Fusion plants according to current projected designs would not, in fact, be appreciably safer. It is academic, because they would be 10s to 1000s of times as expensive as what they would be competing with, so will not be built. D-3He reactors might someday find uses in the outer solar system, or in military rapid-deployment corps, if they turn out possible. But availability of 3He will always be a problem. Probably it will be bred by using solar power to accelerate protons.
