Tepco’s camera caught possible living creature inside Reactor 3 vessel of 1 Sv/h

Following up this article.. [Video] Tepco investigated the inside Reactor 3 vessel / 1 Sv/h, “sediment” accumulated [URL]


In the follow-up investigation, Tepco’s camera caught possible aquatic living creature in retained coolant water of Reactor 3. This video was recorded and released on 10/22/2015 by Tepco.

This is the inside of PCV 3 (Primary Containment Vessel of Reactor 3). In their previous investigation, 1 Sv/h was detected above the water surface. Yellow-ish sediment was observed accumulating in the water as well.

The possible living creature is recorded from approx. 0:19 of the video. It looks like aquatic microbe, which is independently swimming unlike other substances.

The attached GIF was edited by Fukushima Diary. It contains the zoomed (200% and 300%) parts to capture the creature more closely.

Durant l’exploration la caméra de Tepco a sans doute enregistré un être aquatique vivant dans le liquide de refroidissement du réacteur 3.

Cette vidéo a été enregistrée et publiée le 22 octobre 2015 par Tepco. C’est l’intérieur de la PCV3 (Primary Containment Vessel of Reactor 3 = Enceinte de confinement primaire du réacteur 3).

Ils avaient relevé 1 Sv/h au dessus de la surface lors de leur précédente exploration. On observait également des sédiments jaunâtres s’accumulant dans le liquide.

La créature vivante apparaît dans la vidéo à à peu près 0:19. On dirait un microorganisme aquatique nageant librement, contrairement aux autres substances. Les GIF joints sont de Fukushima Diary. Ce sont des extraits zoomés (200% et 300%) de la vidéo cherchant à montrer la créature de plus près.



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.
