Russian shelling is being blamed for damage to the single remaining power source to Ukraine’s Zaporizhzhia nuclear power plant, located on the front lines of the ongoing military conflict.

“After another attack by the Russians, the line that provided the energy supply to the Zaporizhzhia nuclear station was damaged,” Ukraine's power grid operator Ukrenergo said in a February 21 statement.

As hydrogen production increases worldwide, some see clean hydrogen as a game-changer when it comes to decarbonizing the steel industry.

Steel production is one of the “hard-to-abate” sectors of industry, which are responsible for about 30 percent of global carbon emissions. These industries are tough to decarbonize because the technologies either do not yet exist or are considered uneconomical.

A ceremonial ground-breaking event took place last week at the site where the Atomic Energy Organization of Iran (AEOI) says four new nuclear reactors will be built over the next 20 years.

Recent staff cuts at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP) are raising concerns among international nuclear watchdogs.

Ahead of his visit to the plant on February 7, International Atomic Energy Agency director general Rafael Mariano Grossi told the Associated Press that he will focus on the impact of personnel reductions, especially while Russia has denied access to employees of Ukraine’s nuclear operator, Energoatom.

The Advanced Reactor Codes and Standards Collaborative (ARCSC) held its second workshop on November 30, 2023, in Washington, D.C. The hybrid event had just over 200 participants, including representatives from standards development organizations (SDOs), the Electric Power Research Institute, the Nuclear Energy Institute, national laboratories, government agencies, vendors, advanced reactor designers, and consultants. Also in attendance were representatives from other U.S. industry and international organizations, including the International Atomic Energy Agency. ANS Standards Board chair Andrew Sowder, senior technical executive at EPRI, welcomed attendees to EPRI’s offices, where the workshop was held.

More people in low- and middle-income countries who have head and neck cancer may be able to access lifesaving radiotherapy after research supported by the International Atomic Energy Agency has shown that fewer—but higher—doses of radiation treatment resulted in clinical outcomes similar to standard radiotherapy treatments. Reducing overall treatment times for this type of cancer through a treatment regimen called hypofractionation could help countries navigate resource constraints and shorten waitlists, enabling more patients to receive treatment while also reducing the cost and duration of care. The IAEA announced the findings in a news article published January 22.

The International Atomic Energy Agency, in cooperation with Argentina, launched a scientific research expedition on January 6 to study microplastics in Antarctica—one of the planet’s most remote areas—as part of an effort to combat widespread microplastic pollution.

Ukraine’s Zaporizhzhia nuclear power plant has taken action to ensure an immediate supply of backup electricity at the site in case the main external power line is lost.

Amid Ukraine's ongoing military conflict with Russia, Zaporizhzhia has experienced frequent power cuts. Since August 2022, the plant has suffered eight events with a complete loss of off-site power, according to a statement from International Atomic Energy Agency director general Rafael Mariano Grossi.

Recent observations have indicated that warm water has been discharged near the light water reactor at the Yongbyon Nuclear Scientific Research Center in North Korea, which is consistent with the purported commissioning of the LWR—a process that takes time for any new reactor—and suggests that the reactor has now reached criticality.

“The LWR, like any nuclear reactor, can produce plutonium in its irradiated fuel, which can be separated during reprocessing, so this is cause for concern,” said Rafael Mariano Grossi, director general of the International Atomic Energy Agency. “It remains the case that without access to the facility, the agency cannot confirm its operational status.”

Safety concern: Grossi went on to say that the agency does not have sufficient information to make an assessment about the Democratic People’s Republic of Korea site, but that nuclear safety remains the paramount issue when starting a new reactor. Agency inspectors have had no access to North Korea since they were expelled in 2009.

A series of earthquakes on New Year’s Day that resulted in a tsunami warning and prompted evacuations from Japan’s west coast caused no irregularities at the country’s nuclear plants, Japanese officials have reported.

The International Atomic Energy Agency completed an advisory service mission to Cambodia on December 11–22 that focused on assessing the country's security regime for nuclear and other radioactive material out of regulatory control (MORC).

Seventy years ago to the day, President Dwight D. Eisenhower gave his historic address to the United Nations General Assembly in New York City. (See December 2023 Nuclear News's “Leaders” column to read the reflections of Kathryn Huff, the Department of Energy’s assistant secretary for nuclear energy, on the speech’s anniversary.)

President Dwight D. Eisenhower delivered his “Atoms for Peace” speech to the United Nations General Assembly in December 1953. In this historic address, he invoked the existential threat of nuclear weapons proliferation and the potential horror of nuclear war to muster the diplomatic energy of the United Nations toward establishing peaceful uses for the atom. The speech launched domestic and international initiatives, including the International Atomic Energy Agency, that would underpin decades of robust, peaceful nuclear power commercialization and expansion.

This month, as we celebrate the 70th anniversary of that speech, we celebrate Eisenhower’s prescience in suggesting that “experts would be mobilized to apply atomic energy to the needs of agriculture, medicine, and other peaceful activities” and “to provide abundant electrical energy in the power-starved areas of the world.” Mobilizing American experts, of course, would mean refocusing the work of the national laboratories toward peaceful uses of the atom and repurposing the vast weapons complex investments of the 1940s toward more peaceful ends.

This spring, Waste Management Symposia will celebrate its 50th anniversary when the conference convenes in Phoenix, Ariz., on March 10–14, 2024. Since the first international conference in 1974, WMS has grown to nearly 3,000 attendees representing more than 30 countries. The conference is an open forum for the exchange of information and discussion of opportunities related to all aspects of radioactive waste and materials management. As a nonprofit organization, all proceeds from the WMS conference go toward providing education and information on global radioactive waste management.

As countries increasingly plan to adopt or expand nuclear energy to their energy grids, the importance of national and international nuclear law was underscored in recent remarks by Rafael Mariano Grossi, the International Atomic Energy Agency’s director general.

Blaming “the criminal actions of the ruscists,” Ukraine nuclear plant operator Energoatom this morning reported a primary-to-secondary reagent leak at Unit 5 of the Russian-occupied Zaporizhzhia nuclear power plant (ZNPP), as well as a partial blackout at the facility earlier this week. (The term “ruscist” [рашизм] is a portmanteau of the words “Russian” and “fascist.”)

A team of experts from the International Atomic Energy Agency recently concluded an eight-day mission to Estonia, finding that the Baltic state has developed a comprehensive assessment of its nuclear infrastructure development needs, enabling the government to make an informed decision on whether to pursue a nuclear power program.

There has been a lot of breathless coverage surrounding the release of mildly tritiated wastewater from the Fukushima Daiichi site, generated in no small part by people, organizations, and even nations with a political axe to grind. But here are the facts:

On August 24, 2023, Fukushima Daiichi began its first release of tritium-containing water, following the Japanese government’s plans to meet all international guidelines. The International Atomic Energy Agency, which has established a permanent office at the plant, provided on-site observation, online monitoring, and an independent analysis of the release. (The IAEA will continue to do so for all future releases.) Tokyo Electric Power Company (TEPCO) reported that analyses of water samples taken from the sea within three kilometers of the plant showed tritium concentrations below 10 becquerels per liter, well below the 700 becquerels per liter set by the utility for suspending the release, and substantially below the drinking water quality standard of 10,000 becquerels per liter set by the World Health Organization.

Explosions near the Khmelnytskyi nuclear power plant in western Ukraine early Wednesday shattered windows at the facility and temporarily cut off power to some off-site radiation monitoring stations, the International Atomic Energy Agency reported on October 25.
