New attempts to fill the reactor at Fukushima Dai-ichi reactor No. 2 with seawater has failed, exposing the fuel rods to air for a second time at 11:20 p.m., a Tokyo Electric Company Co. (TEPCO) official said at a news conference moments ago.

Officials described the reading of the water level as “downscale,” which indicates the lowest possible level of water within the reactor. When reporters pressed the officials if this could cause a meltdown, they gave a vague answer and hinted that it could.

The officials confirmed when the rods were first exposed earlier in the evening it was for about two hours.

Fukushima Dai-ichi Reactor #2 Core Exposed! Water Now filling Chamber

TOKYO (majirox news) – Nippon Television reported that efforts to cool down Reactor #2′s core had failed, and as of 7:54PM nuclear core was no longer underwater within the reactor’s chamber. According to government spokesman Yukio Edano,  the reactor’s staff believes that the core was almost completely exposed. This created the strong possibility of an imminent meltdown. However, as of 8:07 PM, seawater was being pumped into the chamber after the pump’s initial failure.

Workers at the plant were implementing their plan to cool the reactor by pumping seawater into the vessel, but the staff was unaware that there was a problem with the pumps,  and contrary to their expectations the temperature continued to rise. The remainder of the water in the chamber evaporated, exposing the core to air.

The pumps were repaired and now the chamber is filling with seawater.

More details to follow.
