Why nuclear energy is not relevant in our days?

Uranium itself needs to be enriched, this happens at special plants.And only after that, uranium can be added to the fuel cycle of energy release. The USA has the most extensive experience in nuclear energy, they have 99 nuclear power plants in which 804 billion kWh per year is allocated. If we calculate in general, in 2016, the world's nuclear power plants produced 2477 billion kWh of energy in total.
