[Reference 1] ALPS treated water is water which is processed by devices such as ALPS (Advanced Liquid Processing System) to ensure that the radioactive materials other than tritium surely meets the regulatory standards for safety. In addition, it is planned that ALPS treated water will then be sufficiently diluted before the discharges.
