[Can’t stop leaking] 6.4 billion Bq leaked from the pump on transferring to the safer reservoir

About the major leakage of highly contaminated water, Tepco has officially admitted the reservoir No.1, 2 and 3 are leaking.

Tepco is transferring the highly contaminated water to other reservoirs to avoid further leakage but on 4/11/2013, they had the water leak from the joint of pump when they transfered water from No. 3 to No.6.

They reported this below. English version of the latest report is not published yet.

 

Though the water transfer from the underground reservoir No.3 to No.6 was started at 2:00 PM on April 11, the transfer pump was suspended at 2:03 PM on the same day as leakage from the connection part (flange) of the transfer pump outlet pipe was found.

The leakage has stopped after the transfer pump was suspended. The leaked water has been absorbed into the soil.

The leakage is currently being investigated in details.

 

According to Tepco, the volume of leaking water was 22L. The water contained 2.9×10^11 Bq/m3. In total, 6,380,000,000 Bq of β nuclide leaked.

It was absorbed by soil. Now Tepco is preparing to remove the soil.

[Ça n’arrête pas de fuir] 6,4 milliards de Bq ont fuit à partir de la pompe de transvasement vers un réservoir plus sûr

 

Sur la fuite majeure d’eaux extrêmement radioactives, Tepco a officiellement admit que les réservoir N°1, 2 et 3 fuient.
Tepco transvase les eux extrêmement radioactives dans d’autres réservoirs pour arrêter les fuites mais le 11 avril 2013 ils ont une fuite sur le joint de la pompe en transvasant l’eau du N°3 au N°6.
Ils le rapportent ainsi, la version anglaise de ce rapport n’est pas encore publiée :

Bien que le transvasement de l’eau du réservoir enfoui N°3 dans le N°6 ait commencé à 14:00 ce 11 avril, la pompe de transfert a été arrêtée à 14:03 le même jour parce qu’on a une fuite au raccordement entre la sortie  de la pompe de transfert et le tuyau (collerette).
La fuite a été arrêtée après l’arrêt de la pompe de transfert. L’eau ayant fuit a été absorbée par le sol.
La fuite est actuellement examinée en détail.

Selon Tepco, le volume qui a fuit est de 22 L. Cette eau contenait 290 000 000 000 Bq/m³. Au total, 6 380 000 000 Bq de β nucléides ont fuit.
Ils ont été absorbés par le sol. A présent Tepco organise le retrait de ce sol.
