Grouting Hanford’s low-level radioactive liquid tank waste could cost between $480 million and $1.1 billion, according to a report by the Government Accountability Office, which has repeatedly found that grouting (immobilizing waste in a concrete-like mixture) can accelerate cleanup at the Hanford Site and save billions of dollars when compared to mixing the waste with molten glass through the vitrification process.

The dormant Blue Castle nuclear power plant project in Utah has resurfaced, only this time as a proposed small modular reactor facility.

Blue Castle Holdings and Fulcrum Point Holdings—founded by the owner of Hi Tech Solutions, a company behind a separate Utah nuclear project—announced last week a joint venture to advance the Blue Castle project in Green River, Utah, the origins of which trace back almost 20 years.

The ITER Organization has announced that its magnet cold test facility is now in operational mode, allowing the preinstallation testing of superconducting magnets at the fusion reactor’s low operating temperature of 4 Kelvin (−269°C; −452°F) and full current of 68 kiloampere (kA).

Today, there are 34 countries with operational nuclear power plants—but there are dozens more working on building a nuclear plant of their own. While progress on these projects inevitably ebbs and flows, broadly, momentum seems to be building on the international stage.

That growing momentum manifested last week in Kazakhstan’s announcement that it has officially partnered with Russia on a new nuclear power plant project. Prior to these new agreements, Russia, which borders Kazakhstan to the north, was already engaged in extensive preliminary work on the project.

In 2019, a familiar landmark at Idaho National Laboratory was scheduled for demolition. Though striking for both its physical presence and its significance to nuclear history, the containment dome that once housed Experimental Breeder Reactor-II sat unused—that is, until INL realized its potential as a reactor testing facility.

A team of scientists from Lawrence Livermore National Laboratory has observed, imaged, and characterized the early stages of hydrogen-uranium corrosion for the first time, the lab announced recently.

Washington, D.C.-based Curio announced yesterday that it has submitted a letter of intent to the Nuclear Regulatory Commission to establish a docket for preapplication engagement activities and ultimately the submittal and review of a license application to operate a spent nuclear fuel recycling production facility.

Once a docket is established, Curio will develop a license application to meet all applicable regulations for a nuclear fuel recycling facility under 10 CFR Part 70.

Nuclear officials in Kenya want to engage with residents in Siaya County and keep them informed as the country moves toward building its first nuclear power plant.

The state-run Nuclear Power and Energy Agency said on May 23 it will conduct a “robust, transparent, and multilayered educational campaign to address all anxieties regarding safety, livelihoods, and land,” and that no infrastructure would be built without “broad, informed consent of the community.”

Studies, regulatory control, and legislation are among the items Nebraska, Minnesota, Indiana, and North Carolina tackled in the month of May regarding nuclear energy.

Nuclear start-ups Oklo and Flibe Energy both announced this week that they have been selected by the Department of Energy for advanced negotiations under the department’s Surplus Plutonium Utilization Program, which aims to make surplus U.S. plutonium available to the nuclear industry for advanced reactor fuels.

According to multiple reports, three other companies—Exodys Energy, Shine Technologies, and Standard Nuclear—have also been selected for advanced negotiations under the program, which is being led by the DOE’s Office of Nuclear Energy.

Ahead of this year's Annual Conference, which is taking May 31–June 3 in Denver, Colo., the American Nuclear Society is excited to recognize exceptional individuals in the nuclear community. This season’s national award recipients and new Fellows of ANS will receive official recognition during the opening plenary on Monday, June 1.

Later this year, the U.S. Navy will test the power-generating capabilities of one of its crown jewels, the nuclear-powered USS Gerald R. Ford—aiming to demonstrate its ability to provide electricity to installations on shore.

Before the Fukushima Daiichi accident in March 2011, nuclear power from 54 reactors provided about 30 percent of Japan’s electricity. In the wake of the disaster, Japan shut down every one of its reactors.

Recently, the country has been restarting its nuclear power plants. Among its current fleet of 33 operable reactors, fewer than half have been restarted. Nuclear power is currently providing about 8.5 percent of Japan’s electricity (with natural gas and coal accounting for more than 60 percent).

The Japanese government’s present energy plan, announced last year, calls for nuclear power to meet 20 percent of the country’s electricity needs by 2040. While the government views nuclear as a crucial asset toward meeting its goal of net zero emissions by 2050, public support for nuclear energy also continues to increase. A 2012 Pew Research poll—conducted one year after the Fukushima Daiichi disaster—indicated that 70 percent of the public opposed nuclear power. However, a 2022 poll by Nikkei Business Publications suggests that now, more than 50 percent of the public supports nuclear power—if safety can be ensured.

Contributing their expertise to these restarts in recent years are young nuclear industry professionals who were trained a decade ago in a mentorship/training program involving U.S. institutions.

This “Super Engineer Project” was sponsored by Japan’s Ministry of Economy, Trade, and Industry and Hokkaido University from 2015 to 2017. METI sponsored the project to improve the Japanese nuclear safety culture by learning from the U.S. safety culture.

Researchers from the University of Michigan and Oak Ridge National Laboratory have found that predictions of helium generation rates through neutron transmutation in fission and fusion reactors vary widely and include dependencies on the choice of nuclear data library and calculation method.

The Nuclear Regulatory Commission said it intends to complete its review of Orano Enrichment’s license application to build and operate a new uranium enrichment facility near Oak Ridge, Tenn., in 12 months. Orano submitted its application for the multibillion-dollar facility, named Project Ike, in March.

SMR-300 deployments, power plant names, trade missions, agreements between neighboring countries, and renewed interest in nuclear energy are among the notable developments that occurred internationally in the month of May.

On Tuesday, the National Reactor Innovation Center hosted an industry day for the Nuclear Energy Launch Pad, providing a forum for companies to learn more about how the program works, timelines, collaboration with the various entities involved, and available resources.

The launch pad is a long-term program stemming from the Reactor Pilot Program and Fuel Line Pilot Program. It aims to fast-track regulatory processes for new reactors and fuel facilities that meet certain milestones.

This Saturday, May 23, will mark one year since President Trump issued four executive orders (EOs) that sought to implement sweeping changes across the U.S. nuclear industry. From regulatory reform at the Nuclear Regulatory Commission to new authorization projects at the Departments of Energy and Defense, the orders sent ripples throughout the industry.

A report by the Government Accountability Office has shown that the Department of Energy’s Office of Environmental Management continues to face significant staffing shortages since the GAO first reported on the problem in 2024. This includes a shortage in workers considered critical to carrying out the office’s mission of cleaning up radioactive waste from decades of nuclear weapons production and research.

A collaboration between the Department of Energy’s Office of Isotope R&D and Production and the Department of Commerce’s National Institute of Standards and Technology has recovered large quantities of radium-226—valued for its use in medical radioisotope production—from radiological waste stored at NIST facilities. Ra-226 is an important element in developing therapies for patients fighting cancer.
