What is ALPS Treated Water?
-
1. Water treated with multi-nuclide removal equipment (ALPS) so that the concentrations of radioactive materials other than tritium sufficiently satisfy regulatory standards for safety (sum of the ratios to regulatory concentration limits excluding tritium, is less than 1) shall be referred to as, “ALPS treated water.”
-
2. Water that has been purified with multi-nuclide removal equipment (ALPS), but for which the concentrations of radioactive materials do not meet regulatory standards for safety (sum of the ratios to regulatory concentration limits excluding tritium, is 1 or higher) shall be referred to as, "Treated water to be re-purified."
-
3. The term “ALPS treated water, etc.” shall be used when referring to both types of water defined in 1. and 2. above.
