Japan to Establish New Decontamination Base in Okuma, Fukushima

Japan to Establish New Decontamination Base in Okuma, Fukushima

Japan's Ministry of the Environment has decided to establish a new work base in Okuma Town, Fukushima Prefecture, in the next fiscal year to coordinate decontamination and house demolition work in difficult-to-return zones following the accident at Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi Nuclear Power Station, aiming to accelerate environmental recovery in the affected areas. Within seven municipalities surrounding the Fukushima Daiichi Nuclear Power Station, approximately 309 square kilometers have been designated as difficult-to-return zones. These areas remain under strict control, with restrictions on residential habitation and entry, and evacuation orders remain in effect. Within the difficult-to-return zones, the Japanese government has established "specified return residential areas" and plans to advance decontamination, house demolition, and other measures based on residents' intentions to return. The proposed new base in Okuma Town will be responsible for on-site management and project coordination, with approximately 30 staff members expected to be assigned, and the relevant branch office currently located in Hirono Town will be relocated to Okuma Town.

Argentina Advances Testing for Atucha II Spent Fuel Dry Storage Project

Argentina Advances Testing for Atucha II Spent Fuel Dry Storage Project

Nucleoeléctrica Argentina S.A. is advancing key equipment testing for the spent fuel dry storage facility (ASECG II) at the Atucha II nuclear power plant. This project is a critical supporting infrastructure to ensure the long-term operation of the Atucha II plant. The ongoing tests are part of the verification phase prior to system commissioning, primarily aimed at inspecting and adjusting the operational procedures involved in future operations. Among the key equipment under testing is the gantry crane, which handles the transfer of storage containers within the plant site. The stable performance of this equipment is directly related to the safety and controllability of container movements during spent fuel storage operations. According to the project plan...

Hole of about 3 meters confirmed at bottom of reactor pressure vessel of Unit 3 at Fukushima Daiichi Nuclear Power Station

Hole of about 3 meters confirmed at bottom of reactor pressure vessel of Unit 3 at Fukushima Daiichi Nuclear Power Station

Tokyo Electric Power Company (TEPCO) announced on August 27 that a hole approximately 3 meters in diameter has been confirmed at the bottom of the reactor pressure vessel of Unit 3 at the Fukushima Daiichi Nuclear Power Station. The pressure vessel is a steel container that held nuclear fuel before the accident, with a cylindrical shape and a diameter of about 5.5 meters. This is the first time since the core meltdown accident at Units 1 to 3 of the Fukushima Daiichi Nuclear Power Station in 2011 that the specific size and shape of such a hole have been confirmed on the pressure vessel. The hole is believed to be related to the falling of melted nuclear fuel during the 2011 accident. After the accident, the containment vessel of Unit 3 has maintained a relatively high water level for an extended period, and access routes into the containment vessel are limited. TEPCO previously used a micro drone measuring approximately 12 centimeters per side...

German BESSY II Research Reveals: Cesium Chloride Seed Layer Can Improve Quality of Perovskite-Silicon Tandem Solar Cells

German BESSY II Research Reveals: Cesium Chloride Seed Layer Can Improve Quality of Perovskite-Silicon Tandem Solar Cells

A team from the Helmholtz-Zentrum Berlin (HZB) in Germany used the BESSY II synchrotron radiation facility to conduct nanoscale analysis of perovskite-silicon tandem solar cells fabricated by evaporation methods, and proposed a new approach to improve the quality of perovskite thin films. The study shows that introducing a thin cesium chloride (CsCl) seed layer between the two sub-cells promotes uniform growth of the perovskite layer while reducing undesirable lead iodide deposition at the interface. The research demonstrates that the cesium chloride seed layer improves the growth of the evaporated perovskite layer and reduces the formation of lead iodide. Scanning electron microscopy images show that the perovskite layer grown without a seed layer (left image) consists of extremely fine crystallites...

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

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 to Use Fukushima Decontaminated Soil at Government Office Buildings in Sendai and Saitama

Japan to Use Fukushima Decontaminated Soil at Government Office Buildings in Sendai and Saitama

At a Cabinet meeting held at the Prime Minister's Office on August 25, the Japanese government decided to use decontaminated soil generated from the Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Power Station accident for flower beds and other areas at joint government office buildings in Sendai City and Saitama City. This will mark the first use of such recycled soil outside Tokyo. According to the plan, the relevant office buildings will use a total of approximately 2 cubic meters of low-radioactivity "reconstruction recycled soil," with the specific construction schedule still being coordinated. The usage site in Saitama City is located at the government joint office building in the Saitama New Urban Center area, and Sendai City will also implement similar arrangements at its joint government office building. Under Japanese law, soil decontaminated after the Fukushima Daiichi Nuclear Power Station accident must be transported outside Fukushima Prefecture for final disposal by March 2045. The Japanese government hopes that by first using such soil in public facilities, it can promote the final disposal work outside Fukushima Prefecture and enhance public understanding of the safety and necessity of such soil.

Collective Radiation Dose of Workers at Japan's Fukushima Daiichi Nuclear Power Station Ranks Highest Nationwide

Collective Radiation Dose of Workers at Japan's Fukushima Daiichi Nuclear Power Station Ranks Highest Nationwide

Japanese nuclear power plant operators are required to submit radiation management reports to the Nuclear Regulation Authority (NRA) annually, detailing the exposure status of plant workers. According to the relevant 2025 reports, the collective radiation dose of workers at Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi Nuclear Power Station remains significantly higher than at other Japanese nuclear plants, indicating that the radiological impact from post-accident on-site decommissioning and management work is still ongoing. By collective dose per plant, Fukushima Daiichi recorded 20.97 person-sieverts, the highest in Japan. This figure is nine times the 2.22 person-sieverts reported at Kansai Electric Power's Takahama Nuclear Power Station...
