The massive infrastructure required, design, maintenance, security, contaminated parts, etc., requires massive amounts of money and energy to keep going. Even for the "fast breeder" reactors, there are significant technological challenges that have yet to be totally overcome. In some locations, it works ok due to several factors, but it's far from some windfall that solves everything. It's more energy efficient to use gas-turbines in cities. Even if you are powering an electrical car, it's more efficient to use the gas-turbine to make electricity and send it to the grid. They passed the 50% efficiency barrier years ago and are around 65% total efficiency, which is pretty amazing. If you need more power, installing another gas-turbine unit is relatively quick and easy. It's fossil fuel, but a far better way to use it, not to mention other options of renewable sources. If you really do the research on nuclear you'll see it's not practical in many/most places, it ends up sucking way too much energy and resources.
