A | TOKYO -- The operator of the Fukushima Daiichi nuclear power plant said the discharge of the second batch of treated radioactive wastewater into the sea ended as planned on Monday, and International Atomic Energy Agency officials in Japan for their first safety and monitoring mission since the release began two months ago said “no issues” were observed.Fukushima Daiichi started releasing treated and diluted radioactive wastewater into the sea on Aug. 24. The operator, Tokyo Electric Power Company Holdings, said the release of a second, 7,800-ton batch of treated wastewater was completed, with its daily seawater sampling results fully meeting safety standards.A magnitude 9.0 quake on March 11, 2011, triggered a massive tsunami that destroyed the plant’s power supply and cooling systems, causing three reactors to melt and spew large amounts of radiation. Highly contaminated cooling water applied to the damaged reactors has leaked continuously into building basements and mixed with groundwater.The release of treated wastewater is expected to continue for decades. It has been strongly opposed by fishing groups and neighboring countries including South Korea, where hundreds of people have protested. China banned all imports of Japanese seafood the day the release began, badly hurting Japanese seafood producers, processors and exporters. Russia recently joined China in the trade restrictions.“I would say that the first two batches of releases went well. No issues were observed," Lydie Evrard, IAEA deputy director general and head of the department of nuclear safety and security, told a Tokyo news conference. She said she visited Fukushima Daiichi on Friday for a firsthand look.Evrard's visit came on the heels of a marine sampling mission by another IAEA team that included scientists from China, South Korea and Canada. She said all participants in that mission said their activity went well. She did not say whether Chinese scientists acknowledged the safety of the release.She said China has been involved in the IAEA safety task force since the beginning of the review that began two years ago and has participated in corroboration activities. The IAEA is aware of China’s concern and engaged with its authorities, Evrard said.Japanese Prime Minister Fumio Kishida, in his policy speech Monday, renewed his call for China to immediately lift its ban on Japanese seafood imports.During the Oct. 16-23 visit, the IAEA sampling team collected seawater, sediment and fish from near the plant and visited a marine laboratory near Tokyo that makes fish specimens for radiation analysis by institutions in and outside Japan, including the IAEA.During Evrard's visit, IAEA task force and Japanese officials are expected to discuss the safety of the ongoing discharge and their future mission plans, with a report expected by the end of the year. She said the discharge plan would be updated with new findings and data collected over the past two months.The IAEA, based on its two-year review of TEPCO's wastewater release plan, concluded in July that if it is carried out as planned, it will have a negligible impact on the environment, marine life and human health.Japan’s government and TEPCO say the discharge is unavoidable because wastewater storage tanks at the plant will be full next year. They say the water produced by the damaged plant is treated to reduce radioactivity to safe levels, and then diluted with massive amounts of seawater to make it much safer than international standards.TEPCO has said it plans to release 31,200 tons of treated water by the end of March 2024, which would empty only 10 tanks out of 1,000 because of the continued production of wastewater at the plant.。 8月24日电 据工信部网站消息,为加强人形机器人标准化工作系统谋划,工业和信息化部组织编制形成《国家人形机器人产业标准体系建设指南(2026版)》(征求意见稿)。 征求意见稿提出,建立健全人形机器人标准体系,重点突破基础共性、类脑与智算、肢体与部组件、整机与系统、应用、安全伦理等领域标准研制。到2028年,创新探索标准研制工作模式,建成系统科学、协调配套的标准体系。在人形机器人能力测试及评估方法、关键技术、平台与系统、场景应用、安全治理等方面完成至少100项关键标准制定,开展标准宣贯和实施推广的企业超过200家,为人形机器人产业高质量发展提供坚实支撑。 征求意见稿将于8月25日至9月23日向社会公开征求意见。
