Data from Fukushima Daiichi ALPS Treated Water Discharge

Legend

Green – a numerical value and a green dot indicate that this aspect of the discharge system is operating currently and that the data being reported from TEPCO to the IAEA is within the expected levels.

Grey – a grey dot indicates that this aspect of the discharge system is not currently operating.  This does not indicate a problem, but rather that some aspect of the system is not currently “online.”  This could be due to routine maintenance or operational considerations (e.g., only one out of three pumps is actually being used).

Red – a numerical value and a red dot indicate that the data being reported from TEPCO to the IAEA is at an abnormal level which has required TEPCO action.
