About ALPS treated water, tritium, and monitoring
In conducting the dilution and discharge of ALPS treated water into the sea, Tokyo Electric Power
Company Holdings, Inc. has set a "Discharge suspension level" as a benchmark for deciding to
"suspend discharge" in the event where monitoring of the local sea area indicates that the
discharged water hasn't sufficiently dispersed and so on.
The sea discharge will be immediately suspended if this level is exceeded.
No significant change has been detected. (as of Oct 31, 2023).
