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.

The sample chamber is equipped with a robotic arm capable of precisely positioning and orienting samples within the pulsed thermal neutron beam originating from the spallation target. This advanced setup enables simultaneous neutron diffraction and Bragg-edge imaging, allowing researchers to analyze the structural and microstructural properties of irradiated nuclear fuels under controlled conditions.

In materials science, understanding the unseen—how materials behave internally under real-world conditions—has always been key to developing new materials and accelerating innovative technologies to market. Moreover, the tools that allow us to see into this invisible world of materials have often been game-changers. Among these, neutron imaging stands out as a uniquely powerful method for investigating the internal structure and behavior of materials without having to alter or destroy the sample. By harnessing the unique properties of neutrons, researchers can uncover the hidden behavior of materials, providing insights essential for advancing nuclear materials and technologies.

Type One Energy said it has entered into a cooperative agreement with the Tennessee Valley Authority to jointly develop plans for a potential TVA fusion power plant project in the Tennessee Valley region using Type One Energy stellarator fusion power technology. The company said its 350-MWe fusion pilot power plant, named Infinity Two, could provide a complementary source of baseload electrical generation for the region as early as the mid-2030s.

The University of California–San Diego has joined a new research collaborative focused on overcoming critical obstacles in developing and scaling up inertial fusion power plants. Led by San Diego-based General Atomics, the group was one of six research teams that were collectively awarded $107 million in January by the Department of Energy as part of the Fusion Innovative Research Engine (FIRE) Collaboratives.

The top three utilities in Arizona are teaming up to explore opportunities to add nuclear generation facilities in the state.
Arizona Public Service (APS), Salt River Project (SRP), and Tucson Electric Power (TEP) announced in a February 5 news release that they are working together to assess possible sites, including retiring coal plants. The group is looking at possibilities for both small modular reactors—units generating 300 MW or less—and potential large reactor projects, which could generate nearly five times the power.

Imagine you’re constructing a bridge or designing an airplane, and everything appears flawless on the outside. However, microscopic flaws beneath the surface could weaken the entire structure over time.
These hidden defects can be difficult to detect with traditional inspection methods, but a new technology developed by scientists at the U.S. Department of Energy’s Argonne National Laboratory is changing that. Using artificial intelligence and advanced imaging techniques, researchers have developed a method to reveal these tiny flaws before they become critical problems.
