IAEA9月理事会(議題3 原子力・放射線安全)ステートメント(引原毅大使)(英語)

Thank you, Chair,
Let me first join previous speakers to express our heartfelt sympathy to the victims of the devastating earthquakes which hit the Kingdom of Morocco over the weekend. As Prime Minister Kishida said yesterday, Japan stands by the people and the government of the Kingdom of Morocco and ready to provide support in any possible way.
Japan highly appreciates the Agency’s activities described in the Director General’s report entitled ‘Nuclear and Radiation Safety’. Japan thanks Director General Grossi, Deputy Director General Evrard and her team for their tireless efforts. The Agency’s wide-ranging activities are essential in enhancing nuclear safety among Member States.
Japan continues to commit itself to the Convention on Nuclear Safety, as well as the Joint Convention. We welcome the outcome of the Joint Eighth and Ninth Review Meetings of the Contracting Parties to the Convention on Nuclear Safety which was held in March this year.
My delegation also attaches great importance to IAEA Safety Standards. We appreciate the work of the Secretariat and all experts from Member States, including Japan, in establishing and revising the Safety Standards.
Japan has continuously supported, including by financial means, the Regulatory Cooperation Forum and the Asian Nuclear Safety Network to develop and strengthen the nuclear regulatory framework. As is mentioned in the DG’s report, the University of Tokai in Japan worked together with the IAEA in February and March to host the International School of Nuclear and Radiological Leadership for Safety. Japan also coordinated with the IAEA to hold in Japan the National Workshop on Emergency Preparedness and Response in February, and the Workshop on Safety Culture Self-Assessment for Regulatory Bodies in February to March.
Japan remains committed to contributing to enhance global nuclear safety, while further improving its own nuclear regulatory framework.
With regard to TEPCO’s Fukushima Daiichi Nuclear Power Station, I would like to provide the latest information of the ALPS treated water.
Let me first express my gratitude to our colleagues who already expressed their support to our efforts and to the Agency’s related review and monitoring exercise.
Japan has been taking all measures strictly in accordance with relevant international law as well as giving due consideration to international practice, while undergoing the review by the IAEA and engaging with the international community in a highly transparent manner based on scientific evidence. On July 4th this year, the IAEA published its Comprehensive Report, which concludes that the approach and activities for its discharge are consistent with relevant international safety standards and that the discharge will have a negligible radiological impact on people and the environment.
On August 24th, Japan started discharging ALPS treated water into the sea. Since the start of the discharge, it has been confirmed that the concentration of nuclides including tritium in sea water and marine products are far below the standards, which demonstrates that the discharge has been carried out safely as planned.
Japan is now implementing three types of monitoring in a multilayered manner with the involvement of the IAEA; Monitoring of treated water in tanks before dilution, Real time monitoring before discharge and Sea area monitoring after discharge. The results of these monitoring by the Government of Japan and TEPCO have been and will continue to be made public in a timely manner. These results reaffirm, as I mentioned before, that the discharge is safe.
If, by any chance, an unexpected event occurs, such as detecting radioactivity levels exceeding specific standards, which are far stricter than the domestic regulatory standards as well as the international standards, appropriate measures will be taken including suspending the discharge.
Japan highly appreciates that the IAEA is committed to continuing its impartial, independent, and objective safety review during the discharge phase. As part of it, the IAEA team is present at the site to monitor the discharge and assess Japan’s application of all relevant international safety standards for the water discharge.
The IAEA’s first independent sampling and analysis of seawater near the Fukushima Daiichi Nuclear Power Station after the discharge confirms that the tritium levels are below Japan’s operational limit. It shows consistency with the values reported by TEPCO as well as the Ministry of Environment of Japan.
Japan will continue to make every effort to ensure safe discharges, with the continued involvement of the IAEA, including its independent reviews. Japan will also continue to provide necessary information including the results of the monitoring to the international community in a timely and transparent manner and will continue its efforts to further expand proper understanding on our handling of the issue in the international community.
The situation at Ukraine’s nuclear facilities as a result of Russia’s actions has been a matter of great concern, from the perspective of nuclear safety, security, and safeguards. The aggression by the Russian Federation and its related actions must be condemned in the strongest terms. Japan expresses its appreciation to Director General Grossi and his team for their dedicated efforts related to Ukraine. In this regard, we reiterate the importance of the IAEA Director General’s “seven indispensable pillars on nuclear safety and security” derived from IAEA safety standards and nuclear security guidance. Japan also supports the IAEA’s “five principles” to help ensure the nuclear safety and security at Ukraine’s Zaporizhzhya Nuclear Power Plant.

Before concluding, let me echo the concern expressed by Director General Grossi on the financial situation of the Agency. I hope we would come back to this critical issue under AOB.
With these comments, Japan takes note of the report contained in GOV/2023/36.
Thank you, Chair.
