TEPCO Starts Removing Strontium from Contaminated Water at Fukushima Daiichi NPS
On January 10, the Tokyo Electric Power Co., Inc. (TEPCO) started operating a reverse-osmosis treatment system to remove strontium from contaminated water at the Fukushima Daiichi NPS.
Currently, various measures to remove contaminants are in operation or currently undergoing trial operations. They include the Advanced Liquid Processing System (ALPS) — multi-nuclide removal equipment that can extract 62 nuclides from contaminated water — along with a newer, higher-performance ALPS system.
The reverse-osmosis equipment (see photo) is one of several multiple risk-reduction measures being taken by TEPCO. The target is for it is eventually to treat some 500 to 900 cubic meters of contaminated water per day, reducing strontium levels to between one-hundredth and one-thousandth of their original levels.
