Yep .... plenty of issues with nuclear including environmental and political considerations (hence my wistful desire to see the fusion issue cracked) .... however if CO2 reduction is your Holy Grail then, whether wind power is offshore (yes please!) or onshore (no thanks!!), then we either need storage capable of running UK demand for days on end (currently sci-fi territory) or some CO2 free backup baseload generation....which leaves carbon capture or nuclear.
