Measurement and Analysis Results for Contaminated Water Treatment
Note on “Water treated with multi-nuclide removal equipment, etc.” is notated. (revised in March, 2020)
- Treated water for which the sum of concentration ratios required by law, with the exception of tritium, is less than 1 is notated as either, “water treated with multi-nuclide removal equipment, etc.” or “treated water”.
- Treated water that has not been completely treated is notated as, “water treated with multi-nuclide removal equipment, etc. (for which the sum of concentration ratios required by law equals or exceeds 1)”.
- When referring to both of the aforementioned types of treated water collectively, the notation, “treated water*” is used.
Main measurements/Analysis results
- (1) Groundwater inflow into the buildings: 70m3/day (as of July 29, 2024)
Please see here for the latest data. - (2) Amount of accumulated water from buildings being stored: Approx. 20,761 m3 (as of July 25, 2024)
Please see here for the latest data. - (3) Radioactivity concentration of treated water* at the outlet of multi-nuclide removal facility (outlet concentration)
Please see here for data on treated water* sampled from the outlet of the multi-nuclide removal facility. - (4) Radioactivity concentration of water treated with multi-nuclide removal facility (treated water*) (for each tank group)
Please see here for the radioactivity concentration of water in each storage tank area. - (5) Storage amount of water treated with multi-nuclide removal facility, etc.
Please see the treated water portal site for the amount of water treated with multi-nuclide removal facility and strontium-treated water being stored.
*Please see item (4) here for the analysis results for 62 nuclides (Japanese only).
Please see the treated water portal site for data and information on "treated water" resulting from the purification of contaminated water.
