No it is not. If you calculate in the future money tax payers have to pay to keep the nuclear waste safe (for thousands of years) or the cost of a larger incident like Chernobyl or Fukushima which also has to be paid by the tax payers then the 'cheap nuklear power' is not so cheap as it looks like...
The disasters like Chernobyl and Fukushima are symptoms of a greater issue: construction and maintenance of an extremely volatile and sensitive process reliant upon the integrity of infrastructure and quality of manpower.
Nuclear requires a stable society and economy flush with resources and education and little to no risk of political stability.
Those places are welcome to invest heavily into nuclear while CO2 concentrations build up as emmissions continue unabated.
