Announcement Regarding Analysis Results of Tritium Concentration in Seawater Sampled After the Start of Discharge of ALPS Treated Water
(METI : August 25, 2023)

 

On August 22, 2023, Government of Japan held Inter-Ministerial Council, confirmed that it would take full responsibility for ensuring safety, countermeasures against reputational damage, and support for the continuation of livelihoods, until the discharge of ALPS treated water is completed, and indicated that the discharge into the sea is expected to start on 24 August.
 
In response, Tokyo Electric Power Company Holdings (TEPCO) started the discharge at 1:03 pm on the same day.
 
After the start of discharge, TEPCO sampled seawater at 10 locations within 3 km of the Fukushima Daiichi Nuclear Power Plant and quickly measured tritium concentration. As a result, the tritium concentration was below the detection limit, confirming that there was no unusual situation.
 
The results of analysis of tritium concentration in seawater are available on a special website of the Ministry of Economy, Trade and Industry (METI), which shows the results in the form of a mark that can be recognized at a glance.
 

1. Overview of Seawater Analysis

 

(1) Sample Collection

TEPCO has collected seawater samples at 10 locations within 3 km of the Fukushima Daiichi Nuclear Power Plant after the start of the discharge on August 24.
 

(2) Analysis Results

At all locations, tritium concentrations were found to be below the detection limit (detection limit: approximately 10 becquerel/liter).
 

2. Easy-to-understand publication of analysis results

 

The analysis results of tritium concentration in seawater in the sea area near the Fukushima Daiichi Nuclear Power Plant are available on the website of the Ministry of Economy, Trade and Industry (METI) in the form of a mark that shows the results at a glance.
