PITTSBURGH- A debate over whether turbulence would cause heat to leak from a prototype fusion reactor--the projected $10 billion International Thermonuclear Experimental Reactor (ITER)--received fresh fuel at a tense session of last week's meeting here of the American Physical Society's division of plasma physics. A new set of calculations suggests that fusion reactors like ITER would leak heat more slowly than predicted by the model that set off the debate last year. But nobody is ready to say that the results put ITER in the clear, as researchers have been unable to pinpoint why the predictions differ under some conditions.
