20 L of oil leaked from Concrete Pumping Vehicle in Fukushima nuclear plant

According to Tepco, a sub-contract worker found 20 L of oil leaking from the pumping vehicle in Fukushima nuclear plant.

They reported as below,

At around 2:00 PM on May 28, while conducting a monthly inspection of a concrete pumping vehicle at the parking outside of the main gate, a cooperative company worker found oil leakage from a hydraulic pressure hose connected to a hydraulic pressure indicator for oil used for operation when checking the behavior of such devices as a safety device against overturning.

Operation of the concrete pumping vehicle was immediately stopped. Then, a pail can was brought to accommodate leaked oil, oil leaked on the vehicle and the ground was wiped out, and the hydraulic hose from which oil leaked was separated. Consequently, the leakage was confirmed to have been stopped.

Approx. 18 liters of oil was accommodated by the pail can, and approx. 2 liters of oil leaked onto the ground. The total amount of leaked oil is therefore approx. 20 liters.


On 5/20/2013, Fukushima Diary reported Tepco had a crane leak 20L of oil beside reactor3 SFP. They had sub-contract worker wipe it off manually by rag after all. (cf, Tepco had subcontract workers manually wipe out the leaking oil by rag beside reactor3 [URL])

Dans la centrale nucléaire de Fukushima, 20 L d’huile ont fuit d’un camion à béton


Selon Tepco, un ouvrier sous-traitant a découvert 20 L d’huile ayant fuit d’un camion à béton dans la centrale nucléaire de Fukushima.

Ils le rapportent ainsi :

Le 28 mai vers 14:00, tout en effectuant une inspection mensuelle sur un camion à béton dans le parking à l’extérieur de l’entrée principale, un travailleur d’une société coopérative a découvert une fuite d’huile sur un tuyau de pression hydraulique relié à un manomètre de pression d’huile utilisé pour contrôler le comportement de ce genre d’appareils en sécurité contre le renversement.

L’opération sur le véhicule de pompage de béton a immédiatement été arrêté. Ensuite un seau a été apporté pour limiter la fuite d’huile, l’huile ayant fuit sur le véhicule et au sol a été nettoyée et le tuyau à l’origine de la fuite a été isolé. En conséquence, l’arrêt de la fuite a été confirmé.

Approx. 18 litres d’huile ont été récupérés dans le seau et approx. 2 litres d’huile ont fuit au sol. La quantité totale de la fuite d’huile est donc d’environ 20 litres.

Le 20 mai 2013, le Fukushima Diary publiait que Tepco avait eu une fuite de 20L d’huile d’une grue à côté de la SFP du réacteur 3. Ils avaient fait nettoyer manuellement par des ouvriers sous-traitants avec des chiffons au final. (cf. Tepco envoie les sous-traitants nettoyer la fuite d’huile à la main avec des chiffons, à côté du réacteur 3)

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.
