I am deeply honored and grateful to have been elected president of the American Nuclear Society. Your support and confidence in me are truly humbling, and I want to extend my heartfelt thanks to each and every one of you.

As president, my top priority is to expedite the deployment of new nuclear reactors, beginning with small modular reactors and eventually progressing to Generation IV systems. I will also work to ensure that the United States keeps its global leadership in this field. For the U.S. to do that, the federal government must maintain and expand its financial support of the nuclear industry by preserving critical incentives, tax provisions, and infrastructure investments.

Bahrain signs a nuclear collaboration MOU with the U.S.

July 22, 2025, 9:30AMNuclear News

Less than a week after news broke of the U.S. entering into civil nuclear talks with Malaysia, the U.S. State Department announced that Secretary of State Marco Rubio and Bahrain’s Minister of Foreign Affairs Abdullatif bin Rashid Al Zayani have also signed a memorandum of understanding concerning civil nuclear cooperation.

Test reactor fuel fabrication will be fast-tracked by DOE under new pilot program

July 21, 2025, 12:12PMNuclear News

The Department of Energy has announced a program to accelerate nuclear fuel fabrication for new test reactors. The Fuel Line Pilot Program would see the DOE approve facilities developed by U.S. companies to produce the fuel needed for test reactors the DOE expects to authorize under the Reactor Pilot Program announced in June. Like the reactors they’re meant to fuel, the fabrication facilities would be built on sites outside the DOE’s national laboratories but authorized by the DOE under “a fast-tracked approach to enable future commercial licensing activities for potential applicants.”

House Oversight Committee schedules hearing on nuclear energy

Burlison

Rep. Eric Burlison (R., Mo.), the chairman of the U.S. House Oversight and Accountability Subcommittee on Economic Growth, Energy Policy, and Regulatory Affairs, has announced a hearing on “The New Atomic Age: Advancing America’s Energy Future.”

The hearing will take place on Tuesday, July 22, at 1:00 pm (ET). Witnesses include Alex Epstein, president and founder of the Center for Industrial Progress, and Joshua Smith, energy policy lead at the Abundance Institute.

Details: According to the chairman’s office, the hearing will explore recent developments in nuclear energy technology, the commercial viability of advanced reactors, supply chain challenges, and policy pathways for Congress to strengthen nuclear power in the United States.

IAEA launches infographic design contest on nuclear preparedness and response

July 21, 2025, 7:03AMNuclear News

The International Atomic Energy Agency has launched an infographic design contest for young professionals aged 18 to 35 to raise awareness about emergency preparedness and response (EPR) in nuclear and radiological contexts.

The RAIN scale: A good intention that falls short

July 18, 2025, 3:28PMNuclear NewsAmir A. Bahadori

Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.

Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.

The Idaho National Laboratory has announced that it will collaborate with Microsoft on the use of artificial intelligence technologies to streamline the nuclear permitting and licensing application process. Using Microsoft’s Azure cloud computing platform, INL will generate the engineering and safety analysis reports that are required to be submitted for construction permits and operating licenses for nuclear power plants.

NRC confronts “unprecedented position”

July 17, 2025, 7:01AMNuclear News

The Nuclear Regulatory Commission, which currently has three serving commissioners and—according to recent media reports—a detailee from the Department of Government Efficiency (DOGE), is accelerating licensing timelines to meet the requirements of President Trump’s May 23 Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” and the ADVANCE Act. On top of that, the agency is preparing for an anticipated rush of applications while dealing with a reduced workforce.

Nuclear energy for maritime shipping and coastal applications

July 16, 2025, 3:01PMNuclear News

The Boston-based Deon Policy Institute has published a white paper that examines the applications of nuclear energy in the maritime sector—specifically, floating nuclear power plants and nuclear propulsion for commercial vessels. Topics covered include available technologies, preliminary cost estimates, and a status update on the regulatory framework.

Unique opportunity: The paper points out that nuclear energy has the potential to benefit the shipping industry with high energy efficiency, lower operating costs, and zero carbon emissions. The report has a special focus on Greece, a nation that controls about 20 percent of the global commercial fleet and thus has an opportunity to take a leading role in the transition to nuclear-powered shipping.

ANS seeks program evaluators for ABET accreditation

July 16, 2025, 12:00PMNuclear News

When ABET visits universities for accreditation purposes, it’s crucial that a qualified nuclear expert performs the assessment of that school’s nuclear engineering, radiological engineering, and/or health physics programs. The Accreditation Policies and Procedures Committee (APPC) of the American Nuclear Society works to ensure that a program evaluator (PEV) from the Society leads these ABET assessments.

For 2,300 hours, the molten salt pump Shaft Seal Test Facility (SSTF) operated at the University of Michigan’s Thermal Hydraulics Laboratory, according to an article from UM. The large-scale experiment was designed to evaluate shaft seal performance in high-temperature pump systems. Fewer than 10 facilities worldwide have successfully operated fluoride or chloride salts for more than 100 hours using over 10 kilograms of material.

Remembering ANS member Gil Brown

Brown

The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.

Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.

Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”

Researchers at the National Institute of Standards and Technology have developed a technique called cryogenic decay energy spectrometry capable of detecting single radioactive decay events from tiny material samples and simultaneously identifying the atoms involved. In time, the technology could replace characterization tasks that have taken months and could support rapid, accurate radiopharmaceutical development and used nuclear fuel recycling, according to an article published on July 8 by NIST.
