mdsolar writes "At a second meeting Thursday related to the Fukushima Daiichi crisis, a U.S. Energy Department official warned that the nuclear facility still faces grave danger.
John E. Kelly, deputy assistant secretary for nuclear reactor technologies, said that protective components at the facility could crack because of high salt levels. There “is still a concern about more massive failure” of steel in the “lower head,” an important part of the containment system, Kelly told an NRC advisory committee. About 100 to 200 tons of salt left by the emergency pumping of salt water to cool the reactors are probably corroding the containment components."
