日本一停运核反应堆发生泄漏 或有数人遭辐射

Core Viewpoint - A radioactive water leak occurred at the "Puxian" nuclear reactor in Fukui Prefecture, Japan, which is currently undergoing decommissioning, potentially exposing several individuals to radiation [1][3]. Group 1: Incident Details - The leak involved water containing tritium, with a reported leakage volume of approximately 20 milliliters and a high concentration of radioactive material [3]. - No internal radiation exposure has been confirmed for the workers involved, but investigations are ongoing to determine if external radiation exposure occurred due to splashes [3]. - Monitoring stations in the facility and surrounding areas have not detected any abnormal radiation levels, indicating that the radioactive material has not leaked outside the management area [3]. Group 2: Related Nuclear Water Discharge - Tokyo Electric Power Company (TEPCO) reported that the 17th discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant was completed, with a total discharge volume of approximately 133,000 tons since the process began in August 2023 [4]. - The 17th discharge, which started on the 4th of the month, involved the release of 7,833 tons of contaminated water containing about 24 trillion becquerels of tritium [4]. - TEPCO plans to conduct a total of seven discharges in the fiscal year 2025, with an estimated total discharge volume of approximately 54,600 tons [4].
