in the past OIL was abundant, so there was no need of nuclear power plants considering its risks. But times have changed. OIL has reached a phenomenon called as PEAK OIL where production will start decreasing shortly. Considering PEAK OIL Phenomenon and considering climate change where most of the CO2 is released due to burning of OIL and Coal, nuclear energy is a viable alternative in the short-term or the medium-term, before we really switch to renewable sources of energy even more fully. All sources of energy have drawbacks even renewable sources but you should consider the context and the position the country is in.
