November 25, 2019

1. On 25 November, the Ministry of Foreign Affairs of Japan revised the information sheet released on 16 September on the situation of the ALPS-treated water at the TEPCO’s FDNPS, as attached (English (PDF)Open a New Window / Japanese (PDF)Open a New Window).

2. The Government of Japan (GOJ) prepared the information sheet initially in September to provide information to the international community in a courteous and transparent manner, focusing on the current situation of the ALPS-treated water stored at the FDNPS, which is the water where most of the radionuclides except for tritium have been removed, and the close and continuous cooperation between Japan and the IAEA in this area.

3. The GOJ aims at providing a clear explanation to the international community with regard to the differences between contaminated water and the ALPS-treated water, which are often confused. Particularly, in this update, the GOJ added specific explanation, such as the fact that the radioactive materials in the ALPS-treated water are reduced to about one millionth, compared to the water before purification as well as the remaining tritium in the water is diluted in advance so as to meet regulatory standards for discharge.

4. The GOJ continues to provide correct information to the international community based on scientific evidence.
