Fukushima : Tepco voudrait faire s'évaporer l'eau contaminée / Fukushima: Tepco would want to evaporate the contaminated water

L’eau contaminée venant de la centrale nucléaire de Fukushima pourrait être évaporée ou stockée sous terre au lieu d’être renvoyée dans l’océan comme c’est le cas jusqu’à maintenant.

Tepco (Tokyo Electric Power Co) qui est responsable du nettoyage du site, relâche le tritium contenu dans les eaux usées dans l’océan. Cependant, Tepco a essuyé plusieurs revers suite à des protestations de pêcheurs locaux, en lutte pour leur survie après l’accident de la centrale en 2011, après le tremblement de terre et le tsunami.

L’eau est utilisée pour refroidir les réacteurs afin de prévenir de nouveaux rejets radioactifs mais il n’existe aucune technologie pour retirer le tritium de cette eau.

Le responsable de la décontamination, Naohiro Masuda, a annoncé à Reuters qu’il ne savait pas quand la décision de laisser s’évaporer ou non ces eaux serait prise.

This comes as low-level radiation produced by the tsunami-stricken Fukushima nuclear power plant in Japan has been detected off the coast of Canada.

TEPCO is in a race against time to contain the wrecked nuclear facility. Management of the situation has likewise been marked by mishaps and scandalous revelations that have put a serious dent in the company’s reputation.

The plant’s operator announced a week ago its plans to disclose all data on radiation levels recorded at the site in response to mounting criticism over its lack of transparency.

In late February, TEPCO admitted to concealing a radioactive leak for 10 months, citing an ongoing investigation.

Earlier this year the company also admitted it won’t be able to process the radioactive water stored at Fukushima plant by March, as the operator had promised before. TEPCO’S president said the delay is due to technical problems.

Following the 1979 Three Mile Island nuclear disaster in the US, the cleanup crew used the evaporation method with success, but the amounts of water were much smaller.

Three of the Fukushima plant’s reactors suffered nuclear meltdown following an earthquake and tsunami on March 11, 2011 - becoming the world’s worst nuclear disaster since Chernobyl in 1986.

The water used to keep the reactors cool is tainted with radioactive material and has since been leaking and mixing with groundwater that is seeping through the facility.Lire la suite sur RT »
