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.

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...
