Are there any fusion reactors in the process of use or being built to work with the possiblity of helium 3 for fuel?

Since the fusion cross section for He 3 is smaller than for deuterium and tritum, it is not where people start. The next step would likely be deuterium, deuterium, avoiding the extra neutron. You might check with Princeton Plasma Physics Lab to see status of this. But the probable answer is "not yet".
