Insults do not help your arguments.
If you don't use nuclear power (once the power station is built) you lose it. Exactly the same as solar and wind. You can turn solar and wind off if you want, exactly the same as nuclear power, but economic reasons make it infeasible to do so very often, again exactly the same as nuclear power.
Nuclear power is notoriously difficult to integrate into the grid; you need a lot of fossil fuel or hydro plants to handle the peak load that nuclear cannot handle economically.
