August 21, 2023
On July 31, the Government of Japan received a joint letter of questions from the People's Republic of China and the Russian Federation concerning the discharge of ALPS treated water into the sea at TEPCO's Fukushima Daiichi Nuclear Power Station, and provided a response dated August 18.
- On July 31, the Government of Japan received a joint letter of questions from the People's Republic of China and the Russian Federation regarding the discharge of ALPS treated water into the sea from TEPCO's Fukushima Daiichi Nuclear Power Station.
- On August 18, the Government of Japan responded to the joint letter of questions from the People's Republic of China and the Russian Federation. (The answers have been posted on the IAEA website)
- Last year, the Government of Japan received two joint letters of questions from the People's Republic of China and the Russian Federation, and in each case, the Government of Japan responded based on scientific evidence in a sincere manner.
- The Government of Japan continues to explain the safety of ALPS treated water and the situation at TEPCO's Fukushima Daiichi Nuclear Power Station to the international community in a courteous and transparent manner in close collaboration among relevant ministries and agencies.
[Reference] ALPS treated water is water which is processed by devices such as ALPS (Advanced Liquid Processing System) to ensure that the radioactive materials other than tritium surely meet the regulatory standards for safety. In addition, it is planned that ALPS treated water will then be sufficiently diluted before the discharges so that the concentrations of the radioactive materials including tritium will be far below the regulatory standards for safety.
