A recurring leak of water containing tritium has led to the temporary shutdown of Xcel Energy's Monticello nuclear power plant, in Minnesota.

“While the leak continues to pose no risk to the public or the environment, we determined the best course of action is to power down the plant and perform the permanent repairs immediately,” said Chris Clark, president of Xcel Energy–Minnesota, North Dakota, and South Dakota, in a March 23 news release. “We are continuing to work with and inform our state, federal, city, and county leaders in the process.”

Powering down the reactor to shutdown condition started last Friday.

The University of Missouri intends to build a new, larger research reactor to produce medical radioisotopes, announcing that it intends to issue a request for qualification/request for proposal (RFQ/RFP) in April to solicit interest from qualified parties to provide preliminary designs and industry partnerships for the new reactor project, called NextGen MURR.

The White House’s recently released budget request for fiscal year 2024 would provide $1.006 billion in gross budget authority for the Nuclear Regulatory Commission—an increase of $63.2 million, or about 6.7 percent, from the enacted FY 2023 level. According to the agency, the boost is largely for increased salaries and benefits “consistent with the Office of Management and Budget guidance.”

The Nuclear Regulatory Commission will hold four hybrid meetings around the United States as it seeks comment on a proposed rule to update its license renewal generic environmental impact statement (GEIS).

“I’m glad you came to our party!” said GE Hitachi Nuclear Energy (GEH) chief nuclear officer Nicole Holmes as she prepared to announce that Wilmington, N.C.–based GEH will develop a standard design for its BWRX-300 boiling water small modular reactor with not one but three power producers representing three countries: Tennessee Valley Authority (TVA), Ontario Power Generation (OPG), and Synthos Green Energy (SGE). Celebration was a theme throughout the March 23 event held in Washington, D.C., which was flush with dignitaries representing the United States, Canada, and Poland.

Most people probably don’t think about nuclear power in terms of religion, but the association may not be so far-fetched, as suggested by a resolution adopted by the 185th Convention of the Episcopal Diocese of Chicago. “Supporting a Clean Energy Future” was passed on November 19, 2022, with 78 percent of participants voting affirmatively.

The Department of Energy’s Oak Ridge National Laboratory (ORNL) and the U.K. Atomic Energy Authority (UKAEA) have formed a strategic research partnership to investigate how different types of materials behave under the influence of high-energy neutron sources. The five-year partnership was announced by ORNL and by the UKAEA on March 13.

An Xcel Energy news release issued last week regarding the leak of some 400,000 gallons of tritium-containing water at Minnesota’s Monticello nuclear power plant in 2022 has sparked a flood of news stories over the past few days—in large part because the general public had previously been unaware of the leak. (A low-level beta emitter, tritium is a common byproduct of nuclear reactor operation.)

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.

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.”

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.

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.

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.

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.”

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.

“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.”

Proponents of Diablo Canyon nuclear power plant received the heartening news on March 2 that the Nuclear Regulatory Commission had granted a “timely renewal” exemption to allow the plant to continue operating while its new license renewal application was under review. The exemption came after the NRC denied in January plant owner Pacific Gas & Electric’s request for the agency to resume review of its original license renewal application.

X-energy, the Rockville, Md.–based small modular reactor developer, has announced its plan to open the first Xe-100 reactor fleet management, monitoring, and training facility—the Plant Support Center–East (PCSE)—in the fourth quarter of this year.

A nuclear-powered hydrogen production facility has commenced operation at Constellation Energy’s Nine Mile Point plant, the company announced this week. The facility is the first of its kind in the United States to generate hydrogen using nuclear power, courtesy of the New York plant’s two boiling water reactors, the 620-MWe Unit 1 and 1,287-MWe Unit 2.
