[NOTE] ALPS treated water
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 radioactive materials including tritium will be far below the regulatory standards for safety.
