Fukushima Daiichi ALPS Treated Water Discharge - Timeline of IAEA Safety Reviews for ALPS-Treated Water Discharge

Advanced Liquid Processing System (ALPS)

In April 2021, Japan announced the Basic Policy on handling of  ALPS-treated water stored at the Fukushima Daiichi Nuclear Power Station, which is to discharge  ALPS-treated water into the sea surrounding the plant, subject to domestic regulatory approvals.

Soon after, the Japanese authorities requested technical assistance from the IAEA to monitor and review those plans and activities related to the discharge of  ALPS-treated water to ensure they will be implemented in a safe and transparent way.

The IAEA will conduct this review against the IAEA Safety Standards, which constitute harmonized high levels of safety worldwide and, as such, a global reference for protecting people and the environment.
