Japan's Plutonium Stockpile Expected to Remain at 44.4 Tons by End of 2025
Japan's Cabinet Office reported to the Japan Atomic Energy Commission (JAEC) on August 5 that Japan's plutonium stockpile is expected to be 44.4 tons by the end of 2025, unchanged from the end of the previous year. By source, domestically sourced plutonium stockpile is expected to be 9.9 tons, while overseas-sourced plutonium stockpile is 34.5 tons. The overseas-sourced plutonium mainly comes from separated plutonium formed after Japan entrusted its spent fuel reprocessing operations to the United Kingdom and France. The report shows that in 2024, Kansai Electric Power Company (KEPCO) processed 1.3 tons of plutonium stored in France into mixed uranium-plutonium oxide fuel, namely MOX fuel, resulting in a decrease in overseas-sourced plutonium stockpile. Subsequently, this batch of MOX fuel was shipped to the Takahama Nuclear Power...

Water Leak at Pipe Joint of Primary Cooling Pump in Unit 2 of Takahama Nuclear Power Plant; Kansai Electric Confirms No Radioactive Impact
Kansai Electric Power announced on August 3 that a water leak was found at a cooling water pipe joint in Unit 2 of the Takahama Nuclear Power Plant in July. According to Kansai Electric Power, an inspection crew discovered the issue during a check inside the intermediate building on July 11, with a leak volume of approximately 3.4 liters, and repairs were carried out on the 14th. The leak occurred at the pipe connection of the No. 1 cooling water pump during a periodic inspection. The pipe has an outer diameter of 2 centimeters, is secured by threaded fittings, and was sealed with sealing tape. Kansai Electric Power preliminarily determined that the leak may have been caused by tape deterioration due to friction or insufficient wrapping. Currently, Kansai Electric Power re-wrapped the sealing tape on the 14th, and Unit 2 of the Takahama Nuclear Power Plant resumed normal operation on July 16, with no other abnormalities identified to date. It is worth noting that the taped section had undergone a disassembly inspection in 2018, when the plant was in a long-term shutdown state.
