Nuclear power stations will still be costing money to look after hundreds of years after they have stopped providing power and the cost of the electricity doesn't include the decommissioning cost. Uranium is also a finite resource. I would take wind/wave any day.
The problem with wind turbines is that they *can't* really be removed, unless you've got an economical way of disposing of a thousand-tonne concrete block. I suppose you could dump it in Cumbernauld, they wouldn't notice...
You've got reactor configurations such as fast breeder reactors that can burn spent uranium fuel and convert it to plutonium, which (once you have enough of it) you can modify your reactor to run on. In practical terms what you would do is actually have two reactors, one set up each way, and a stockpile of spare fuel. You could get a couple of hundred megawatts from a site the size of the existing Longannet power station.
Then of course you've got pebble bed reactors - they don't really require any special safety systems to prevent them running away, because the reaction slows as they heat up. The working fluid for the reactor is nitrogen, which doesn't really become radioactive with use (unlike water or sodium, used in existing plants). A Dutch company have demonstrated a prototype 8MW power plant that will eventually fit into an artic trailer...
