An explosion at a Japanese nuclear plant triggered fears of a meltdown Saturday after a massive earthquake and tsunami left more than 1,000 dead and at least 10,000 unaccounted for.
Ron Chesser, director of the Center for Environmental Radiation Studies at Texas Tech University, said it was critical to cool the reactor core to avoid a meltdown that would result in “a large release of radiation”.
“Reactors are not like your car that you can turn off and walk away. They’re going to continue generating a great amount of heat until the core is disassembled,” he told the US-based ScienceDaily website.
