Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

The fabrication of gloveboxes is underway for the plutonium pit production mission at the Department of Energy's Savannah River Site near Aiken, S.C.

“Gloveboxes will be a key component of pit production operations within the Savannah River Plutonium Processing Facility [SRPPF],” said Dennis Carr, president and CEO of Savannah River Nuclear Solutions (SRNS), the management and operating contractor for the site. “The early procurement and fabrication of these gloveboxes is critical to delivering completion of this project for the National Nuclear Security Administration by the early 2030s.”

The International Atomic Energy Agency team at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP) reported hearing gunfire near the site this morning while a drone hit the plant’s training center.

In a news release today, IAEA director general Rafael Mariano Grossi said this is the third drone to target the training center, located just outside the site perimeter, so far this year. He called for an immediate end to drones being flown over or near nuclear facilities.

The National Nuclear Security Administration announced that it will prepare a programmatic environmental impact statement (PEIS) to ensure National Environmental Policy Act compliance for the administration’s production of plutonium pits. The NNSA is inviting the public to participate in the PEIS process and to comment on the scope, environmental issues, and alternatives for consideration in drafting the document.

The Defense Innovation Unit announced April 10 next steps in the Advanced Nuclear Power for Installations (ANPI) program, launched in 2024 to deploy microreactor nuclear systems for increased power reliability at select military locations.

Brandon Williams appeared before the U.S. Senate’s Committee on Armed Services this week to answer questions on how he would lead the Department of Energy’s National Nuclear Security Administration, if confirmed for the job.

President Donald Trump announced Williams as his pick for the NNSA role in January. Energy Secretary Chris Wright said he was personally involved in the selection of Williams for the role, telling the Exchange Monitor in January, “He’s a smart, passionate guy [who] wants to defend our country.”

The Korea Times has reported that a Department of Energy contract employee at Idaho National Laboratory has been terminated for trying to take INL-owned, export-controlled, proprietary nuclear reactor design software on a flight to South Korea. The individual was stopped while attempting to board a Korea-bound flight with the design software, according to a formal report that the DOE Office of the Inspector General submitted to Congress for the period October 2023–March 2024.

Ukraine’s State Emergency Service has finally gained full control over a blaze that started February 14 after a drone struck the protective dome over the destroyed reactor from the 1986 Chernobyl nuclear plant accident.

The United Kingdom’s Nuclear Decommissioning Authority has announced that it will establish a Plutonium Ceramics Academic Hub with the Universities of Manchester and Sheffield. The announcement follows a decision by the U.K. government in January to immobilize the country’s inventory of civil separated plutonium at the Sellafield nuclear site, mitigating the material’s long-term safety and security risks.

Social media this past weekend streamed with reactionary posts following a drone strike last Friday at the site of the destroyed reactor from the 1986 Chernobyl accident. The drone—armed with a warhead—ripped a hole in the New Safe Confinement (NSC), a large structure built to prevent any radioactive release from the damaged reactor unit 4 and to protect it from any external hazard. The drone strike caused a fire that was still smoldering in places as of Monday morning, and left a hole larger than 500 square feet. Efforts continue to mitigate the consequences of the fire and extinguish isolated smouldering areas of the NSC's insulation material.

Due to damage to the external and internal cladding of the NSC's arch and main crane system equipment, the safety boundaries and operational conditions of the NSC complex have been compromised, according to the Chernobyl nuclear power plant Facebook page.

In the past year and a half, the International Atomic Energy Agency has established the Nuclear Security Training and Demonstration Center (NSTDC) to help countries strengthen their nuclear security regimes. The center, located at the IAEA’s Seibersdorf laboratories outside Vienna, Austria, has been operational since October 2023.

Williams

President Trump has selected Brandon Williams to head the Department of Energy’s National Nuclear Security Administration, pending confirmation by the U.S. Senate.

Williams is a former one-term congressman (R., N.Y.),from 2023 to the beginning of 2025. Prior to political office he served in the U.S. Navy. Williams’s run for office gained attention in 2022 when he defeated fellow navy veteran Francis Conole, a Democrat, but he lost the seat last November to Democrat John Mannion.

“I will be honored to lead the tremendous scientific and engineering talent at NNSA,” Williams said, thanking Trump, according to WSYR-TV in Syracuse, N.Y.

Pointing to the consequences of ignoring the perils of nuclear weapons, Rafael Mariano Grossi at last week’s Nobel Peace Prize forum called for diplomacy and dialogue to reduce nuclear tensions.

A drone targeted and damaged an official vehicle of the International Atomic Energy Agency on December 10 as it traveled toward the front line in eastern Ukraine during a rotation of IAEA teams at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP). In a video message, IAEA director general Rafael Mariano Grossi condemned the strike as an “unacceptable” attack on IAEA staff working to prevent a nuclear accident during a military conflict.

U.S. and Israeli officials are now confirming that an October 25 Israeli attack in Iran destroyed an active top secret facility for nuclear weapons research, Axios reports. The strike is said to have significantly hampered efforts by Iran to resume weapons research, despite ongoing denials from the country’s leaders that there is an active weapons program.

The International Atomic Energy Agency has reported that Ukraine’s operating nuclear power plants reduced electricity production yesterday morning as a precautionary measure following widespread military activities across the country that reportedly targeted its energy infrastructure.

The little-known Nuclear Emergency Support Team (NEST) was highlighted recently on the popular NPR show “All Things Considered” and was accompanied by an online feature.

A man killed in a car bomb last week in Enerhodar, Ukraine, may have been targeted because of his ties to Zaporizhzhia nuclear power plant.

The International Atomic Energy Agency received information from both the Russian Federation and Ukraine about the suspected assassination, which occurred in the town where most of the plant staff live, said IAEA director general Rafael Mariano Grossi.

A new report from the U.S. Government Accountability Office finds that the Nuclear Regulatory Commission has not taken the steps needed to address the potential economic and societal radiological risks that could arise from a “dirty bomb.”

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) is seeking qualified candidates for two open positions. The ACRS is the world’s oldest organization devoted to reactor safety and is statutorily mandated by the Atomic Energy Act of 1954, as amended. Today, the ACRS reports directly to the NRC’s commission and provides an independent expert technical review of and advice on matters related to the safety of existing and proposed nuclear facilities and on the adequacy of proposed reactor safety standards. The ACRS also advises the commission on health physics, radiation protection, and nuclear waste disposal facility issues.

The ACRS is a part-time advisory group consisting of a maximum of 15 members who are well-recognized experts in technical areas that are key to nuclear safety and whose membership represents a diverse breadth of experience in all aspects of the nuclear enterprise: industry, universities, national laboratories, and government.
