Nuclear power is not very dangerous until an accident occurs. It is not like a coal plant where 30 years of cleanup means all traces of damage are corrected.
If we just built reactors deep underground, disasters such as Fukushima would be a non-issue. Plug the hole and move on. Unfortunately we have so many reactors on fault lines, bodies of water just waiting to be flooded, attacked, or otherwise damaged they can essentially become a dirty bomb with all of the on-site waste located there.
We are not doing the right thing by building these plants so close to water supplies and at sea level or near oceans and fault lines. Build them deep underground. When fuel is expended, bury the fuel, then the reactor later on. Problem solved.
“Problem solved.”
The KEY point being:
The problems are solvable.
There is no need to abandon nuclear power.
