(Reference2) ALPS treated water
ALPS treated water is water that contained radioactive substances from inside the buildings of TEPCO’s FDNPS and has been purified and treated through multiple treatment facilities, including ALPS (Advanced Liquid Processing System), until the concentrations of all radioactive substances besides tritium satisfy the safety regulatory standards. As for tritium, the water is significantly diluted with seawater before the discharge into the sea so that it fully satisfies safety regulatory standards.
