar, and wind.

Just released by a group called 18 for 0, the 47-page preliminary study Nuclear Development in Ireland makes the case for bringing nuclear energy to the Emerald Isle.

Electricity generation from nuclear fission is prohibited by Ireland’s Electricity Regulation Act of 1999.

In another sign of U.S. interest in helping Poland develop a civil nuclear power program, the Export-Import Bank of the United States announced last week that it has signed a memorandum of understanding with the Polish government to promote U.S. energy investment in the Central European nation. (For an earlier agreement, see here.)

The MOU was signed in Warsaw on December 11 by Ex-Im president and chairman, Kimberly A. Reed, and Poland’s minister of climate and environment, Michał Kurtyka, during Reed’s three-day visit to Poland.

The Ex-Im: As the official export credit agency of the United States, Ex-Im provides loans, loan guarantees, and insurance to foreign customers purchasing U.S. exports.

The MOU particulars: The MOU calls for Ex-Im and Poland to “explore and identify potential opportunities for Ex-Im financing and to work together to promote business development opportunities related to strategic energy projects and programs,” according to Ex-Im’s announcement. The agreement includes, but is not limited to, support for projects in nuclear energy, in particular in support of strategic projects under Poland’s nuclear power program, low- and zero-emission technologies, clean energy innovation, and critical energy infrastructure, including cybersecurity solutions.

The January/February 2021 issue of Popular Mechanics hit subscriber mailboxes this week with a stark cover image of a single small reactor under the headline, “Tiny nuclear reactors are about to revolutionize American energy.” The story looks at advanced reactors as a pivotal step to “redeem nuclear’s stature in American energy.”

A good primer: The article does a good job introducing the casual reader to the idea that “bigger is no longer better” and that the future of nuclear power in the United States will most likely be “a combination of traditional large plants and smaller, safer megawatt reactors.”

Advanced reactors, including small modular reactors, show that nuclear is no longer a one-size-fits-all operation, the article notes. The industry now “is all about personalization,” says Ken Canavan, Westinghouse’s chief technical officer, who is quoted in the article. The capacity and scalability of SMRs “is just irreplaceable,” he adds.

The article explains that SMRs, microreactors, and other advanced reactor designs will be able to bring reliable, carbon-free power to small or remote locations, replacing fossil fuel power plants and supplementing the “resource-sucking downtimes left by renewables.”

A 170-page energy white paper, Powering Our Net Zero Future, issued by the United Kingdom government on December 14 sets big goals for cleaning up the U.K.’s energy system. According to the U.K. government, the plan would create and support green energy jobs across England, Scotland, Wales and Northern Ireland and would keep electricity bills affordable as the U.K. transitions to net zero emissions by 2050.

The white paper notes that the U.K. will generate emission-free electricity by 2050 with a trajectory that will see "overwhelmingly decarbonized power in the 2030s. Low carbon electricity will be a key enabler of our transition to a net zero economy with demand expected to double due to transport and low carbon heat."

The white paper builds upon the U.K. prime minister’s 38-page Ten Point Plan for a Green Industrial Revolution, which was issued on November 18.

The U.S. Congress has failed to uphold its promise to fully fund Yucca Mountain, in Nevada, as a permanent repository for spent nuclear fuel, Rep. Michael C. Burgess (R., Texas) writes in an op-ed article published on December 8 in the Dallas Morning News.

More than three decades after passing the Nuclear Waste Policy Act, Congress has yet to fully fund the Yucca Mountain Project. Burgess points out that while some countries have found success with reprocessing spent fuels, the fission process will always produce some amount of material that must be safely disposed, making it necessary to find a permanent solution.

The Santa Fe New Mexican, in its October 24 edition, reported on a study by the University of New Mexico’s Bureau of Business and Economic Research that found that the state could use money from a nearly $1- billion federal mining settlement to create a new industry around the cleanup of abandoned uranium mines in the Southwest.

“The world needs a mix of renewable power sources, including one that can carry on producing power when the others can’t—the sun doesn’t always shine and the wind doesn’t always blow,” British journalist Jonathan Gornall writes in an opinion piece posted Wednesday on the Asia Times website. Gornall argues that the residents of Suffolk County in the United Kingdom would be better served by the expansion of the Sizewell nuclear power plant than by leaving a wooded area untouched.

Responding to a paper published in Nature Energy, the Nuclear Innovation Alliance (NIA) wrote in an October blog post that nuclear is a carbon-free energy source with an important role to play in decarbonizing the global economy.

High-energy radiation can be detrimental to electronic equipment, necessitating the use of radiation-hardened and -resistant electronics in nuclear energy, decommissioning, and space exploration. The online newsletter Tech Xplore reports on a radiation-hardened and repairable integrated circuit being fabricated by researchers at Peking University, Shanghai Tech University, and the Chinese Academy of Sciences.

The radiation-immune and repairable circuits developed by the researchers are based on field-effect transistors (FET) that use a semiconducting carbon nanotube transistor as a channel, an ion gel as its gate, and a substrate made of polyimide. According to the article, the FETs have a radiation tolerance of up to 15 Mrad, which is notably higher than the 1 Mrad tolerance of silicon-based transistors. The FETs are also capable of being recovered by annealing at moderate temperatures (100 °C for 10 minutes).
