A top official from the U.S. Nuclear Regulatory Commission said on Wednesday it was not clear that Japan's Fukushima No. 2 nuclear reactor has melted through the reactor pressure vessel.Now when you click on the link provided you will discover that the article has been taken down by Reuters. It was there before, we confirmed that. Now:
Earlier, Democratic lawmaker Edward Markey told a House of Representatives hearing on the nuclear disaster that the NRC had told him the core had melted through the vessel.
"That's not clear to us, nor is it clear to us that the reactor has penetrated the vessel," said Martin Virgilio, deputy executive director for reactor and preparedness programs at the NRC.

Further proof that Reuters did write something about it. Google must be slipping leaving that remnant there.
