Japan nuclear plant confirms meltdown of two more reactors  

Posted by Big Gav in , , ,

The Guardian reports that Tepco has admitted that reactors 2 and 3 at Fukushima also suffered meltdowns - Japan nuclear plant confirms meltdown of two more reactors. I can just hear the zealots at BNC squawking about how this isn't a big deal and how the nuclear renaissance is still just around the corner...

The operator of the Fukushima Daiichi nuclear power plant said fuel rods in two more reactors were likely to have suffered a meltdown soon after they were crippled by the 11 March earthquake and tsunami in north-east Japan.

Confirmation by Tokyo Electric Power (Tepco) that fuel in the cores of reactors 2 and 3 had melted came days after new data confirmed a similar meltdown in reactor 1 about 16 hours after the disaster.

The utility, which last week suffered the biggest annual loss by any Japanese firm outside the financial sector, said most of the melted fuel in all three reactors was covered in water and did not threaten to compound the world's worst nuclear accident since Chernobyl. ...

It said the fuel rods in the reactors 2 and 3 had started melting two to three days after the earthquake and tsunami, which knocked out vital cooling systems.

Tepco officials repeated their insistence that the reactors had been crippled by the waves, but speculation has mounted in recent days that the quake itself had been responsible, casting doubt on Tepco's claims that the plant was able to withstand even the most violent seismic shifts.

Most of the fuel damage that occurred in reactor 2 is believed to have taken place within 100 hours of the earthquake. TEPCO believes fuel was damaged in reactor 3 within 60 hours. The company previously confirmed that fuel was damaged in reactor 1. TEPCO plans to install two heat exchangers today to lower the temperature of the used reactor fuel at reactor 2.
