This year marks the 25th year that ANS's Nuclear News magazine has published its Reference Section, which features a world list of nuclear power plants, maps showing worldwide plant locations, tables with information on U.S. plant renewals, and international data tables and graphics. What follows are interesting tidbits that Nuclear Newswire has picked up from this year's Reference Section, which was published in the March NN.

From the Reference Section
Five power reactors started commercial operations around the world in 2022 and five more closed, leaving the total number of operable nuclear power reactors in this 25th Annual Reference Section at 434, the same as the year before. What’s more, that number is just one more than the 433 power reactors listed in the 1st Annual Reference Section back in 1999. But make no mistake, plenty has changed over 25 years. Read on.

Attracting more than 2,000 attendees, the 2023 Waste Management Symposia was held February 26–March 2 in Phoenix, Ariz. For many, this year’s conference was a return to business as usual, with a packed exhibit hall and well-attended technical session, as the upheaval brought about by the pandemic that began three years earlier seemed a thing of the pasts. Not that those who gathered in Phoenix threw any caution to the unseasonably cold and rainy winds that descended across Arizona this year.

Despite nuclear power producing 10 percent of energy globally, it seems sometimes that ours is a world in which nuclear does not exist. We all have our own lives, our own passions, and our own separate interests—each of which in turn can feel like a world of its own. For example, I competitively water ski, and rarely does nuclear engineering come up during water skiing tournaments. Nuclear science is a major part of my life and my world—but it is not the only piece. Many of my other worlds have no intersection with nuclear science.

One of my worlds is my involvement in the Miss America Organization. I previously have shared stories about my experience as Miss Wisconsin, including using my platform to talk about nuclear with various individuals. Part of this role was competing for Miss America 2023, a title and position I was honored to win on December 15, 2022.

Hunt

In his spring 2023 budget speech to the House of Commons last Wednesday, U.K. chancellor of the exchequer Jeremy Hunt confirmed that, subject to consultation, nuclear power will be classified as environmentally sustainable in the U.K. green taxonomy, providing potential private investors in nuclear projects access to the same incentives currently enjoyed by investors in renewables. (Last year, the European Union added nuclear and natural gas to the list of green technologies covered by its taxonomy, but only on a transitional basis under what the European Commission termed “clear and strict conditions.”)

“We have increased the proportion of electricity generated from renewables from under 10 percent to nearly 40 percent,” Hunt declared. “But because the wind doesn’t always blow and the sun doesn’t always shine, we will need another critical source of cheap and reliable energy. And that is nuclear.”

Following a second planned maintenance outage, the Tank-Side Cesium Removal (TSCR) system at the Hanford Site in Washington state has resumed processing liquid tank waste, the Department of Energy’s Office of Environmental Management (EM) announced on March 14.

According to EM, its Office of River Protection (ORP) and contractor Washington River Protection Solutions processed more than 25,000 gallons of waste during the previous week and has treated a total of 406,000 gallons of radioactive liquid waste since TSCR began operations early last year.

A key component in Hanford’s Direct-Feed Low-Activity Waste program for treating tank waste, TSCR removes radioactive cesium and solids from tank waste and delivers low-activity waste to a nearby million-gallon tank, where it is staged until it can be fed to the Waste Treatment and Immobilization Plant for vitrification.

Outage improvements: During outages, workers change out filter columns that remove radioactive solids during waste processing, perform maintenance, and apply lessons learned from operations. According to EM, many improvements to the treatment system during outages over the past year came from recommendations made by workers and contractor and federal staff on the project team.

The African continent is made up of 54 countries and can be broadly divided into North Africa and Sub-Saharan Africa. For global power, Africa is an emerging frontier that holds much promise and could potentially be a new sphere of influence. It has a larger land mass than India, China, the contiguous United States, and Eastern Europe combined, but it can be easy for those unfamiliar with the continent to underestimate its size, influence, and diversity. In the coming years, Africa will play a growing role in global economics and demographics.

Tsai

The antinuclear energy policies of Taiwanese president Ing-wen Tsai, of Taiwan’s republic’s Democratic Progressive Party, stoked controversy on March 14 when the nation’s Kuosheng-2 nuclear power plant was taken off line to be decommissioned. Minister of economic affairs Mei-hua Wang, who oversees the state-run Taiwan Power Company (Taipower), claimed that the shutdown will not affect power supply because it will be offset by hydroelectric power, as well as gas- and coal-fired power plants. However, objectors to the shutdown claim the possibility of electricity blackouts, with opposition legislator I-ding Wu, of the Kuomintang (Chinese Nationalist) Party, countering that renewable energy would be insufficient to meet Taiwan’s energy needs and that fossil fuels are “dirtier” and “more expensive.”

Nuclear-free homeland: Tsai came to office in 2016, promising to make Taiwan a “nuclear-free homeland” by 2025 by decommissioning all six of its operable nuclear reactors when their 40-year operating licenses expired.

Further building on their already secure reputations as nuclear energy supporters, Sens. Joe Manchin (D., W.Va.) and Jim Risch (R., Idaho) yesterday reintroduced the International Nuclear Energy Act (INEA). (The lawmakers are also cosponsors of two recently debuted nuclear-themed bills: February’s Nuclear Fuel Security Act and last week’s Reduce Russian Uranium Imports Act.)

Westinghouse Electric Company announced on March 14 that the Nuclear Regulatory Commission has approved the use of the company’s Advanced Doped Pellet Technology (ADOPT) fuel pellets in U.S. pressurized water reactors. That approval brings the company closer to loading lead test assemblies containing ADOPT accident tolerant fuel pellets in Unit 2 of Southern Nuclear’s Vogtle plant.

