About This Video

Arnie Gundersen, Chief Engineer of Fairewinds Associates, praises the Japanese for scrapping a plan to drop water on to the overheating fuel pools from helicopters. Gundersen explains that it's a risky move. If the the falling water causes the spacing of the gaps between spent fuel rods to shrink, Gundersen says, a new reaction (or criticality) might develop.
