Report: Japan’s Fukushima reactor possibly melted twice, BNO News (Channel 6), August 8 2011:
According to a study, the crippled Fukushima Daiichi nuclear power plant might have suffered a second nuclear meltdown, Kyodo news agency reported Monday.
According to the study, which was conducted by nuclear safety expert Fumiya Tanabe, fuel inside one of the plant’s nuclear reactors might have breached the bottom of a pressure vessel after melting again.
The fuel is believed to have been kept cool at the bottom of the pressure vessel since a nuclear meltdown was confirmed, but the cooling method would need further review if most of the fuel at the No. 3 reactor has fallen into the containment vessel underneath the reactor, the study said. [...]
Study says nuclear fuel at Fukushima reactor possibly melted twice, Kyodo News, August 8, 2011:
Study by Fumiya Tanabe, expert in nuclear safety
- Melted fuel “was believed to have been kept cool at the bottom of the pressure vessel”.
- Melted fuel “has possibly breached the vessel after melting again at the bottom of the vessel”.
- “Most of the fuel at the No. 3 reactor may have fallen into the containment vessel underneath”.
