Investigation to Be Conducted into Emergency Diesel Generator Failure at Unit 6 of Japan's Kashiwazaki-Kariwa Nuclear Power Plant

Tokyo Electric Power Company announced that it will investigate the failure of the emergency diesel generator at Unit 6 of the Kashiwazaki-Kariwa Nuclear Power Plant in Niigata Prefecture, Japan. The unit was restarted after 14 years of shutdown and resumed commercial operation in April this year. According to Tokyo Electric Power Company, in July this year, workers discovered that water had mixed into the lubricating oil of the emergency diesel generator at Unit 6. Subsequent inspections confirmed that there was a water leak in the cylinder head, a component of the generator engine. The company therefore determined that the unit currently does not meet the operational safety specification requirements. Tokyo Electric Power Company stated that it plans to complete the relevant repair work by September 19. If the repair cannot be completed by then, the cause of the failure will be further investigated, and measures may include shutting down the reactor for inspection.

Japan's Monju Fast Breeder Reactor Sodium Coolant Overseas Transport Planned to Start in Fiscal 2028

Japan's Ministry of Education, Culture, Sports, Science and Technology plans to include 23.7 billion yen in its fiscal 2027 budget request to advance decommissioning work for the Monju fast breeder reactor in Tsuruga City, Fukui Prefecture, including preparation costs for overseas transport of sodium coolant. The amount represents an increase of 4.9 billion yen over the previous fiscal year's budget, including supplementary budgets. Under the plan, overseas transport of sodium coolant from the Monju reactor will begin in fiscal 2028. Unlike conventional light water reactors, Monju uses metallic sodium rather than water as a coolant to remove heat from the reactor. Sodium has a boiling point of approximately 880 degrees Celsius and does not easily pressurize at high temperatures, but it can burn upon contact with water or air, making handling and management highly difficult...

Decommissioning of Unit 1 at Japan's Ikata Nuclear Power Plant Proposed to Move to Phase 2

On the 11th, Ichiro Ogi, Mayor of Yawatahama City in Ehime Prefecture, Japan, reported to the prefectural government that he has agreed to the decommissioning work of Unit 1 at the Ikata Nuclear Power Plant of Shikoku Electric Power Company entering Phase 2. Ichiro Ogi requested that Shikoku Electric Power thoroughly implement relevant measures during the subsequent decommissioning process to prevent the spread of radioactive materials, control the radiation exposure dose of workers, and protect the surrounding environment of the nuclear power plant. Unit 1 at the Ikata Nuclear Power Plant ceased operation in 2016, and since 2017, decommissioning work has been carried out in four phases, with a planned duration of more than 40 years. Currently, the decommissioning work of this unit is still in Phase 1. According to the safety agreement arrangements, Shikoku Electric Power has submitted a prior consultation application to the Ehime Prefectural Government...

Chubu Electric Power considers withdrawing Hamaoka nuclear plant restart review application

Chubu Electric Power Company (CEPCO) is considering withdrawing its restart review application for Units 3 and 4 of the Hamaoka Nuclear Power Plant. The plant is located in Omaezaki City, Shizuoka Prefecture, Japan, and it was previously revealed that seismic design data related to the restart review was suspected of falsifying "design basis ground motion" data, making the ground motion amplitude in the submitted materials lower than originally expected. On the morning of the 11th, Chubu Electric Power announced that it had received a report submitted by an investigation committee composed of external lawyers. The committee was commissioned by Chubu Electric Power to investigate the causes and process of the seismic design data issue at the Hamaoka Nuclear Power Plant. Chubu Electric Power President Shingo Hayashi and others plan to hold a press...

CGN's 33 in-operation nuclear power units achieve RMB-denominated pricing and settlement for operational period insurance

On September 10, the "CGN In-Service Nuclear Power Plant Operational Period Insurance Project Co-Insurance Agreement" was signed in Shenzhen. The agreement achieves RMB-denominated pricing and settlement for major types of nuclear power plant operational period insurance, changing the convention of China's nuclear insurance market's over thirty years of primarily relying on foreign currency transactions. Nuclear insurance is an important type of insurance for ensuring the safe and stable operation of nuclear power units. Due to the enormous insured amount of a single policy, it typically requires joint underwriting by hundreds of insurance companies both domestically and internationally, and is regarded by the insurance industry as one of the most special and complex types of insurance. Since China's first nuclear power plant operational insurance policy——the Daya Bay Nuclear Power Plant operational insurance policy——was issued in 1993, China's nuclear power industry has long followed mature foreign models...

Yanchaojuneng Completes VPI of Stainless Steel-Jacketed Superconducting Prototype Coil for Stellarator

Recently, Yanchaojuneng (Shanghai) Technology Co., Ltd. completed vacuum pressure impregnation (VPI) of a next-generation stellarator stainless steel-jacketed three-dimensional shaped superconducting prototype coil. Previously, the prototype coil had completed two core processes: three-dimensional precision winding and ground insulation wrapping. The completion of VPI signifies that the company has established an autonomous process chain from coil winding and forming, insulation wrapping, to integrated insulation curing. The stellarator is an important device type for steady-state operation in the field of controlled nuclear fusion, capable of reducing the risk of major plasma disruptions. Three-dimensional shaped superconducting coils are the core components for building the magnetic field that confines plasma in a stellarator. Public information shows that Germany's W7-X stellarator uses aluminum alloy jackets...

NASA's Chandra Telescope Discovers 84 Mysterious Supersoft X-ray Sources

NASA's Chandra X-ray Observatory recently announced that researchers using the observatory's publicly available observation data discovered 84 mysterious celestial objects known as supersoft X-ray sources in 6 galaxies. The related research was published in Nature Astronomy. Image credit: X-ray: NASA. These objects emit X-rays with unusually low energy and may be accompanied by strong high-energy ultraviolet radiation. The research team stated that the behavior of these objects is clearly different from previously observed known celestial bodies and may provide new clues for explaining the origin of Type Ia supernovae and the electron-stripping mechanism in the intergalactic medium. The 6 galaxies covered by this search include two spiral...
