• The 5th report
• (1) IAEA Task Force Issues New Report on Regulatory Aspects of Water Discharge at Fukushima Daiichi
• (2) Report 5: Review Mission to NRA (PDF)

[Reference 1] ALPS treated water is water which is processed by devices such as ALPS (Advanced Liquid Processing System) to ensure that the concentration of 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 into the sea so that concentration of all radioactive materials including tritium will be far below the regulatory standards for safety.
