Potrebbe essersi parzialmente sciolta la barriera protettiva di ghiaccio intorno alla centrale di Fukushima, scenario del gravissimo incidente nucleare del 2011.
È quanto riferisce oggi, venerdì, l'emittente giapponese NHK. La società TEPCO, che gestisce l'area dell'impianto oggi dismesso, prevede ora di puntellare questa parete sotterranea già a inizio dicembre e starebbe valutando ulteriori contromisure.
La barriera, che ha uno spessore di 7 metri ed è alimentata da tubi di refrigerazione, ha la finalità di isolare la centrale, impedendo in tal modo il riversamento di acque contaminate dalla radioattività nelle falde acquifere.
