Nope. JET achieved Q~0.7 in 1997[1],and that hasn't been beat since. In 1998, JT-60 would have gotten Q~1.2, had they put deuterium-tritium fuel [2] (but it wasn't built for that). You might be thinking of some news from NIF. In 2013, they sorta claimed to have reached ignition, but that was only by moving the goal-posts.[3] ITER is not by any means a test of an economical or scalable reactor -- it's still at the stage of a science experiment.
