well it surely has its advantages but it still requires a lot of (expensive) experiments to overcome technical problems, and we still lack technology to recycle waste from such reactors. the waste is about as dangerous as the one from uranium reactors.
i think it does have some future, though.
but nuclear power plants (of any kind) are too expensive to build (unless its build-n-dont-care style) and run. if you count big initial costs+fuel+waste handling+safety+political risk (you build powerplant, someone comes and says "close it" – see austria case), price/output ratio isnt as good as it seems to be.
in my opinion, various gas-powered combined cycles have brighter future (good effectivity, lower safety risks, doesnt pollute as much as uranium mines do). at least until we get something really supereffective and relatively safe.
