Not exactly true. Nuclear can be built close to where the power is consumed. Wind power has to be built where geography co-operates. This means wind power, on average, requires significantly more transmission line capacity than nuclear.
Well it is pretty much true because it's not likely we would build a nuclear plant downtown in each community it is meant to serve. There will be central locations and the power will be streamed to the consumers. However we already have a pretty well established grid system so re-attaching the wires to a different type of plant wouldn't be all that big a deal. Of course growing population will require expansion.
