Japan's nuclear crisis is now on par with Chernobyl, according to Japanese authorities who are now calling the situation at the Fukushima Daiichi nuclear plant a "major accident."
They have now raised the situation from a category "5" level accident, comparable with Three Mile Island, to a level "7" - the same as Chernobyl.
Ali Velshi and Kiran Chetry spoke with Arnie Gundersen, a nuclear engineer and chief engineer with Fairewinds Associates, on American Morning and asked him what this means in terms of trying to control the plant.
