Nuclear physicist Dr Walt Patterson tells the BBC it sounds
like there is a "serious problem" at the Fukushima-Daiichi
plant. "It's the sort of thing that nuclear engineers have
nightmares about," he says. "If it is not resolved in the
next few hours it will get serious. If the core is uncovered,
then those rods at the top may get hot enough to melt themselves."
