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 Department of Energy’s Office of Environmental Management (EM) has made great progress in accomplishing its cleanup of legacy radioactive waste but has yet to tackle its most challenging tasks, including the treatment of liquid tank waste at the Hanford, Idaho, and Savannah River sites. That was the consensus of the DOE-EM officials who took part in a panel session of the 2023 Waste Management Symposia, held February 26–March 2 in Phoenix, Ariz.

The development of human society and technology is closely correlated to the means of energy acquisition, utilization method, efficiency, and spectrum of applications. High quality of life and sustainable socioeconomic development require a sustainable and reliable energy supply. Wealth, health, food, water, infrastructure, education, and even life expectancy itself strongly correlate with the consumption of energy per capita. Having an adequate, reliable, affordable, eco-friendly, and sustainable supply of energy is becoming more crucial for economic development and improving human well-being.

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.”

While President Biden’s $6.9 trillion budget proposal for fiscal year 2024, submitted to Congress on March 9, was quickly pronounced “dead on arrival” by Sen. John Barrasso (R., Wyo.), it remains valuable as an indicator of the administration’s funding priorities for the coming year, including its nuclear energy priorities.

Which is why ANS on Wednesday hosted “An Inside Look at the FY 2024 Budget,” a members-only webinar moderated by ANS Executive Director/CEO Craig Piercy and featuring a team from the Department of Energy’s Office of Nuclear Energy, including DOE-NE head Kathryn Huff.

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.

According to a new study conducted by the economics consulting firm Analysis Group, “Massachusetts utilities could save their customers $880 million to more than $2 billion by 2032 by entering into a long-term power purchase contract with the Seabrook Station nuclear plant.” The study, Economic and Environmental Benefits to Massachusetts from the Operation of the Seabrook Nuclear Plant, also found that operation of the plant through 2032 is expected to contribute as much as $2.9 billion to the state’s economy and reduce regional greenhouse gas emissions by 5 million tons per year.

The rapid changes in the nuclear energy industry over the last decade, driven in part by fluctuating energy market prices and an aging fleet of reactors, have led to the closure of multiple reactors in the United States and other countries. These closures have increased the need for larger and more efficient ways to manage low-level radioactive waste processing and transport capacities. The safe transport of radioactive material is a key component of the overall nuclear industry reliability. Though sometimes perceived as a bottleneck and costly, it is necessary to send waste material to disposal.

The Nuclear Regulatory Commission has delayed issuing a decision on the licensing of Holtec International’s proposed consolidated interim storage facility (CISF) in New Mexico for at least two more months. In a letter sent to Holtec on March 20, the NRC said the delay was “due to unforeseen resource constraints.”

The International Atomic Energy Agency is inviting teens aged 14 to 18 to submit original comic book pages depicting a space-based nuclear science experiment on agricultural seeds that the agency is conducting with the United Nations’ Food and Agricultural Organization (FAO). The contest is offering prizes, including publication of the winning designs on the IAEA website, for the champion and finalists. The deadline for submissions is April 16.

Representatives of El Salvador’s government and the Thorium Energy Alliance have signed a memorandum of understanding to promote El Salvador’s plan for renewable energy through thorium.

The document was signed on March 14 by Daniel Alvarez, director general of energy, hydrocarbons, and mines, and John Kutsch, executive director of the Thorium Energy Alliance, at the El Salvador embassy in Washington, D.C. The signing was witnessed by Milena Mayorga, El Salvador’s ambassador to the United States.

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.

Progress continues on a new utility shaft at the Department of Energy’s Waste Isolation Pilot Plant in New Mexico as shaft-sinking crews recently surpassed the midway point at a depth of 1,076 feet. When complete, the full shaft depth will be 2,275 feet, with the team now halfway to the WIPP repository depth of 2,150 feet.

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.)

New Mexico has passed legislation aimed at preventing Holtec International from constructing and operating a consolidated interim storage facility (CISF) for spent nuclear fuel in the state. On March 17, hours after being passed by the New Mexico House on a 35-28 vote, Democratic Gov. Michelle Lujan Grisham signed SB 53, which prohibits the storage and disposal of radioactive waste in New Mexico without the state’s consent.

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.
