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.

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.

ANS leadership lays groundwork for new 10-year strategic plan

July 21, 2025, 3:00PMANS News

The last time the American Nuclear Society Board of Directors approved a strategic plan was back in 2018 under the direction of past president Bob Coward. Realizing a lot has changed with both ANS and the wider nuclear community, the current Board of Directors decided it was time to give our strategic plan a fresh look. Following the November 2024 ANS Conference, the Board has undertaken a comprehensive strategic planning process to align the Society’s direction with the realities of the rapidly changing energy and technology landscape.

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

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.

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.
