[Oil leakage again] Lubricating oil leaked from desalination system / 1.5m x 1m x 1mm

Oil leakage accident has been happening in Fukushima nuclear plant frequently.

Tepco announced contaminated water desalination system had the oil leakage as well. It was lubricating oil.

According to Tepco, it was 1.5m x 1m x 1mm area. The press release is below,

At around 5:00 AM today (July 22), an associated company worker found oil leaking near a high-pressure pump of the desalination system 3 (RO-3-1) in Fukushima Daiichi NPS.

The high-pressure pump was suspended, and the oil leakage was confirmed to be stopped as a result of a visual inspection at the site around 6:00 AM.

The leaked oil was lubricating oil accumulated on a weir of concrete floor, and leaked range is estimated to be approx. 1.5 liters (approx.1.5m x approx. 1m x approx. 1mm).

The incident was reported to Tomioka fire department at 5:45 AM today (July 22).

We will continue to inspect the condition and the cause of the leakage.

[fuite d’huile, encore] De l’huile fuit du système de désalinisation / 1,50 x 1 m x 1 mm

 

Il y a souvent des fuites d’huile accidentelles à la centrale nucléaire de Fukushima.

Tepco déclare que le système de désalinisation des eaux contaminées a aussi une fuite d’huile. C’est de l’huile de lubrification.
Selon Tepco, ça couvrait 1,50 m x 1 m x 1 mm. Le communiqué de presse :

Aujourd’hui (22 juillet) vers 05:00, un travailleur sous-traitant a découvert une fuite d’huile près d’une pompe à haute pression du système de désalinisation 3 (RO-3-1) dans la NPS de Fukushima Daiichi.
La pompe à haute pression a été suspendue et la fuite en a été confirmée stoppée sur inspection visuelle du site vers 06:00.
L’huile de la fuite était de l’huile de lubrification accumulée le long d’un barrage de béton au sol et l’étendue de la fuite est estimée à approx. 1,5 litres (approx.1,5 m x approx. 1 m x approx. 1 mm).
L’incident a été signalé aux pompiers de Tomioka aujourd’hui (22 juillet) à 05:45.
Nous allons continuer d’inspecter les conditions et la cause de la fuite.

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.
