Seawater taken from Unit 1 to 4 side of South Discharge Channel (November, 2013)
The day colored dates in this calender indicate the latest updated dates.
Nuclide analysis is in operation on the radioactive materials in the water sampled near the South Discharge Channel (approximately 330m south of Unit 1-4 side of the South Discharge Channel) in response to the leaked water from the pipeline connecting from Desalination System (Reverse Osmosis Membrane) to Concentrated Water Storage Tank (occurred on March 26 and April 5, 2012).
* The sampling location has been changed on November 26, 2012. (Sampling is performed at approx. 1km south of the previous location.)
