Tokyo Holdings Electric Power Company (HD) will begin discharging water treated with a multi-nuclear removal system (ALPS) at the Fukushima Daiichi Nuclear Power Plant into the ocean today as early as the 24th. Completed into the first stage for release on the 22nd. A very small amount of treated water is diluted with seawater and stored in an upstream water tank, after which the water is collected. We are currently analyzing the tritium concentration and will publish the results this morning. A final decision will be made on whether a release is possible, including whether sea conditions permit monitoring of the sea area.

The treated water in the storage tank is usually discharged by the following processes. First, the water is received into 10 measuring and validation tanks, and then recirculated and mixed to ensure uniform water quality. Then, samples were collected and analyzed for concentrations of nuclei, including tritium. After confirming that the discharge standards are met, it will be transferred to the upstream water tank by the pump. There are three measurement and validation tank systems, A through C, and a series of "acceptance", "measure/evaluate" and "discharge" procedures that are rotated over a period of approximately two months.
