Japan to Allocate Funds to Accelerate Preparations for Next-Generation Nuclear Reactor Reviews

The Nuclear Regulation Authority (NRA) of Japan has decided to include funding in its budget request for the next fiscal year to investigate the effectiveness of safety measures for next-generation nuclear reactors and to make advance preparations for future review work. The Japanese government is promoting the development of next-generation nuclear reactors, including innovative light-water reactors that enhance safety design based on existing light-water reactor technology. Since November last year, Kansai Electric Power Co. has been conducting geological surveys at the Mihama Nuclear Power Station in Fukui Prefecture as part of preliminary preparations for potentially replacing existing units with next-generation reactors in the future. It has been reported that the NRA plans to include in its budget request for the next fiscal year...

TEPCO replaces faulty motor of robotic arm at Fukushima Daiichi Unit 2

Tokyo Electric Power Company (TEPCO) began replacing the faulty motor of the robotic arm used for fuel debris retrieval trials at Unit 2 of the Fukushima Daiichi Nuclear Power Station on August 26. The robotic arm, approximately 22 meters long, is planned for use in the third fuel debris retrieval trial. During a previous operational inspection inside the reactor building of Unit 2, TEPCO found that the motor driving the robotic arm had malfunctioned, preventing the brake from releasing and the arm from extending. As the robotic arm is already installed on site, workers will enter the "front chamber" in front of the containment vessel to perform the replacement manually. The company stated that radiation levels in the work area will be strictly controlled to prevent workers from receiving excessive exposure. After this replacement, TEPCO will...

Japan Extends Deadline for Mandatory Anti-Terrorism Facility Installation at Nuclear Power Plants

The Nuclear Regulation Authority (NRA) of Japan formally decided at its regular meeting on August 26 to revise relevant regulations, extending the deadline for the mandatory installation of anti-terrorism facilities at nuclear power plants. The revised system is expected to be implemented in September. Under Japan's current regulatory requirements, nuclear power plants must be equipped with "specified severe accident response facilities" to address serious accidents that could potentially be triggered by extreme scenarios such as terrorist attacks. This revision shifts the starting point of the 5-year grace period from the date of approval of the detailed design and construction plan for the nuclear power plant to the date the plant officially commences commercial operation. This adjustment effectively relaxes the installation deadline requirements. The new rules will apply to nuclear power units that have not yet reached their installation deadlines. East...

Chubu Electric Power Suspected of Falsifying Decommissioning Progress at Hamaoka Nuclear Power Plant

According to disclosures, Japan's Chubu Electric Power Company (CEPCO) is suspected of submitting improper reports to the Japan Spent Fuel Reprocessing and Decommissioning Promotion Organization (NuRO), which manages decommissioning funds, during the cost declaration process for the decommissioning of Units 1 and 2 at the Hamaoka Nuclear Power Plant, overstating project progress and settling related costs accordingly. The Hamaoka Nuclear Power Plant is located in Omaezaki City, Shizuoka Prefecture, Japan. Chubu Electric Power decided to shut down Units 1 and 2 of the plant in 2008, with related decommissioning work commencing in 2009. Sources say that when declaring decommissioning project costs, the company is suspected of reporting project progress as faster than actual conditions and using inaccurate data in documents submitted to the fund management organization...

U.S. Army Plans to Deploy Over 20 Micro Nuclear Reactors at Military Bases

The U.S. Army has signed contracts with five companies to develop, build, and operate micro nuclear power plants at military bases, with a total contract value of up to $2.2 billion. According to relevant information, the U.S. Department of Defense requires the companies to construct, own, and operate more than 20 micro nuclear reactors at military installations by 2028. The plan is intended to enhance energy security for critical defense facilities and reduce dependence on the external power grid. The deployment is incorporated into the framework of the Janus Project, which the U.S. Army launched in 2025. The project aims to establish a power supply network composed of compact micro nuclear reactors at military bases, providing continuous and stable electricity to vital defense facilities....

US Advances Preparations for High-Burnup Spent Fuel Shipment to Idaho for Research

The U.S. Department of Energy (DOE) recently stated that the Idaho Cleanup Project (ICP) is participating in preparations for transporting a high-burnup spent nuclear fuel research cask. The cask is planned to be shipped from Dominion Energy's North Anna Nuclear Power Station in Virginia to the Idaho National Laboratory (INL) for subsequent spent fuel-related research. INL was selected as the receiving site primarily because it possesses the specialized facilities, equipment, and personnel expertise required for handling spent nuclear fuel. The DOE noted that these capabilities are typically not part of routine commercial nuclear power plant configurations. High-burnup fuel refers to nuclear fuel that remains in the reactor for a longer period to increase energy output...

U.S. Research Reveals Diamond Melting Mechanism at High Pressure, Potentially Enhancing Inertial Confinement Fusion Performance

A research team at Lawrence Livermore National Laboratory (LLNL) in the U.S. recently published a study in Nature Physics reporting that the latest dynamic compression experiments have, for the first time, directly recorded atomic structural changes during diamond melting under extreme high pressure. The experiments showed that under high-pressure conditions, solid diamond can float in liquid metallic carbon, similar to ice floating on water. Diamond is not only a high-hardness carbon material but is also used as the fuel target capsule shell in inertial confinement fusion experiments. When intense lasers drive the capsule implosion, the compression and melting behavior of the diamond shell can affect whether the fusion fuel reaches the required high-temperature, high-pressure state. Meanwhile, the planetary science community has long focused on the high-pressure behavior of carbon in the deep interiors of ice giant planets...

Bitumen Solidification Facility at Unit 2 of Japan's Ikata Nuclear Power Plant Returns to Normal

Shikoku Electric Power Co. reported on August 25, 2026, that the bitumen solidification facility at Unit 2 of Japan's Ikata Nuclear Power Plant, currently in a decommissioned state, had returned to normal operation at 10:45 a.m. that day. The gasket at the joint of the mixer top cover, where the earlier abnormality had been detected, had been replaced, and trial operation results showed no abnormalities. The incident occurred on April 28. On that day, when operators started the bitumen solidification facility in the controlled area of the reactor auxiliary building, they observed a steam-like phenomenon near the mixer thermometer, which subsequently disappeared on its own. Maintenance personnel later inspected and confirmed at 3:05 p.m. that the steam-like gas originated from inside the mixer and had escaped through the joint of the mixer top cover; at 5:06 p.m., the bitumen solidification facility was shut down.
