Con un servizio postato alle 21 di oggi ora locale (le 13 in Italia) la televisione giapponese NHK ricostruisce le fasi della battaglia per raffreddare la centrale di Fukushima e i suoi 4 reattori, nel N.4 ieri mattina si è infatti verificata una esplosione che ha più che probabilmente danneggiato il nucleo del reattore.
Efforts to cool Fukushima reactors continue
More problems hit the disaster-stricken Fukushima Number One power plant on Monday and Tuesday despite efforts to cool down the facility’s overheated reactors.
Shortly after 6 AM on Tuesday, an explosion was heard at the plant’s No. 2 reactor. The explosion is believed to have occurred near a facility known as a suppression pool, which adjusts the pressure of the reactor.
After the blast, pressure in the facility dropped rapidly. The Nuclear and Industrial Safety Agency suspects the facility was damaged and leaked radioactive materials.
The water level in the reactor had dropped, and fuel rods are believed to have been fully exposed for 6 and a half hours from Monday evening.
The Tokyo Electric Power Company is continuing to inject seawater into the reactor.
An explosion occurred at the plant’s No. 3 reactor on Monday, blasting off the ceiling and outer walls of the reactor building and injuring 11 workers and Self-Defense Force members. Five of the injured were found to be contaminated with trace amounts of radioactive materials.
The government and the company say the reactor’s nuclear containment vessel is still functioning, and that the pressure level in the reactor is stable. Work to inject seawater to cool down the reactor resumed early on Tuesday.
Around midnight on Tuesday morning, work resumed to inject water into the plant’s No. 1 reactor, where a hydrogen blast occurred on Sunday.
The work had been suspended early on Monday after a pump stopped working. The water level and pressure in the reactor are reportedly stable.
Shortly after 6 AM on Tuesday, an explosion was heard at the plant’s No. 4 reactor. Damage was later found around the ceiling of the reactor building.
At around 9:30 AM, a fire broke out around the 4th floor, but was later confirmed to have gone out.
