国际原子能机构(原子能机构)正在其网站上提供来自日本的有关福岛第一核电站处理水排放的实时数据。提供的数据包括水流量、辐射监测数据和稀释后的氚浓度。

作为福岛第一核电站的营运者,日本东京电力公司今天开始将先进液体处理系统处理水有控制地排放入海。与此同时,东京电力公司开始向原子能机构传输该过程中各个环节的数据。

原子能机构正继续对日本排放贮存在福岛第一核电站的水进行公正、独立和客观的安全审查。

原子能机构于7月4日发布了关于对福岛第一核电站先进液体处理系统处理水的安全审查情况的综合报告。在该报告中,原子能机构得出结论认为,日本采取的先进液体处理系统处理水排放方案和活动符合相关的国际安全标准。报告指出,按照东京电力公司目前的规划和评估,将处理水有控制地逐步排海对人和环境产生的放射性影响可以忽略不计。

除现场监测外,原子能机构还将通过持续的现场存在,在排放阶段继续进行安全审查,从而履行原子能机构总干事格罗西关于在排水之前、之中和之后都会参与其中的承诺。

原子能机构的专家将在现场观察与先进液体处理系统处理水排放有关的活动,包括采样和测量,并将与东京电力公司和日本原子力规制委员会的官员互动。原子能机构还将定期组织审查工作组访问,以观察现场活动,并要求日本当局提供最新情况和补充数据。

原子能机构的独立确证活动也将在整个排放过程中继续进行,预计将持续数十年,并将有原子能机构实验室和第三方实验室参与其中。随着时间的推移,原子能机构将展示对源监测和环境监测的这种独立确证结果,以及其对日本相关个人职业辐射防护监测服务能力的确证结果。结果将公布在网站上,以便有关各方更好地获取相关数据。

原子能机构先进液体处理系统安全审查主任兼协调员、特别工作组主席Gustavo Caruso说:“所有这些活动加在一起,将全面描述在福岛第一核电站进行的与先进液体处理系统处理水排放有关的活动,以及这些活动是否符合相关的国际安全标准。”“东京电力公司提供以及东京电力公司和原子能机构展示的数据,只是整体监测方案和原子能机构正在进行的安全审查中的一个部分。”

The Agency issued its comprehensive report on the safety review of the ALPS-treated water at the FDNPS on 4 July. In the report, the IAEA concluded that Japan’s approach and activities to discharge ALPS-treated water are consistent with relevant international safety standards. The report noted that the controlled, gradual discharges of the treated water to the sea, as currently planned and assessed by TEPCO, would have a negligible radiological impact on people and the environment.

In addition to the live monitoring, the IAEA will continue its safety review during the discharge phase by having a continuous on-site presence, meeting IAEA Director General Grossi’s commitment to be involved before, during and after the water discharges.

The IAEA experts will observe onsite activities related to the ALPS-treated water discharge, including samples and measurements, and will interface with TEPCO and officials from Japan’s Nuclear Regulation Authority (NRA). The IAEA will also organize review missions periodically to observe activities on site and to request updates and additional data from Japanese authorities.

The IAEA’s independent corroboration activities will also continue during the entirety of the discharge, expected to take decades, and will involve IAEA laboratories and third-party laboratories. Over time, the IAEA will display the results of this independent corroboration of source and environmental monitoring, as well as the results of its corroboration of the capabilities of relevant Japanese individual monitoring services for occupational radiation protection. The results are published on the website to enhance the availability of relevant data for interested parties.

“All of these activities will work together to provide a comprehensive picture of the activities taking place at FDNPS related to the ALPS-treated water discharge and whether these activities are consistent with relevant international safety standards,” said Gustavo Caruso, Director and Coordinator for the ALPS Safety Review at the IAEA and Chair of the Task Force. “The data provided by TEPCO, and displayed both by TEPCO and IAEA, is just a single piece of the overall monitoring approach and the IAEA’s ongoing safety review.”
