Fuel is hardly the only advantage, the major issue with fission is the enormous costs of trying to avoid problems or cleanup after them. Thus 24/7 security, redundancy on top of redundancy, walls thick enough to stop aircraft etc. Fission is still by far the most expensive power source even with massive subsides and is only even close to economically viable as base load power backed up with peaking power plants.
In theory much of that is excessive but there is a long history of very expensive mistakes with massive cleanup efforts. The US talks about three mile island as the largest nuclear accident ignoring the Stationary Low-Power Reactor Number One that killed 3 people. All that complexity and expense comes from trying to avoid real mistakes that actually happened.
