[Is it already discharged ?] Tritium and Sr-90 density in sea water doubled in the latest data

According to Tepco, tritium and Sr-90 density in sea water picked up last December. The sampling location is about 30m point in north of reactor5 and 6 discharge channel.

Officially they haven’t discharged the retained contaminated water to the sea.

Tepco releases the report about tritium and Sr-90 density irregularly, and they don’t release the graph of historical readings.

The graph below is made by Fukushima Diary based on Tepco’s reports.

It shows the tritium and Sr-90 readings increased to be as double as the highest readings before.

Additionally, the sampling date was 12/10/2012. There is no explanation about why they took 3 months to release the data.

[Déversement déjà commencé ?] La concentration du tritium et du Sr-90 dans l’eau de mer a doublé dans les derniers relevés

 

Selon Tepco, la concentration du tritium et du Sr-90 de l’eau de mer augmente rapidement depuis décembre dernier. Le point d’échantillonnage et à environ 30 m au nord du canal déversoir des réacteurs  5 et 6.
Officiellement, ils n’ont pas déversé d’eau contaminée dans la mer.
Tepco publie irrégulièrement un rapport sur les concentrations en tritium et Sr-90 et ils ne publient pas le graphique des mesures au cours du temps.
Le graphique ci-dessous est fait par le Fukushima Diary sur la base des rapports de Tepco.
Il montre que le tritium le Sr-90 ont doublé les plus hauts records précédents .
De plus, la date d’échantillonnage était au 10 décembre 2012. Il n’y a aucune explication au fait qu’il leur a fallu 3 mois pour publier ces données.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
