Plutonium-239/240 detected from 2 discharge channels and 3km offshore of Fukushima nuclear plant

According to Tepco, Plutonium-239/240 were detected at 3 locations around Fukushima nuclear plant. The sampling dates are early April of 2013.

0.013 Bq/m3 from North of reactor5&6 discharge channel.

0.0014 Bq/m3 from around south discharge channel.

0.0057 Bq/m3 from 3km offshore of Fukushima nuclear plant.

As to the detection of Plutonium-239/240 in 3km offshore of Fukushima nuclear plant, Tepco denied the connection with Fukushima nuclear accident as below,

Given that the density level of Pu-239+Pu-240 detected at 3km Offshore of Fukushima Daiichi NPS,
Upper Layer on April 2, 2013 is within the range of the past density measurements conducted along
the seacoasts of 1F and 2F, it cannot be stated with absolute certainty that the presence of these
particles is due to the accident.

However they admitted the connection with Fukushima nuclear accident about the Plutonium-239/240 detection from around south discharge channel.

Given that the density level of Pu-239+Pu-240 detected at 1F, Around South Discharge Channel on
April 9, 2013 is higher than the past density measurements conducted along the seacoasts of 1F
and 2F, it can be stated that the presence of these particles is due to the accident.

Du plutonium 239/240 détecté dans 2 déversoirs et à 3 km au large de la centrale nucléaire de Fukushima

 

Selon Tepco, du plutonium 239/240 a été relevé en 3 points autour de la centrale nucléaire de Fukushima. Les échantillons datent de début avril 2013.

0,013 Bq/m³ au nord du déversoir des réacteurs 5 & 6.
0,0014 Bq/m³ à proximité du déversoir sud.
0,0057 Bq/m³ à 3 km au large de la centrale nucléaire de Fukushima.

Concernant la détection de plutonium 239/240 à 3 km au large de la centrale nucléaire de Fukushima, Tepco nie ainsi le lien avec l’accident nucléaire de Fukushima :

Compte tenu que le niveau de densité des Pu-239+Pu-240 relevés à 3 km au large de Fukushima Daiichi NPS,
Au 2 avril 2013, la couche supérieure est dans la fourchette des mesures passées et menées le long des rivages de F1 et F2, on ne peut affirmer avec absolue certitude que la présence de ces particules soit due à l’accident.

Cependant, ils admettent le lien entre l’accident nucléaire de Fukushima et la détection de plutonium 239/240 autour du déversoir sud :

Compte tenu que le niveau de densité des  Pu-239+Pu-240 détecté le 9 avril 2013 à F1 autour du déversoir sud est supérieur aux mesures passées effectuées le long des rivages de F1 et F2, on peut affirmer que la présence de ces particules est due à l’accident.

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.