GE Hitachi Nuclear Energy’s (GEH’s) BWRX-300 technology has completed phases 1 and 2 of the Canadian Nuclear Safety Commission’s vendor design review (VDR) process, the Wilmington, N.C.–based company announced yesterday.

Hosted by Waste Management Symposia, the annual Waste Management Conference is widely regarded as the premier international conference on the management of radioactive material and related topics. The theme of this year’s conference, being held February 26-March 3 at the Phoenix Convention Center in Arizona, is “Planning for the Future: Innovation, Transformation, Sustainability.” The featured country for 2023 is France, which will be represented by numerous panels, papers, posters, and exhibits demonstrating the country’s continuous innovation and pragmatism in the management of the nuclear fuel cycle. The featured Department of Energy Office of Environmental Management topic is “EM’s Transformation in Radioactive Liquid Tank Waste Management.”

Each year, the two best oral presentations/papers from the previous year’s conference are recognized. Honoring the highest-quality presentations, the American Nuclear Society and the American Society of Mechanical Engineers each present an award for best presentation/paper. The following are the abstracts for the best ANS and ASME papers of 2022. The full papers are available to 2023 WM Conference participants through the WM Symposia website, at wmsym.org.

EDF Energy, owner and operator of the United Kingdom’s nuclear reactor fleet, announced last week that it intends to keep its Hartlepool and Heysham 1 stations in operation to March 2026—two years past their previously scheduled 2024 retirement dates. EDF added that an additional 12 months of operation beyond 2026 is being contemplated.

For those who missed the recent Conference on Nuclear Training and Education: A Biennial International Forum (CONTE 2023), which was held on February 6–9 in Amelia Island, Fla., ANS hosted on March 9 an online panel discussion recapping selected highlights. The conference had the theme of “Maintaining Excellence Today—Building the Nuclear Workforce for Tomorrow!”

Four panelists summarized their CONTE presentations in the online discussion: Annaliese Piraino, instructional technologist at Energy Harbor’s Beaver Valley nuclear power plant; Sterling Parmenter, senior maintenance and technical instructor at Constellation Energy’s Nine Mile Point nuclear power plant; Lori Brady, senior director of human resources and training and development at the Nuclear Energy Institute; and David Helling, senior training advisor at Westinghouse Electric Company. The online event was moderated by Billy Wilson, senior engineer in nuclear training at Ontario Power Generation.

The Women in Nuclear chapter at Entergy Nuclear has been recognized by the U.S. WIN organization as the “most reactive” for its educational outreach efforts conducted during last year’s Nuclear Science Week.

The annual award recognizes significant achievements in promoting nuclear science in the community. U.S. WIN chapters are judged on the number of activities held during Nuclear Science Week, the number of participating WIN members, the number of individuals and public sectors reached, and the variety of topics covered.

Manchin

Barrasso

A bipartisan group in the Senate is making another attempt to ban Russian uranium with the introduction of S. 763, the Reduce Russian Uranium Imports Act, after similar legislation introduced in the previous Congress just under one year ago by Sen. John Barrasso (R., Wyo.) failed to advance.

Debuting March 9, the new bill is sponsored by Barrasso and Sens. Joe Manchin (D., W.Va.), Jim Risch (R., Idaho), Martin Heinrich (D., N.M.), Cynthia Lummis (R., Wyo.), Chris Coons (D., Del.), and Roger Marshall (R., Kan.). Specifically, S. 763 calls for prohibiting “the importation into the United States of unirradiated low-enriched uranium that is produced in the Russian Federation or by a Russian entity.”

“Nuclear is finding its way into real acceptance and enthusiasm, and that’s really exciting.” So said secretary of energy Jennifer Granholm at the COP27 climate conference last November.

For the past 65 years, humanity has harnessed the power of the atom. Since the grid connection of the world’s first commercial nuclear plant in 1957, nuclear has been an unsung hero in providing reliable, clean energy for generations. Nuclear is the world’s fourth-largest source of energy and the second-largest low-carbon source of energy, per Our World in Data.

And yet, it wasn’t until September of 2021, when it became increasingly clear that the world was entering an energy crisis, that nuclear found its way back into the spotlight. Five months later, with the invasion of Ukraine, countries dependent on Russian gas found themselves in a precarious and costly position.

Nuclear dismantling and decommissioning company APTIM said it is on schedule to wrap up field activities decommissioning the U.S. Navy’s Surface Ship Support Barge (SSSB) by April, with project closure slated for June. The company announced yesterday that its team has completed the demolition of the barge’s former spent fuel water pool, also referred to as the “wet pit,” or the heart of the vessel.

NuScale Power, the Portland, Ore.–based small modular reactor developer, announced last week that it has placed the first upper reactor pressure vessel (RPV) long-lead material (LLM) production order with South Korea’s Doosan Enerbility.

The Nuclear Regulatory Commission has authorized the restart of a test reactor at the National Institute of Standards and Technology, in Gaithersburg, Md. The reactor was shut down in February 2021 when a fuel element became damaged during startup and approach to full power. The incident violated the NRC’s fuel cladding temperature safety limit, although public health and safety were not affected, according to the agency.

The reactor is located at NIST’s Center for Neutron Research.

“Right now, our country is deficient in nearly every aspect of the fuel cycle. This must change and it must change quickly,” said Sen. Joe Manchin (D., W.V.), chairman of the Senate Committee on Energy and Natural Resources (ENR), as he opened a Full Committee Hearing to Examine the Nuclear Fuel Cycle on March 9. “Whether it is uranium mining, milling, conversion, enrichment, nuclear fuel fabrication, power generation, or nuclear waste storage and disposal, there is much work to be done, starting with conversion and enrichment. Simply put, Russia dominates the global market, representing nearly half of the international capacity for both processes.”
