原子能机构总干事拉斐尔·马里亚诺·格罗西今天在东京告诉首相岸田文雄，原子能机构承诺独立监测福岛第一核电站计划的处理水排放入海，并将向日本政府和国际社会提供定期评定结果。
这次会议在格罗西先生昨天访问福岛第一核电站之后举行，这是为期三天日本访问的一部分。格罗西先生查看了处理水排放的准备工作，并指出“自我两年前的上次访问以来，福岛第一核电站的退役工作取得了显著进展”。
原子能机构正按相关国际安全标准审查日本的福岛第一核电站处理水排放政策。
格罗西在日本表示，原子能机构承诺监测福岛第一核电站处理水排放
原子能机构总干事拉斐尔·马里亚诺·格罗西今天在东京告诉首相岸田文雄，原子能机构承诺独立监测福岛第一核电站计划的处理水排放入海，并将向日本政府和国际社会提供定期评定结果。
岸田先生在会后的新闻发布会上说：“原子能机构对排放入海持续进行科学审查和客观审查，这是一项极其重要的工作，旨在获得国内外公众的理解。日本打算继续保持最高透明度，以此作为回应；我们期待继续与原子能机构合作。”
今年2月，原子能机构特别工作组完成了对福岛第一核电站营运者——日本东京电力公司以及经济、贸易和产业省（经济产业省）的工作组访问。格罗西先生说：“日本在准备工作上取得了重大进展，东京电力公司和经济产业省已为预定于2023年进行的水排放确定了适当的后续步骤，原子能机构特别工作组对此感到满意。原子能机构承诺在处理水排放之前、期间和之后提供全面安全审查，以客观和透明的方式开展我们的工作。”

原子能机构特别工作组4月发布了首份报告，总结了原子能机构对东京电力公司拟议水排放准备工作的安全审查的总体进展。报告指出了需要进行更多讨论和提供更多信息的技术领域，如对处理水的放射性表征以及对异常事件和外部危险的考虑。拟议排放入海的处理水经过了被称为先进液体处理系统的过滤过程的处理。先进液体处理系统是一系列化学反应，旨在去除受污染水中的绝大多数放射性核素。特别工作组还指出了确定先进液体处理系统处理水中放射性核素存量以及将排放到环境中的数量的重要性。
格罗西先生说：“展望未来，原子能机构计划开展更多活动，进行更多工作组访问，对处理水和环境样品进行独立取样和分析，以证实来自日本的数据，并评价工作人员在现场受辐射照射的情况。计划2022年下半年进行特别工作组的第二次工作组访问，该工作组由原子能机构工作人员和来自各国的国际认可的独立专家组成。这次工作组访问将就东京电力公司和经济产业省在技术专题上的进展开展后续工作，并审查经修订的辐射环境影响评定。
除周五与岸田首相会晤之外，格罗西先生还会见了外务大臣林芳正（他宣布为 乌克兰核安全和核安保 认捐200万欧元，为“希望之光”倡议认捐100万欧元，以解决全球在获得癌症护理方面的不平等）、科技政策担当大臣小林鹰之和原子力规制委员会委员长更田丰志。周四，格罗西先生会见了日本经济产业大臣萩生田光一，后者承诺为玛丽·斯克洛多夫斯卡-居里进修计划提供100万欧元的捐款，这是原子能机构的一项旗舰倡议，旨在增加女性在核领域的代表性。
本周早些时候， 格罗西先生会见了日本企业，请其支持“希望之光”。
“The continued scientific review and objective review by the IAEA regarding the discharge into the ocean is an extremely significant effort in order to gain an understanding for the public, both at home and abroad,” Mr Kishida said at a press conference following the meeting. “Japan intends to continue to respond with utmost transparency; we look forward to continue working with the IAEA.”
In February this year, the IAEA Task Force completed a review mission to Japan’s Tokyo Electric Power Company (TEPCO), the operator of Fukushima Daiichi, and the Ministry of Economy, Trade and Industry (METI). “Japan has made significant progress in its preparations, and the IAEA Task Force is satisfied that TEPCO and METI have identified the appropriate next steps for the water discharge scheduled for 2023,” Mr Grossi said. “The IAEA is committed to providing a thorough safety review before, during and after the release of treated water and to carrying out our work in an objective and transparent manner.”

The IAEA Task Force released its first report in April, summarizing the overall progress of the IAEA’s safety review of TEPCO’s preparations for the proposed water discharge. The report noted technical areas where additional discussions and information are warranted, such as the radiological characterization of the treated water and the consideration of abnormal events and external hazards. The treated water that is proposed for discharge into the sea is the result of a filtration process known as Advanced Liquid Processing System (ALPS). ALPS uses a series of chemical reactions to remove most radionuclides from contaminated water. The Task Force also noted the importance of identifying the inventories of radionuclides in ALPS-treated water and the amounts that will be discharged to the environment.
“Looking ahead, the IAEA has many more activities planned – additional missions, independent sampling and analysis of the treated water and environmental samples to corroborate data from Japan, and the evaluation of workers’ radiation exposure on site,” Mr Grossi said. A second mission of the Task Force, which includes both IAEA staff and independent, internationally recognized experts from various countries, is planned for the second half of 2022. This mission will follow up on TEPCO and METI’s progress on technical topics, as well as review the revised radiological environmental impact assessment.
In addition to meeting with Prime Minister Kishida on Friday, Mr Grossi met Foreign Minister Yoshimasa Hayashi – who announced pledges of €2 million towards nuclear safety and security in Ukraine and €1 million for the Rays of Hope initiative to tackle the global inequity in access to cancer care – Minister of State for Science and Technology Policy Takayuki Kobayashi and Toyoshi Fuketa, Chairman of the Nuclear Regulation Authority. On Thursday, Mr Grossi met with METI Minister Koichi Hagiuda, who pledged a contribution of €1 million towards the Marie Slodowska-Curie Fellowship Programme, a flagship IAEA initiative to increase the representation of women in the nuclear field.
Earlier this week, Mr Grossi met with Japanese companies, inviting them to support Rays of Hope.
